Individual Rulings (L-R)

These rulings have been lifted from the 2005-era upperdeck web archive and therefore reflect the rulings from the Goat Format time period. They are listed in alphabetical order, but you can use use ctrl+f to quickly find the card that you want.

Note: Some of the rulings refer to cards as having a "multi-trigger effect." This was the old term for what is now known as a "quick effect", ie a monster effect that is spell speed 2 and can be used on the opponent's turn.

LABYRINTH OF NIGHTMARE


This will activate the effect of "Dream Clown".



LADY ASSAILANT OF FLAMES


If you have fewer than 3 cards in your Deck when this card is flipped face-up its Flip Effect does not activate.

Removing 3 cards from the top of your Deck is part of the resolution of this card’s Flip Effect, not part of the cost. So if its Flip Summon is negated by "Solemn Judgment" you do not remove any cards from the top of your Deck.



LADY NINJA YAE


Discarding 1 WIND monster is a cost.



LAST TURN


“Last Turn” is a very special Trap Card with very special and unusual rules. The most important thing to understand about “Last Turn” is that not all of its effects are applied when the Trap Card resolves. When “Last Turn” (the Trap Card itself) resolves, the activating player selects 1 monster on their side of the field, and all other cards on the field and in both players’ hands are sent to the Graveyard. That is all that happens when “Last Turn” resolves. After that, the turn player Special Summons 1 monster from their Deck. After that, a special Battle Phase occurs. Then, during the End Phase, the victory check of “Last Turn” is applied. “Last Turn” sets up several effects that resolve later in the turn long after the Trap Card itself has resolved. Several other cards do this too, like “Last Will” and “Change of Heart”.

Suppose that “Ceasefire” is activated (Chain Link 1), and “Last Turn” is chained to it (Chain Link 2). In this case, “Last Turn” resolves first, the activating player selects 1 monster on their side of the field, and all other cards are sent to the Graveyard. Then resolve the effect of “Ceasefire” (Chain Link 1). After “Ceasefire” resolves, the turn player Special Summons a monster for “Last Turn”, then the special Battle Phase occurs, then in the End Phase the victory check is applied. This is an example of how the special nature of “Last Turn” works: the only thing that happens when “Last Turn” resolves is to select 1 monster and send all other cards to the Graveyard.

“Last Turn” is not a card that Special Summons a monster when it resolves. Therefore you can activate “Last Turn” even while “Jowgen the Spiritualist” is face-up on the field. If the player activating “Last Turn” controls “Jowgen the Spiritualist” and selects it as the monster to keep, the opponent cannot Special Summon for “Last Turn”, and there will be no special Battle Phase. However the victory check is still applied in the End Phase.

The special Battle Phase for “Last Turn” happens right after the monster is Special Summoned. It is in addition to the normal Battle Phase and does not disrupt the normal order of the turn. For example, if “Last Turn” is activated during the Draw Phase, resolves the effect, Special Summon, initiate the special Battle Phase, then continue with the Draw Phase. The turn player can have a normal Battle Phase later in the turn.

The special Battle Phase is treated like a standard Battle Phase in every other way, with a Start Step, Battle Step, Damage Step, and End Step. Only the selected monster and the Special Summoned monster can battle.

If you activate “Last Turn” and select your “The Rock Spirit” or “Soul of Purity and Light” their effects will be applied during your opponent’s special Battle Phase. Also any Flip Effects are resolved as normal, etc. You can use the effect of “Injection Fairy Lily” and other monster effects during the special Battle Phase.

The effect that reduces Battle Damage to zero applies only for the special Battle Phase, not for the normal Battle Phase. Example: A player activates “Last Turn” and selects their Defense Position “Spirit Reaper”. The turn player Special Summons “Enraged Battle Ox” and attacks in the special Battle Phase, but no damage occurs. However, during the turn player’s normal Battle Phase they can attack again, and will inflict 1500 points of damage due to the effect of “Enraged Battle Ox”, so the opponent’s Life Points will be zero and the turn player will win.

If the Battle Phase is skipped because of “Thunder of Ruler” or “Soul Exchange”, resolve the effects of “Last Turn” as much as possible (including victory check, quite possibly resulting in a DRAW).

You can chain to the activation of “Last Turn” with cards like “Ring of Destruction”, “Offerings to the Doomed”, or “Compulsory Evacuation Device” to eliminate the opponent’s monsters. If the player who activated “Last Turn” has no monsters on the field when it resolves, the effects of “Last Turn” are not negated. So the turn player still Special Summons a monster, although the special Battle Phase is not conducted, but the victory check in the End Phase is still performed.

The victory check for “Last Turn” is an effect that must be resolved by the player who activated it. The turn player still has priority to activate and resolve any other effects first. You cannot chain to the victory check of “Last Turn”.

If your opponent activates “Last Turn” and you Special Summon “Dark Magician of Chaos” from your Deck, you can activate his effect to add a Spell Card from your Graveyard to your hand.

After “Last Turn” sends all cards to the Graveyard, before the Special Summon for “Last Turn” is performed, monster effects like “Despair from the Dark”, “Elephant Statue of Disaster”, and “Regenerating Mummy” will activate.

If “Night Assailant” is sent from the hand to the Graveyard by the effect of “Last Turn”, resolve the effect of “Night Assailant” before Special Summoning for “Last Turn”.

If your opponent activates “Last Turn” and you Special Summon a monster that can attack twice, it can attack twice during the special Battle Phase (important if the opponent had a monster like “Big Core”).

“Last Turn” as a chain to “Change of Heart”: Suppose the turn player activates “Change of Heart” and the opponent chains “Last Turn”, then the opponent selects the monster targeted by “Change of Heart” for “Last Turn” (since it’s still on his side of the field, as “Change of Heart” hasn’t resolved yet). Then “Change of Heart” resolves and the turn player gains control of the monster, then Special Summons for “Last Turn”. There is no special Battle Phase. Assuming that the opponent somehow survives the standard Battle Phase, during the End Phase, the turn player has priority to activate and resolve an effect. If the turn player activates and resolves “Change of Heart”, then the monster goes back to the opponent and (assuming nothing else has happened), both players each have 1 monster and the result is a DRAW. If the turn player passes priority to the opponent, the opponent can activate and resolve the effect of “Last Turn” before “Change of Heart”, and in this case the turn player still has 2 monsters and the opponent has zero, so the turn player would win. If the turn player passed priority to the opponent and the opponent passes it back, the turn player MUST activate and resolve an effect, so the effect of “Change of Heart” would expire and both players would have 1 monster each, resulting in a DRAW.

You cannot Special Summon a monster for “Last Turn” that is a “Special Summon-only” monster like “Chaos Emperor Dragon – Envoy of the End”, “Dark Necrofear”, or “Ocean Dragon Lord – Neo-Daedalus”. Nor can you select a Spirit Monster because they cannot be Special Summoned.

You CAN Special Summon a high-level monster that has no Special Summoning restrictions for “Last Turn”, such as “Blue-Eyes White Dragon” or “Dark Magician of Chaos”.

If you activate “Last Turn” and select your face-up “Thousand-Eyes Restrict”, the turn player cannot attack so unless they can destroy your “Thousand-Eyes Restrict” with a card effect, each of you will have a monster during the End Phase and the Duel will end in a DRAW.

While your Life Points are 1000 or less, you can activate “Last Turn” in any part of your opponent’s turn, except the Damage Step. You can even activate it during the End Phase.

If “Last Turn” is activated and the turn player has no monsters to Summon, there is no battle however the victory check is still applied.

If you activate “Last Turn” during the Draw Phase or Standby Phase, and select your face-up “Jowgen the Spiritualist”, your opponent can still retrieve their “Sinister Serpent”, Summon it normally in Main Phase 1, and attack and destroy “Jowgen the Spiritualist” in the normal Battle Phase, then win the Duel in the End Phase because of the victory check of “Last Turn”.

If “Jinzo” is Special Summoned by the effect of “Last Turn”, “Jinzo” does not negate the special Battle Phase or victory check because “Last Turn” has already resolved and been sent to the Graveyard, so it is no longer on the field for “Jinzo” to negate.

If a player’s Life Points are reduced to zero during the special Battle Phase of “Last Turn”, or afterwards during the normal course of the turn, then that player loses. Example: “Giant Germ” is Special Summoned by the turn player and is destroyed as a result of battle, and the opponent had 500 or fewer Life Points when activating “Last Turn”.

If you activate “Last Turn” and then your Life Points increase above 1000 later, the effects of “Last Turn” are still applied.

If the turn player Special Summons “Mystic Tomato” for “Last Turn”, and attacks, and “Mystic Tomato” is destroyed, its effect activates and a monster is Special Summoned, but that new monster cannot attack during the special Battle Phase. (But it can attack during the standard Battle Phase.)

If the turn player Special Summons “Sangan” for “Last Turn”, and “Sangan” is destroyed during the special Battle Phase, then its effect is resolved. If the turn player hasn’t Normal Summoned a monster that turn, they can Summon the monster retrieved with “Sangan” during their Main Phase (and attack during their standard Battle Phase). This can result in a DRAW.

If you activate “Last Turn” and select your “Dark Necrofear”, and it’s destroyed during the special Battle Phase, you can select which effect resolves first during the End Phase: “Dark Necrofear” or “Last Turn”. So you can choose to resolve “Dark Necrofear” first, equip it to your opponent’s monster and take control of it, then resolve “Last Turn” and win because only you control a monster.

Vs. “Sanga of the Thunder”, “Kazejin”, “Suijin”: If the turn player Special Summons any of these monsters for “Last Turn”, he cannot activate the effect. However, if the player who activates “Last Turn” selects one of these monsters, he can activate the effect during the special Battle Phase.

The monster selected by the player activating “Last Turn” can be face-up or face-down, in Attack or Defense Position.

If the turn player Special Summons “Twin-Headed Behemoth” and it is destroyed during the special Battle Phase, during the End Phase the turn player has priority to activate and resolve an effect first, so he can choose the effect of “Twin-Headed Behemoth” and Special Summon it to the field before the victory check of “Last Turn”.

If the effect of “Non Aggression Area” is being applied and you activate “Last Turn”, your opponent does not Special Summon from the Deck for “Last Turn”.

“Last Turn” does not target so you can select monsters like “Tyrant Dragon” and “Fiend Skull Dragon” for its effect, or a Dragon-Type monster while “King Dragun” or “Lord of D.” is on the field. You can select “Spirit Reaper” and it will not be destroyed by its effect.

You can activate “Last Turn” and select your opponent’s monster that you control with “Snatch Steal”. However, after selecting it, “Snatch Steal” is sent to the Graveyard so control of the monster returns to the turn player. The turn player then Special Summons for “Last Turn” but no special Battle Phase is conducted. The victory check is still conducted in the End Phase.

If you activate “Last Turn” and select a monster that was Special Summoned by “Call of the Haunted”, when “Call of the Haunted” is sent to the Graveyard by “Last Turn”, your selected monster is destroyed. But if you selected a monster Special Summoned by “Premature Burial”, the selected monster is not destroyed when “Premature Burial” is sent to the Graveyard by “Last Turn”.

If both monsters that battle for “Last Turn” are removed from play (such as with “D.D. Warrior Lady”) then the result is a DRAW.

If “Obnoxious Celtic Guard” battles a monster for “Last Turn”, its effect is applied and it is not destroyed if it battles a monster with 1900 or higher ATK.

“Waboku” can be activated before “Last Turn”, or be chained to the activation of “Last Turn”, and in either case the effect of “Waboku” will prevent the activator’s monster from being destroyed. This can lead to a DRAW.

If the turn player activated “Last Will” before “Last Turn” was activated, a monster can be Special Summoned by the effect of “Last Will” during the special Battle Phase (but it cannot attack during the special Battle Phase).

You can activate “Wall of Revealing Light” (paying its cost) and chain “Last Turn”.

If “Pyramid of Light”, “Andro Sphinx”, and “Sphinx Teleia” are all sent to the Graveyard by “Last Turn”, “Theinen the Great Sphinx” is not Special Summoned because the effect of “Pyramid of Light” activates its effect, but then looks for “Andro Sphinx” and “Sphinx Teleia” and does not find them on the field, so it cannot destroy them with its effect.

If the battle for “Last Turn” is conducted and the defending monster was “Wall of Illusion”, but it is destroyed, the attacking monster is returned to the turn player’s hand. The turn player can then Normal Summon the monster in the Main Phase (unless it has passed).




LAST WILL


You don’t select a monster as a target when you activate or resolve "Last Will". "Last Will" creates a state whereby, the next time during that turn when your monster is sent from your side of the field to your Graveyard, you may Special Summon 1 monster from your Deck using "Last Will’s" state. "Last Will’s" state then ends.

These states accumulate, so if you activate 2 "Last Wills", then the next time during that turn when your monster is sent from your side of the field to your Graveyard, you may Special Summon 2 monsters from your Deck, and the "Last Wills’" states then end.

You only Special Summon 1 monster for each 1 "Last Will".

The state will expire at the end of the turn, or when it is used, whichever comes first. So if you Special Summon using "Last Will’s" state, then the state is gone, and if the end of the turn arrives without using "Last Will’s" state, then the state is gone.

Last Will’s state will trigger by Tributing for a Tribute Summon, or for "Cannon Soldier’s" effect, etc.

You can use "Last Will’s" state to Special Summon a Level 5 or higher monster like "Labyrinth Wall".

You cannot Special Summon a "Special Summon-only" monster. You CAN Special Summon "Toon Mermaid" with "Last Will's" effect, as long as you have "Toon World" on your side of the field.

"Last Will’s" state is only triggered when your OWN monster is sent from YOUR side of the field to YOUR Graveyard.

If "Last Will’s" state is triggered during the Battle Phase by your monster being sent to your Graveyard, you resolve "Last Will’s" effect at that time (just like "Giant Rat") and the newly Summoned monster can attack before Main Phase 2.

If "Imperial Order" is activated after "Last Will" has resolved, it will not negate "Last Will's" state.

You can Special Summon a 1500 ATK monster that will have higher than 1500 ATK after being Summoned, such as a Fiend with 1500 original ATK while "Yami" is on the field and its ATK once Summoned will be 1700.

You can Special Summon "Muka Muka" even if you have 6 cards in your hand and "Muka Muka's" ATK, once Summoned, will be higher than 1500.



LAVA GOLEM


"Lava Golem" must be Special Summoned to your opponent’s side of the field using its effect text; you cannot Special Summon it or Tribute Summon it to your side of the field.

However, if Special Summoned correctly and then sent to the Graveyard, you can use "Monster Reborn" to Special Summon "Lava Golem" to your side of the field, but you (as the controller) will then take the 1000 damage during your Standby Phases.

You cannot Summon or Set and then Special Summon Lava Golem.

If you Special Summon "Lava Golem" onto your opponent’s side of the field they can activate "Bottomless Trap Hole" since you performed the Summon. You could not activate "Bottomless Trap Hole" even though the "Lava Golem" will be on their side of the field.

You can Tribute "Sheep Tokens" to Special Summon "Lava Golem" because it is not a Tribute Summon.

Since Tributed monsters are not considered to be targeted, you can use "Lava Golem" and Tribute your opponent's Dragons even if he has "Lord of D." on the field.

You cannot Special Summon "Lava Golem" if the opponent has "Jowgen the Spiritualist" face-up on the field, nor can you Tribute their "Jowgen the Spiritualist" to Special Summon "Lava Golem".



LEGACY HUNTER


If your "Legacy Hunter" attacks your monster (controlled by your opponent) on your opponent's side of the field, "Legacy Hunter'"s effect still activates and your opponent returns a card to the Deck.

If "Legacy Hunter" attacks a face-down "Man-Eater Bug" or "Cyber Jar", "Legacy Hunter"'s effect is not applied because "Legacy Hunter"'s effect activates when the monster he destroyed is sent to the Graveyard, and "Legacy Hunter" will no longer be on the field in these instances.

The monster that "Legacy Hunter" attacks must be face-down at the start of the Damage Step for "Legacy Hunter's" effect to activate. So if "Legacy Hunter" attacks a face-down Defense Position monster and your opponent activates "Ceasefire" to flip the monster face-up, "Legacy Hunter’s" effect is NOT applied. Also, if "Legacy Hunter" attacks a face-up monster and "Book of Moon" flips it face-down, "Legacy Hunter's" effect DOES apply.



LEGENDARY BLACK BELT


“Legendary Black Belt” inflicts damage based on the original DEF of the destroyed monster (in the Graveyard).

If a monster equipped with “Legendary Black Belt” is destroyed, no damage is inflicted by the effect of “Legendary Black Belt” because it is no longer on the field. This includes if it attacked a monster with equal ATK, for example.

After the monster is sent to the Graveyard after being destroyed as a result of battle, the effect of “Legendary Black Belt” that inflicts effect damage can be chained to.



LEGENDARY FLAME LORD


"Legendary Flame Lord" gets Spell Counters when Spell Cards resolve, not when they are activated.

If you activate a Spell Card, and your opponent chains "Call of the Haunted" to Special Summon "Legendary Flame Lord", "Legendary Flame Lord" does not get a Spell Counter for that Spell Card because "Legendary Flame Lord" must be face-up on the field when the Spell Card is activated and when it resolves in order to get a Spell Counter.



LEGENDARY JUJITSU MASTER


If "Legendary Jujitsu Master" is destroyed, removed from play, or flipped face-down by the effect of the monster he battles with, "Legendary Jujitsu Master"'s effect is still applied and the monster is returned to the top of the Deck.

If "Legendary Jujitsu Master" is changed to a Fiend-Type or a Zombie-Type by "DNA Surgery" and is attacked by "Getsu Fuhma", "Getsu Fuhma"'s effect is Step 1 of a chain because the turn player is Step 1, and "Legendary Jujitsu Master" is Step 2. "Legendary Jujitsu Master" resolves first and "Getsu Fuhma" is sent back to the top of the Deck, then "Getsu Fuhma"'s effect resolves and "Legendary Jujitsu Master" is destroyed.

If you have "Destruction Punch"'s effect, and your opponent attacks your "Legendary Jujitsu Master", you resolve the 2 effects in a chain with the controller (the defending player) choosing the order.



LEKUNGA


You cannot activate "Lekunga"'s effect if you do not have a vacant Monster Card Zone on your side of the field.



LESSER FIEND


Monsters destroyed by this card as a result of battle are not sent to the Graveyard, so "Sangan" or "Mystic Tomato" would not have their effects activated, and the effect of "Kycoo the Ghost Destroyer" will not prevent them from being removed from play.

This card does not negate the effects of monsters it destroys as a result of battle, so a Flip Effect like "Cyber Jar" or Trigger Effect like "D.D. Warrior Lady" will still be activated. "Cyber Jar" would still be removed from play in this example, since damage calculation occurs normally.

If "Lesser Fiend" battles with "Relinquished" equipped with a Monster Card, and that equipped card is destroyed instead of "Relinquished", it is not removed from play since it is the effect of "Relinquished" that destroyed it and not as a result of battle with "Lesser Fiend".



LEVEL CONVERSION LAB


When you resolve the effect of “Level Conversion Lab”, show the card to your opponent then roll the die.

The Level of a monster can go up or down with “Level Conversion Lab”.

If “Cost Down” resolves and lowers the Levels of monsters in your hand, then you use “Level Conversion Lab”, the effect of “Level Conversion Lab” overwrites the effect of “Cost Down”. But if you resolve “Level Conversion Lab” first, and then activate and resolve “Cost Down”, “Cost Down” will lower whatever the result was from ”Level Conversion Lab”.

If you activate “Level Conversion Lab” and change “Levia-Dragon Daedalus” to a Level 5 monster, and “A Legendary Ocean” is on the field, then “Levia-Dragon Daedalus” is Level 4.

If you use “Level Conversion Lab” to change “The Masked Beast” to Level 3, you still need to Tribute 8 Levels worth of monsters for “Curse of the Masked Beast” or "Contract with the Abyss".

The Level change from “Level Conversion Lab” lasts until the end of the turn, even if the monster is Summoned. So if you change “Summoned Skull” to Level 3, and Summon it, it can attack even if “Gravity Bind” is active.



LEVEL LIMIT - AREA B


The effect of "Level Limit - Area B" does not use the chain, it is a continuous effect.

All Level 4 or higher monsters face-up on the field after "Level Limit - Area B" resolves will be in Defense Position. You can change the Battle Position of a Level 4 or higher monster, but it will immediately be changed back to Defense Position because of "Level Limit - Area B"'s effect.

If "Level Limit - Area B" is activated while "Final Attack Orders" is active, then the most recently resolved effect takes precedence and monsters Level 4 or higher will be in Defense Position.

If you Summon “Spell Canceller” while “Level Limit - Area B” is on the field, “Spell Canceller” negates its effect and is not changed to Defense Position.



LEVEL UP!


Sending a monster to the Graveyard is a cost for "Level Up!"



LEVIA-DRAGON - DAEDALUS


You can send "A Legendary Ocean" to the Graveyard to activate "Levia-Dragon Daedalus"' effect, but you can't send "Maiden of the Aqua".

You can't send a face-down "Umi" or "A Legendary Ocean" to activate "Levia-Dragon Daedalus"' effect.

If you activate "Levia-Dragon Daedalus"' effect and your opponent chains "Ring of Destruction" to destroy "Levia-Dragon Daedalus", "Levia-Dragon Daedalus"' effect still resolves even though it has been destroyed.

When "Book of Moon" is chained to "Levia-Dragon Daedalus"' effect to flip it face-down, the effect still resolves, but "Levia-Dragon Daedalus" is destroyed by its own effect, since it's no longer "this card", it's just "a card".



LIFE ABSORBING MACHINE


"The total Life Points you paid" is defined as the Life Points paid for costs (both activation costs and maintenance costs) of cards. It does not include damage or loss of Life Points. Damage is not included even if the damage was caused by an effect you control, such as if you activate "Ring of Destruction".

"In your last turn" is defined as the period from the start of your previous turn’s Draw Phase to the end of that turn’s End Phase. Cost that you paid during your opponent’s turn that occurred between your last turn and the current turn are not included.

The effect of "Life Absorbing Machine" increases your Life Points for each cost you paid separately. So if you had "Fire Princess" on the field, and you paid 2 costs during your last turn, "Fire Princess" will deal 1000 points of damage to the opponent.

"Life Absorbing Machine" does not have to be active at the time the Life Points were paid. If you pay a cost of 2000 Life Points during your turn, then activate "Life Absorbing Machine" during your opponent’s turn, the effect of "Life Absorbing Machine" will increase your Life Points by 1000 during your Standby Phase.

Example: It is your turn. During your Standby Phase you pay 500 Life Points for your "Terrorking Archfiend". During your Main Phase 1 you activate "Life Absorbing Machine". Then you activate "Delinquent Duo" and pay 1000 Life Points for its cost. You Set "Seven Tools of the Bandit" and end your turn. During your opponent’s turn they activate "Reinforcements" and you chain "Seven Tools of the Bandit" to negate and destroy it. Your opponent ends their turn. During your Standby Phase the effect of "Life Absorbing Machine" increases your Life Points by 250 (half of "Terrorking Archfiend"’s cost) then again by 500 (half of "Delinquent Duo"’s cost).

If you have two copies of "Life Absorbing Machine" on the field, their effects are cumulative.



LIGHT OF INTERVENTION


You can activate (flip face-up) this card at any time; it does not need to be activated in response to a Summon.

The effect of this card applies to both players, and does not affect monsters that are already on the field face-down. These monsters remain face-down until flipped face-up as normal. 

While this card is on the field, monsters can be Normal Summoned in face-up Defense Position, and can be the target of "Trap Hole" and will trigger effects like the effect of "Mysterious Puppeteer".

While this card is on the field, if a monster would be Special Summoned in face-down Defense Position (such as with "Cyber Jar" or "Nimble Momonga"), it is instead Special Summoned in face-up Defense Position.

While this card is on the field you cannot flip a monster face-down with "Book of Moon", "Darkness Approaches", etc.



LIGHT OF JUDGMENT


"Light of Judgment" does NOT target. You select the card when "Light of Judgment"'s effect resolves.

You can look at your opponent's hand when you resolve "Light of Judgment"'s effect.

If your opponent chains "Mystical Space Typhoon" to "Light of Judgment" and destroys "The Sanctuary in the Sky", the effect of "Light of Judgment" is still applied.



LIGHTEN THE LOAD


When you activate the effect of "Lighten the Load", your opponent gets to see the Level 7 or higher monster you add to your Deck.



LIGHTNING BLADE


If the equipped monster’s Type is changed into something besides Warrior-Type by "DNA Surgery" or "Scroll of Bewitchment", "Lightning Blade" will be destroyed.

If two copies of this card are equipped to a single monster, that monster’s ATK will increase by 1600 points, and the ATK of all WATER monsters will decrease by 1000 points.



LITTLE-WINGUARD


"Little-Winguard"'s effect can be chained to.

Effects like "Spellbinding Circle" do not prevent you from using "Little-Winguard"'s effect.



LONE WOLF


If you activate “Lone Wolf” targeting an appropriate monster, and later you Summon another monster, the effect of “Lone Wolf” is still applied.

If you target “Monk Fighter”, etc. with “Lone Wolf”, and “Monk Fighter” is later flipped face-down, the effect of “Lone Wolf” disappears and is not re-activated even if “Monk Fighter” is later flipped face-up again.

“Your opponent’s monster effects” on “Lone Wolf” means “the effects of monsters that your opponent controls”. So if your opponent uses “Monster Reborn” on your “Exiled Force”, they still cannot Tribute “Exiled Force” to destroy your “Monk Fighter” targeted by “Lone Wolf”.

If you Summon “Monk Fighter” and target it with “Lone Wolf”, and your opponent controls “Bug-Tusked Mammoth”, you can still attack that same turn with “Monk Fighter”.

If your “Master Monk” targeted with “Lone Wolf” attacks and destroys “D.D. Assailant”, “D.D. Assailant” is removed from play but “Master Monk” is not.

If your opponent Summons “Dark Jeroid” and reduces your “Monk Fighter” ATK by 800 points, then later you activate “Lone Wolf” targeting the “Monk Fighter”, it does not restore the ATK of “Monk Fighter”.

Your “Monk Fighter” targeted by “Lone Wolf” cannot be destroyed by the effect of “Tribe-Infecting Virus”. Furthermore, if it is the only monster on your side of the field, your opponent cannot discard cards to activate “Tribe-Infecting Virus” to destroy Rock-Type monsters, because it will have no effect.

If you have “Monk Fighter” targeted by “Lone Wolf”, the following are examples of monster effects that will NOT be negated because they are not applied to a monster: “Airknight Parshath” (damage is inflicted and a card is drawn), “Fiber Jar” (“Monk Fighter” is shuffled into the Deck), “Maju Garzett” (the ATK of “Maju Garzett” does not become 0), “Susa Soldier” (the damage to Life Points is still halved), “Dark Magician Girl” (her ATK is still increased by her effect), “Stone Statue of the Aztecs” (Battle Damage to your Life Points is doubled), “Amazoness Fighter” (opponent’s Battle Damage to their Life Points is still zero), “Amazoness Swords Woman” (Battle Damage is still redirected), and “Reflect Bounder” (you still take effect damage to your Life Points).

“Archfiend of Gilfer” and “Dark Necrofear” in the Graveyard can activate their effects and target “Monk Fighter” targeted by “Lone Wolf”. This is because they activate as Monster Cards, equip to the target monster, become treated as Equip Spell Cards, and THEN apply their effects (by which point they are now treated as Equip Spell Cards).

The effect of “Lone Wolf” will be negated by Jinzo even if targeting “Monk Fighter”.



LORD OF D.


"Lord of D." cannot negate effects; he only prevents Dragon-Type monsters from being selected as targets of effects. Once a target has been selected, the effect of "Lord of D." is irrelevant.

If your opponent activates "Ring of Destruction" targeting your "Lord of D." and you chain "D. Tribe" to change "Lord of D." to Dragon-Type, "Ring of Destruction" will still resolve and destroy "Lord of D." since he was selected as a target before he was changed into Dragon-Type. If your opponent activates "Ring of Destruction" targeting a Dragon-Type monster you control and you chain "Call of the Haunted" to Special Summon "Lord of D." from your Graveyard, your Dragon-Type monster is still destroyed for the same reason.

If you have "Lord of D." on the field, and activate "Premature Burial" to Special Summon a Dragon-Type monster from your Graveyard, that is okay, but if your opponent later destroys "Premature Burial" your Dragon-Type monster is also destroyed because "Premature Burial" is NOT selecting your Dragon-Type as a target.

While you have "Lord of D." on the field you cannot equip your Dragon-Type monsters with Equip Spell Cards, but if you already have a Dragon-Type monster equipped with an Equip Spell Card when you Summon "Lord of D.", the Equip Spell card is not destroyed or negated, because "Lord of D." only prevents Dragon-Type monsters from being selected as a target.

"Lord of D." will NOT stop "Dark Hole", "Mirror Force", "Raigeki", "Fissure", "Smashing Ground", "Hammer Shot", or "Amazoness Archers", nor will he protect your Dragon-Type monsters from their effects, since these cards affect the whole field and do not select targets.



LORD POISON


No card called "Lord Poison" can be Special Summoned by "Lord Poison"'s effect; either the one that was destroyed and sent to the Graveyard as a result of battle, or another copy of "Lord Poison" that was already in the Graveyard.



LOST GUARDIAN


Whenever the number of your monsters removed from play changes, re-calculate the DEF of “Lost Guardian”. (Just like “Shadow Ghoul”, etc.)

NOTE: When a monster is removed from play, it goes to a “removed zone” (for lack of a better term) of the original owner. If the opponent controlled it, it will return to the opponent’s side of the field when it returns to player, however it is considered to be in the original owner’s “removed zone” while out of play. This is important for effects such as “Lost Guardian”.

Example: Player A controls 2 monsters. Player B activates “Change of Heart” to take control of one of them, then activates “Different Dimension Gate” to remove both from play. Both monsters are in Player A’s “removed zone” while removed from play (so Player A’s “Lost Guardian” would have 1400 DEF). When “Different Dimension Gate” is destroyed, the monster Player B took control of will return to Player B’s side of the field (if possible, if not it is destroyed) before returning to Player A’s side of the field.

Monsters removed from play and kept face-down, like with “Different Dimension Capsule” or “Lightforce Sword”, do NOT count towards the DEF of “Lost Guardian”.



LUMINOUS SOLDIER


If the ATK of "Luminous Soldier" is reduced to 0 because of the effect of "Fairy Box" the ATK will increase by 500 points in the Damage Step if it is battling with a DARK monster.

If the attack target of "Luminous Soldier" is redirected to a DARK monster by the effect of "Dreamsprite" the ATK of "Luminous Soldier" will then increase by 500 points.



MACHINE DUPLICATION


If a monster on the field, with an ATK of 500 or less, is changed to Machine-Type with "DNA Surgery", you can use "Machine Duplication" to Special Summon up to 2 copies of it from your Deck.

The Machine-Type monster is chosen at activation of this card, so if the opponent chains "Ring of Destruction" to destroy the chosen monster, up to 2 copies of that card can still be Special Summoned.



MAGE POWER


"Mage Power" includes itself, Field Spell Cards on your side of the field, and monsters acting like Equip Spell Cards, such as Union Monsters.

If you control "Cannon Soldier" equipped with "Mage Power", and you activate "Limiter Removal", then the ATK of "Cannon Soldier" is (1400 + 500 + 500) x 2 = 4800.



MAGIC CYLINDER


The effect of "Magic Cylinder" negates the attack of one attacking monster, but that monster is still considered to have attacked and may not attack again or have its Battle Position manually changed.

Monsters that may attack twice during the Battle Phase, such as "Hayabusa Knight", that have their first attack negated by the effect of "Magic Cylinder" may still make a second attack.

If the attack of "Goblin Attack Force" or "Spear Dragon" is negated by the effect of "Magic Cylinder", they will not be changed to Defense Position, since Damage Calculation never occurred.

The Damage caused by this card’s effect is equal to the current ATK of the attacking monster.

If an effect is chained to "Magic Cylinder" that destroys the attacking monster, or removes the attacking monster from the turn player’s side of the field (including switching it to your control, or sending it to the owner’s hand), no damage is dealt by the effect of "Magic Cylinder".



MAGIC REFLECTOR


You can put 2 or more counters on a Spell Card if you activate 2 or more "Magic Reflectors". When the Spell Card is destroyed, remove the counters on it 1-by-1.

You can activate "Magic Reflector" and put a counter on a Monster Card equipped to "Relinquished", and if the equipped card would be destroyed, remove 1 counter instead.

If "Imperial Order" is active, and if a Spell Card with a counter on it would be destroyed, the counter is removed instead. "Imperial Order" does not negate the function of counters created by the effect of "Magic Reflector".

If a Spell Card with a maintenance cost has a counter on it, such as "Messenger of Peace", and you choose not to pay the cost, the Spell Card is still destroyed.

If a Field Spell Card has a counter on it and a player activates a new Field Spell Card, the Field Spell Card with the counter is still destroyed.

If "Swords of Revealing Light" has a counter on it, it is still destroyed at the end of the opponent’s third turn after it was activated.

If you use "Magic Reflector" to place a counter on a Union Monster that is an Equip Card, and the Union Monster would be destroyed instead of the equipped monster, remove the "Magic Reflector" counter from the Union Monster instead, and the Union Monster is not destroyed.



MAGICAL EXPLOSION


Count the number of Spell Cards in the Graveyard at the time “Magical Explosion” resolves.



MAGICAL MARIONETTE


There is no limit to the number of Spell Counters you can have on "Magical Marionette".

Removing Spell Counters from "Magical Marionette" to use its effect is a cost.

You can use "Magical Marionette"'s effect multiple times in the same turn, as long as you have enough Spell Counters to pay the cost.

You can destroy "Magical Marionette" with its own effect.

If you activate a Spell Card, and your opponent chains "Call of the Haunted" to Special Summon "Magical Marionette", "Magical Marionette" does not get a Spell Counter for that Spell Card because "Magical Marionette" must be face-up on the field when the Spell Card is activated and when it resolves in order to get a Spell Counter.



MAGICAL MERCHANT


You need to show the cards to your opponent, including the one you keep.

If you pick up your entire Deck and there were no Spell or Trap Cards, then "Magical Merchant"'s effect disappears.



MAGICAL PLANT MANDRAGOLA


Includes your opponent's cards that are capable of having Spell Counters placed on them.



MAGICAL SCIENTIST


You can use "Magical Scientist"'s effect multiple times in the same turn.

"Magical Scientist"'s effect does not target.

If the Fusion Monster is flipped face-down with "Book of Moon", or removed from play with "Dimensionhole" or "Interdimensional Matter Transporter" or "Different Dimension Gate", the effect is reset and the Fusion Monster does not go back to the Fusion Deck, and is not prohibited from attacking your opponent's Life Points directly.

If you Special Summon "Reaper on the Nightmare" with "Magical Scientist", it cannot attack your opponent's Life Points directly (but can attack a monster).

You cannot activate "Secret Pass to the Treasures" targeting a Fusion Monster Special Summoned with "Magical Scientist" because it cannot attack your opponent's Life Points directly that turn.

If "Skill Drain" is activated after a Fusion Monster is Special Summoned with "Magical Scientist", the effect of "Magical Scientist" (that makes the Fusion Monster unable to attack directly and have to go back to the Fusion Deck) has been applied already, and is not negated, so the Special Summoned Fusion Monster still cannot attack directly and must go back to the Fusion Deck.

If "Jowgen the Spiritualist" is on the field, you cannot activate the effect of "Magical Scientist" (so you cannot even pay the cost to try and activate "Last Turn", for example).



MAGICAL THORN


If you have two copies of "Magical Thorn" active on the field, your opponent will take 1000 points of damage whenever they discard a card. If you have three copies, they will take 1500 points of damage.

The effect of "Magical Thorn" is applied when the opponent discards during the End Phase to make their hand size 6, discarding for the cost of cards such as "Tribute to the Doomed", "Cost Down", or "Judgment of Anubis", and discarding for card effects such as "Delinquent Duo", "Confiscation", "Robbin’ Goblin", "Morphing Jar" and "Mefist the Infernal General".

The effect of "Magical Thorn" is NOT applied when you send cards from your hand to the Graveyard for things such as a Tribute for a Ritual Spell Card, a Fusion Material Monster, or the effects of cards like "Chosen One" or "Gravekeeper’s Watcher".

The effect of "Magical Thorn" is NOT applied when cards in your hand are destroyed by "Chain Destruction" or when cards are sent from the Deck to Graveyard by the effect of "Painful Choice". It is also NOT applied when cards in your hand are removed from play by the effect of "Lightforce Sword".

The effect of "Magical Thorn" is only applied when a card is discarded from your opponent’s hand to your opponent’s Graveyard. So if they have your card in your hand by the effect of "Exchange" or "Graverobber" and they discard it, they do not take any damage from the effect of "Magical Thorn".

If the opponent discards from their hand as a cost to activate a card like "Cost Down" and you chain "Magical Thorn" they will not take any damage. If your opponent activates a card where discarding is part of the effect of the card, such as "Card Destruction", and you chain "Magical Thorn", they WILL take damage because the effect of "Magical Thorn" will be active before the discarding effect resolves.

"Magical Thorn" deals damage per card, so if the opponent activates "Graceful Charity" they will take 1000 points of damage when they discard 2 cards. If they discard 5 cards to activate "Final Destiny" they take 2500 points of damage.

Even though "Magical Thorn" does damage per card discarded, it deals the damage as one lump sum for effects like "Dark Room of Nightmare".

"Necrovalley" does not negate the effect of "Magical Thorn".

The effect of "Magical Thorn" inflicts damage after an effect resolves. So if the effect of "Morphing Jar" is activated, the damage will be dealt after the new cards are drawn. This means if your opponent has 100 Life Points, and you have "Magical Thorn" active on the field but only one card left in your Deck, you will lose the Duel before the effect of "Magical Thorn" can deal damage to reduce your opponent’s Life Points to 0.

"Magical Thorn" will deal damage between steps in a chain. For example, both you and your opponent have 100 Life Points remaining, your opponent has two cards in their hand and you have "Magical Thorn" active on the field and a Set "Mind Crush". It is your opponent’s turn and they activate "Final Flame" to deal 600 points of damage to you, and you chain "Mind Crush" calling the "Sinister Serpent" you know they have in their hand. After Step 2 ("Mind Crush") resolves, the effect of "Magical Thorn" deals 500 points of damage to your opponent and you win the Duel before Step 1, "Final Flame", resolves.



MAHARAGHI


If two copies of "Maharaghi" had their effects activated, you resolve them one at a time. This means you look at 1 card, and if you place it back on top of your Deck, you will see it again for the second effect.



MAIDEN OF THE AQUA


The effect of "Maiden of the Aqua" is active only when there is no face-up Field Spell Card on the field. When a Field Spell Card is activated after "Maiden of the Aqua" is Summoned, the effect of "Maiden of the Aqua" is negated as long as there is a face-up Field Spell Card. If the only Field Spell Card is face-down, the effect of "Maiden of the Aqua" is active. If there is a face-up Field Spell Card but it is negated by "Imperial Order", the effect of "Maiden of the Aqua" is not active.

If a Field Spell Card is already active, and "Maiden of the Aqua" is Summoned, the existing Field Spell Card continues to function and "Maiden of the Aqua"’s effect is not applied until there is no face-up Field Spell Card.

While "Maiden of the Aqua" is making the field "Umi", you can activate "Tornado Wall" but if "Maiden of the Aqua" is destroyed, "Tornado Wall" is also destroyed.

If "Maiden of the Aqua", "Umi", and "Tornado Wall" are all on your side of the field, and "Umi" is destroyed, "Tornado Wall" is not destroyed because "Maiden of the Aqua" treats the field as "Umi" as soon as "Umi" leaves play.

If you have "Maiden of the Aqua" (with her effect active) and "The Legendary Fisherman" or "Deepsea Warrior" on your side of the field, and "Dark Hole" is activated, "The Legendary Fisherman" and "Deepsea Warrior" will not be destroyed.

If you have "Maiden of the Aqua" and "Tornado Wall" on the field, and "Maiden of the Aqua" is attacked by "Dark Driceratops" and Battle Damage would be inflicted, "Tornado Wall" still prevents the damage during damage calculation, as "Maiden of the Aqua" will remain on the field until the end of the Damage Step.



MAJI-GIRE PANDA


The effect of “Maji-Gire Panda” is a Trigger Effect that activates when 1 or more Beast-Type monster(s) are destroyed. If the monsters were destroyed as a result of battle, the timing of this effect is at the end of the Damage Step, when the monsters are sent to the Graveyard.

You can chain to the activation of “Maji-Gire Panda”’s effect, including with “Divine Wrath”.

If 2 or more Beast-Type monsters are destroyed at the same time, the ATK of “Maji-Gire Panda” only increases by 500 points.

Beast-Type tokens like “Sheep Tokens” are included and will increase the ATK of “Maji-Gire Panda” when destroyed.

Monsters changed to Beast-Type by “DNA Surgery” are included and will increase the ATK of “Maji-Gire Panda” when destroyed.

Beast-Type monsters on your opponent’s side of the field are included and will increase the ATK of “Maji-Gire Panda” when destroyed.

When face-down Beast-Type monsters are destroyed (by a card effect), the ATK of “Maji-Gire Panda” does not increase.

The ATK increase from the effect of “Maji-Gire Panda” remains as long as “Maji-Gire Panda” remains face-up on the field.




MAJU GARZETT


You can't search for "Maju Garzett" with "Sangan" or "Mystic Tomato".

You can Tribute face-down monsters for "Maju Garzett" and their ATK will count towards "Maju Garzett"'s ATK.

"Maju Garzett"'s ATK will be 0 if you Special Summon it, or Tribute Summon it with a monster with "?" ATK (such as "Gradius' Option" or another "Maju Garzett"), or Tribute Summon it with only 1 Tribute using "Cost Down", or equip it with "Megamorph", or if it's flipped face-down and then face-up again, or if you Tribute Summon it with Mirage Tokens, or if you remove it from play with "Dimensionhole" and it returns to the field.

If "Skill Drain" is active, "Maju Garzett"'s ATK is reset to 0 even if "Skill Drain" is later destroyed.

If "Maju Garzett" battles "Cat's Ear Tribe", its original ATK is changed to 200 for the battle, then after the battle its ATK is reset to 0.

When you Tribute Monster Tokens to Tribute Summon "Maju Garzett", the sum of their ATK's will be the ATK of "Maju Garzett".

When you Tribute Summon "Maju Garzett", your opponent can use "Trap Hole" or "Bottomless Trap Hole" if appropriate.



MAKYURA THE DESTRUCTOR


This card's effect is a Continuous Effect.

You cannot activate a "Raigeki Break" in your hand by discard "Makyura the Destructor" as a cost.



MALEVOLENT NUZZLER


If a "Sangan" or a "Witch of the Black Forest" equipped with "Malevolent Nuzzler" is Tributed and you activate the effect of "Malevolent Nuzzler", "Malevolent Nuzzler" goes on top of your Deck and then "Sangan" or "Witch of the Black Forest" is resolved. If "Sangan" is destroyed (not Tributed) the effects of "Sangan" and "Malevolent Nuzzler" are simultaneous and form a chain.



MALICE DOLL OF DEMISE


If your opponent takes control of your "Malice Doll of Demise", and sends it to the Graveyard by the effect of a Continuous Spell Card, you can still activate its effect to Special Summon it during your Standby Phase.

If "Malice Doll of Demise" is Tributed to activate the effect of "Mass Driver", then "Malice Doll of Demise’s" effect does not activate because the Tribute is treated as a cost, not an effect.

Examples of Continuous Spell Cards that would send "Malice Doll of Demise" from the field to the Graveyard by their effect include "Ectoplasmer" and "Continuous Destruction Punch".

You can only activate the Special Summoning effect of “Malice Doll of Demise” during your first Standby Phase after it was sent to the Graveyard by the effect of a Continuous Spell Card. If you miss that, you cannot then activate the Special Summoning effect later on. If there is no monster card zone at the appropriate time, the effect is activated but you cannot Special Summon the “Malice Doll of Demise”, so its effect disappears.

The effect of "Malice Doll of Demise" activates in the Graveyard. If "The End of Anubis" is on the field during the Standby Phase in which "Malice Doll of Demise" would activate its effect, then the effect is negated and "Malice Doll of Demise" is not Special Summoned. If "The End of Anubis" leaves play after that, you still cannot activate "Malice Doll of Demise"’s effect because the opportunity has passed.



MAN-EATER BUG


If "Man-Eater Bug" is the only monster on the field when it is flipped, it destroys itself.



MANTICORE OF DARKNESS


"Manticore of Darkness"' effect can be activated during the End Phase when it was sent to the Graveyard from the field, hand, or your Deck that same turn.

When you send 1 "Manticore of Darkness" to the Graveyard to Special Summon another "Manticore of Darkness", you can then send the new "Manticore of Darkness" to the Graveyard to Special Summon the first "Manticore of Darkness".

If "Card of Safe Return" is active, and "Manticore of Darkness" is Special Summoned with its effect, you can draw a card. So with 2 "Manticores of Darkness", 1 of them sent to the Graveyard, and "Card of Safe Return" in play, you can draw as many cards as you want.

When "Manticore of Darkness" is sent to the Graveyard because of hand size adjustment in the End Phase, you can activate its effect.

You can send a face-down Beast, Beast-Warrior, or Winged Beast-Type monster to the Graveyard for "Manticore of Darkness"' effect.

Sending monsters to the Graveyard for "Manticore of Darkness"' effect is a cost.

You can't send a Monster Token to the Graveyard for "Manticore of Darkness"' effect because Monster Tokens are taken off the field instead of going to the Graveyard.

The owner of "Manticore of Darkness" gets the effect, so if your opponent controls your "Manticore of Darkness" and it's sent to the Graveyard, you get to activate the effect.



MARAUDING CAPTAIN


If you have 2 "Maurading Captains" on your side of the field, the opponent cannot attack any face-up Warrior-Type monsters you control. They can attack your Life Points directly if they control a monster with an effect that allows it (Such as "Rainbow Flower", "Inaba White Rabbit", or a Toon Monster). They could also attack a non-Warrior Type monster you control.

Your opponent can attack face-down monsters while you have "Maurading Captain" on the field, even if the face-down monster is Warrior-Type.

If you control "Maurading Captain" and a Warrior-Type monster equipped with "Ring of Magnetism", the opponent must attack the monster equipped with "Ring of Magnetism" if they choose to attack.

If you control 2 "Maurading Captains" and one of them is equipped with "Ring of Magnetism", your opponent cannot attack either one.

If you control "Patrician of Darkness", "Maurading Captain" and a Warrior-Type monster when your opponent attacks, you can use the effect of "Patrician of Darkness" to redirect the attack to "Patrician of Darkness" or "Maurading Captain" only. Not to the other Warrior-Type monster because it cannot be attacked.

The monster Special Summoned by the effect of "Maurading Captain" does NOT have to be a Warrior-Type monster.

If your opponent activates "Torrential Tribute" in response to the Summoning of "Maurading Captain" (by chaining to the Trigger Effect of "Marauding Captain"), all monsters on the field will be destroyed, and then you Special Summon for "Maurading Captain"’s effect. If they wait and activate "Torrential Tribute" in response to the Special Summoning of a monster for the effect of "Marauding Captain", then all monsters will be destroyed including the newly-Special Summoned monster.



MARYOKUTAI


This monster’s effect is multi-trigger, and therefore Spell Speed 2. So it may be used against Quick-Play Spell Cards.

You can Tribute "Maryokutai" to activate its effect during the Battle Phase if it is not attacking or being attacked.



MASK OF BRUTALITY


The payment of 1000 Life Points is optional and the controller of "Mask of Brutality," not the controller of the equipped monster, chooses to pay or not. If you choose not to pay 1000 Life Points, "Mask of Brutality" is destroyed.



MASK OF RESTRICT


Fusion Material Monsters are not Tributes, so a Fusion Monster may be Special Summoned while this card is active on the field.

If "Mask of Restrict" is chained to a Ritual Spell Card, the effect of the Spell Card cannot resolve and no monsters are Tributed from the hand or field.

If "Mask of Restrict" is active, a Toon Monster that requires Tributes cannot be Special Summoned. The activation of "Mask of Restrict" cannot be chained to the Summoning of a Toon Monster, but it can be chained to the activation of "Toon World".

If "Mask of Restrict" is chained to the effect of "Cannon Soldier" you will still take damage because Tributing a monster is a cost of "Cannon Soldier" and is performed when the effect of "Cannon Soldier" is activated. If "Mask of Restrict" is chained to your opponent’s "Share the Pain" you do not have to Tribute a monster, but your opponent still does because it is a cost.



MASKED SORCERER


The effect of "Masked Sorcerer" includes Battle Damage caused when it is attacked in Defense Position by a monster with ATK lower than "Masked Sorcerer"’s DEF.



MASS DRIVER


Tributing a monster for "Mass Driver" is a cost.

You can use "Mass Driver"'s effect repeatedly in the same turn as long as you can keep paying the cost.

The activation of "Mass Driver"'s effect can be chained to.



MATAZA THE ZAPPER


You cannot use "Change of Heart" on a face-up "Mataza the Zapper".

If you take control of a face-down "Mataza the Zapper" and flip it face-up, it stays on your side of the field and doesn't return to the original controller.

If you use "Monster Reborn" on "Mataza the Zapper" while "Remove Brainwashing" is active, control of "Mataza the Zapper" does not return to the original owner.

While "Skill Drain" is active, you can take control of "Mataza the Zapper" from your opponent.



MAZERA DEVILLE


You cannot use "Monster Reborn", etc. on "Mazera DeVille" even if he is Special Summoned properly, because he "cannot be Special Summoned, EXCEPT by...".

If you Special Summon "Mazera DeVille", his effect activates, and your opponent chains "Mystical Space Typhoon" to destroy "Pandemonium" in a chain, "Mazera Deville"'s effect disappears because his effect needs "Pandemonium" on the field when the effect resolves, not just when it activates (just like "The Agent of Judgment - Saturn").

If your opponent has less than 3 cards in his hand, he must discard his entire hand.



MECHA-DOG MARRON


If “Mecha-Dog Marron” is destroyed in the middle of a chain, its effect starts a new chain when the current chain has finished resolving.

You can use “Barrel Behind the Door” against either effect of “Mecha-Dog Marron”.




MECHANICAL HOUND


“Activate” means make the card face-up, or activate it from your hand. If “Mechanical Hound” is face-up on the field, your opponent can still use the effects of Continuous Spell Cards that are already face-up on the field.



MEGA TON MAGICAL CANNON


Removing Spell Counters is a cost. If you do not have 10 Spell Counters you cannot activate "Mega-Ton Magical Cannon".



MEGAMORPH


"Megamorph" changes the original ATK of the monster it is equipped to. Having multiple "Megamorphs" equipped to a monster is the same as having one.

"Megamorph" is always recalculating with every change in Life Points. For example, your "Jirai Gumo" is equipped with "Megamorph" and you have 8000 Life Points compared to your 7000. You declare an attack with "Jirai Gumo" and lose the coin toss, losing 4000 Life Points. Now "Jirai Gumo"’s ATK is doubled before Damage Calculation.

When Life Points are equal the equipped monster’s ATK is unchanged.

You may equip "Megamorph" to your opponent’s monster, but ‘your Life Points’ refers to the controller of "Megamorph". So if you have more Life Points than your opponent, your opponent’s monster equipped with "Megamorph" has its ATK halved.



MEGAROCK DRAGON


You must remove from play at least 1 Rock-Type monster in your Graveyard in order to Special Summon “Megarock Dragon”.

The original ATK of “Megarock Dragon” is determined by its effect. This is further doubled/halved by “Megamorph” and other effects that are based off of original ATK. So if you Special Summon “Megarock Dragon” with an original ATK of 2100 points, then equip it with “Megamorph”, its ATK will be 4200 or 1050 depending on your Life Points.

If “Skill Drain” is active while “Megarock Dragon” is in play, the effect of “Megarock Dragon” is negated and its original ATK and DEF are treated as zero. Even if “Skill Drain” is destroyed later, the original ATK and DEF of “Megarock Dragon” will remain zero.

If “Megarock Dragon” is flipped face-down, or removed from play, or sent to the Graveyard, its effect is wiped and its original ATK and DEF are zero.



MERMAID KNIGHT


"Mermaid Knight" can attack twice if "Maiden of the Aqua" is making the field treated as "Umi".

If you declare your second attack with "Mermaid Knight", and "Umi" is destroyed during the Battle Step, a replay occurs and you cannot attack a second time with "Mermaid Knight".

If there is no "Umi" on the field and "Mermaid Knight" attacks, then you Special Summon "Maiden of the Aqua" to treat the field as "Umi", you can attack a second time.



MESSENGER OF PEACE


The maintenance cost is optional, you may chose not to play 100 Life Points and "Messenger of Peace" will be destroyed.

The ATK of an attacking monster may increase above 1500 after the attack is declared.



METALLIZING PARASITE - LUNATITE


While "Metallizing Parasite - Lunatite" is equipped to a monster, and "Final Destiny" is activated, all monsters are destroyed except for the monster equipped with "Metallizing Parasite - Lunatite".

If you equip "Metallizing Parasite - Lunatite" to a monster that has been affected by "Limiter Removal", the monster is still destroyed during the End Phase by "Limiter Removal"'s effect.



METALMORPH


If you equip two copies of "Metalmorph" to a single monster, its ATK and DEF will be increase by 600 and the second effect will add half of your attack target’s ATK to the equipped monster’s ATK twice.

The second effect of this card only increases the equipped monster’s ATK when it is the attacking monster (during your Battle Phase) not when it is being attacked during your opponent’s Battle Phase.

If "Reverse Trap" is activated, a monster equipped with "Metalmorph" will have its ATK and DEF decreased by 300 points, but the second effect of "Metalmorph" will be unaffected and still increase the equipped monster’s ATK by an amount equal to half of the attacked monster’s ATK.



METALSILVER ARMOR


Your opponent cannot activate "Monster Reborn" and other cards that target while you have a monster equipped with "Metalsilver Armor". Your opponent can activate "Raigeki", "Mirror Force", and other cards that do not target.

If you attack with "Dark Magician", and you control another monster equipped with "Metalsilver Armor", your opponent cannot activate "Magic Cylinder" because "Magic Cylinder" targets and only the monster equipped with "Metalsilver Armor" can be targeted (and it is not attacking).

If you have "Metalsilver Armor" active, your opponent cannot target his/her monsters either (with Equip Spell Cards, etc.), including with "Premature Burial".

If you have 2 monsters equipped with "Metalsilver Armor", your opponent cannot activate any effects that target 1 monster.

When you have a monster equipped with "Metalsilver Armor", your opponent CAN activate the effect of "Nimble Momonga" or "Giant Germ" because their effects do not target 1 card.

When you have a monster equipped with "Metalsilver Armor", your opponent CAN activate "Reinforcement of the Army".

When you have a monster equipped with "Metalsilver Armor", your opponent CAN activate the effect of "The Thing in the Crater" because it Special Summons a monster from your HAND.



METAMORPHOSIS


Metamorphosis does not properly Summon a Fusion Monster, so you cannot use "Monster Reborn" on it afterwards.

Tributing a monster is a cost.

You can Tribute a face-down monster.

If you activated “Soul Exchange” targeting your opponent’s monster, if the monster is face-down, you cannot Tribute it as a cost for “Metamorphosis”.

You can Tribute a Monster Token (including a Sheep Token from "Scapegoat").

If there is no monster with the same level as the Tributed monster in your Fusion Deck, then you cannot activate this card.

"Metamorphosis" vs. "A Legendary Ocean": if you want to Special Summon a Level 6 Fusion Monster from your Fusion Deck, you have to Tribute a Level 7 WATER monster on the field because it is treated as a Level 6.



METEOR OF DESTRUCTION


If you activate “Meteor of Destruction”, and an effect is chained that causes your opponent’s Life Points to fall below 3000, “Meteor of Destruction” was already activated properly, so it resolves as normal.



METEORAIN


You can activate "Meteorain" during your turn at any point from the Draw Phase to the end of your Battle Phase; you cannot activate it during the Damage Step, Main Phase 2, your End Phase, or your opponent's turn.

"Meteorain"'s effect applies to all your monsters. Monsters that you Summon, Flip Summon, Special Summon, etc. after activating "Meteorain" still get its effect.

When you attack with a monster that has "Meteorain"'s bonus, and you attack a Defense Position "Amazoness Swordswoman", then you will take the Battle Damage to your Life Points.



MICRO RAY


You select the monster when you activate "Micro Ray".

If you apply "Micro Ray"'s effect and then a new card increases the DEF, add the new DEF to the zero.

You can activate "Micro Ray" during the Damage Step.



MID SHIELD GARDNA


The first effect of “Mid-Shield Gardna” is an Ignition Effect. The second is a Trigger Effect. You can chain to these effects. You can activate “Divine Wrath” against these effects.



MILLENNIUM SCORPION


The effect of “Millennium Scorpion” is a Trigger Effect. Each time it destroys a monster on your opponent’s side of the field and sends it to the Graveyard as a result of battle, it activates. This effect can be chained to. You can activate “Divine Wrath” against it.

If “Millennium Scorpion” attacks and destroys a Monster Token, the effect of “Millennium Scorpion” does not activate because a Monster Token isn’t sent to the Graveyard.

If “Millennium Scorpion” has an ATK boost from its effect, but is removed from play with “Interdimensional Matter Transporter”, or flipped face-down, the effect is reset and its ATK returns to normal.



MINAR


If the summoning of "Minar" is negated by "Solemn Judgment", etc. its effect is not activated, as it is not considered to have gone directly from your hand to the Graveyard.



MIND CONTROL


The effect of “Mind Control” that prevents the targeted monster from attacking or being Tributed lasts until the End Phase of the turn ”Mind Control” was activated, even if the monster is flipped face-down before the End Phase. If the monster targeted with this card is flipped face-down, it will still return to the original owner's side of the field during the End Phase.



MIND CRUSH


You cannot activate "Mind Crush" if you have no hand. Both players must have at least 1 card in hand in order to activate "Mind Crush".

You declare the card name when you activate "Mind Crush".

If the opponent doesn’t have the named card, you can check their hand to confirm.



MIND ON AIR


"Mind on Air"’s effect is continuous, so if you Summon "Mind on Air" and your opponent responds with "Trap Hole", your opponent must show their hand until "Mind on Air" is no longer on the field (after "Trap Hole" resolves).

If "Mind on Air" is causing your opponent’s hand to be revealed, and an effect that randomly selects a card is activated (like "Robbin’ Goblin"), your opponent shuffles their hand and you must choose randomly without seeing the fronts of the cards.



MINE GOLEM


The effect of “Mine Golem” is a Trigger Effect that activates when “Mine Golem” is sent to the Graveyard after having been destroyed as a result of battle. It can be chained to.



MINEFIELD ERUPTION


If you activate “Minefield Eruption”, you inflict damage, then send your “Mine Golem”(s) to the Graveyard. So your opponent has missed the timing and cannot activate “Numinous Healer”, etc.

The number of “Mine Golem” cards is considered when “Minefield Eruption” resolves, not when it is activated.



MIRACLE FUSION


If “Kycoo the Ghost Destroyer” is on your opponent’s side of the field, you can activate “Miracle Fusion” if all the Fusion Material Monsters are on the field; however, if any of them are in the Graveyard, you cannot activate it.

“Miracle Fusion” is a card that targets monsters, either on the field and/or in the Graveyard.



MIRACLE RESTORING


Removing 2 Spell Counters is a cost.



MIRAGE DRAGON


The effect of this monster makes the opponent of this monster’s current controller unable to activate Trap Cards during the Battle Phase. If you take control of your opponent’s monster with "Change of Heart" during your turn, your opponent cannot activate Trap Cards during your Battle Phase, but you can.

The effect of this monster makes your opponent unable to activate Set Trap Cards. However, your opponent can still activate the effects of face-up Trap Cards such as "Type Zero Magic Crusher", "Ultimate Offering", "Skull Lair", "The Dragon’s Bead", and "Astral Barrier".



MIRAGE KNIGHT


"Mirage Knight" cannot be Normal Summoned or Set, and cannot be Special Summoned EXCEPT by the effect of "Dark Flare Knight". So "Mirage Knight" cannot be Special Summoned with "Monster Reborn", etc., even if Special Summoned properly first.

"Mirage Knight" can be Special Summoned by "Dark Flare Knight"'s effect even if "Skill Drain" is active, because "Dark Flare Knight"'s effect activates in the Graveyard. However, "Mirage Knight"'s effects are negated by "Skill Drain".

When a "Mirage Knight" that was involved in battle is flipped face-down, it is not removed during the End Phase.

When a "Mirage Knight" that was involved in battle is removed from play with "Interdimensional Matter Transporter" or "Dimensionhole", it is not removed from play during the End Phase by its own effect.



MIRAGE OF NIGHTMARE


If, after drawing during your opponent’s Standby Phase, your "Mirage of Nightmare" is destroyed before you have to discard, then you do not need to discard for its effect.

You may activate "Mystical Space Typhoon" during your Draw Phase to destroy "Mirage of Nightmare" before you have to discard during your Standby Phase. If your Draw Phase was skipped for some reason, you can still activate "Mystical Space Typhoon" to destroy "Mirage of Nightmare" before activating the effect of "Mirage of Nightmare" that will force you to discard. (You can activate any number of effects during your own Standby Phase in any order you wish, as long as required effects are dealt with by the time you leave the Standby Phase and enter your Main Phase 1.)

When the turn player controls "Mirage of Nightmare" and "Imperial Order":
If you draw for "Mirage of Nightmare" during your opponent’s Standby Phase, and then activate "Imperial Order" after that, during your Standby Phase you will have 2 mandatory effects: discarding for "Mirage of Nightmare" and paying 700 Life Points for "Imperial Order" or else destroying it. In this case, you choose which effect to resolve first, and you can choose to resolve "Mirage of Nightmare" first, even though its effect will be negated by "Imperial Order". So you activate its effect, and do not discard. Then you can choose not to pay 700 Life Points to keep "Imperial Order", and "Imperial Order" will be destroyed. Then you can enter Main Phase 1, and you did not have to discard for "Mirage of Nightmare" (because its effect was negated at the time you chose to resolve it).

When the turn player controls "Imperial Order" and the opponent controls "Mirage of Nightmare":
If the opponent controls "Mirage of Nightmare" going into the turn player’s Standby Phase, and the turn player already controls a face-up "Imperial Order", then there are 2 mandatory effects that must be resolved: the turn player must pay 700 Life Points or destroy "Imperial Order", and the opponent must draw cards for "Mirage of Nightmare". The turn player has priority to resolve an effect first. If the turn player passes, priority goes to the opponent. If the opponent also passes, then the turn player must resolve an effect, and must pay for "Imperial Order" or it is destroyed. If he does not pay, and "Imperial Order" is destroyed, then the opponent can draw for "Mirage of Nightmare".

The same procedure is used if both players control "Mirage of Nightmare". Generally, the turn player will first discard for "Mirage of Nightmare", then the opponent will draw for their "Mirage of Nightmare".

If you discard "Sinister Serpent" during your Standby Phase for the effect of "Mirage of Nightmare", you may add "Sinister Serpent" back to your hand during that same Standby Phase.

If you have multiple copies of "Mirage of Nightmare", you don’t draw for more than 1 because you have 4 cards in your hand from using the effect of only 1 of them; nor do you have to discard for the second copy because you didn’t draw any cards using its effect. If you draw so that you have 4 cards using 1 "Mirage of Nightmare", and some effect causes you to discard during that same Standby Phase, you may then activate the other "Mirage of Nightmare" to draw back up to 4; in this case you discard separately for each "Mirage of Nightmare" because you drew with both, and if 1 of them is destroyed you do not have to discard for its effect, only for the effect of the "Mirage of Nightmare" that was not destroyed. 

If you have 4 or more cards in your hand during your opponent’s Standby Phase, do not draw, and do not discard during your next Standby Phase (the effect of "Mirage of Nightmare" is not applied).

If your Standby Phase is skipped because of "Solomon’s Lawbook", etc., do not discard for "Mirage of Nightmare".

Drawing for "Mirage of Nightmare" is considered 1 draw no matter how many cards are drawn, so you only gain 500 Life Points if you have "Solemn Wishes".

If you draw 3 cards for "Mirage of Nightmare", but only have 2 cards in your hand during your next Standby Phase, discard your entire hand (2 cards).



MIRROR WALL


If "Mirror Wall" is already face-up on the field when a monster declares an attack, "Mirror Wall" reduces the ATK of the attacking monster by half when the attack is declared. 

If "Mirror Wall" is activated during an attack (including during the Damage Step), then it reduces the ATK of the attacking monster when "Mirror Wall" resolves. (Even though "Mirror Wall" normally reduces the attack by half when the attack is declared, it will still reduce the attack by half if you activate it after the attack is declared.) 

If "Mirror Wall" halves the ATK of a monster, it remains halved as long as "Mirror Wall" remains face-up on the field. If "Mirror Wall" is removed from the field, the ATK of the monsters is restored. 

If a monster attacks twice (over 2 turns, or if “Black Luster Soldier – Envoy of the Beginning” attacks twice in a row, etc.), its ATK is still only reduced by half once. So “Black Luster Soldier – Envoy of the Beginning” will have 1500 ATK for both of its attacks, for example. 

If you have 2 copies of "Mirror Wall", and a monster attacks, its ATK is one-quarter. So “Blue-Eyes White Dragon” would have 750 ATK, for example. If 1 of the "Mirror Wall" copies leaves play, then the ATK is increased to half (if both copies leave play, the ATK is restored to full.)

You can activate "Mirror Wall" during the Damage Step before damage calculation.

The effect of "Mirror Wall" does not target.

"Reverse Trap" will have no effect on "Mirror Wall".



MOBIUS THE FROST MONARCH


You select the Spell / Trap Cards when you activate the effect of "Mobius the Frost Monarch".

This effect targets.

If "Level Limit - Area B" is active and "Mobius the Frost Monarch" is successfully Tribute Summoned, "Level Limit - Area B" is a Continuous Spell Card so its effect is applied and the battle position of "Mobius the Frost Monarch" is changed to Defense Position. Then you can activate the effect of "Mobius the Frost Monarch".

If "Mobius the Frost Monarch" is Tribute Summoned by the effect of "Ultimate Offering" in the middle of a chain (and is not the last step of the chain to resolve), then you have missed the timing on his effect and you cannot activate his effect to destroy 2 Spell or Trap Cards.

If 1 of the 2 Spell or Trap Cards targeted by the effect of "Mobius the Frost Monarch" is destroyed by some card effect before his effect resolves, the remaining 1 card is still destroyed by his effect.



MOISTURE CREATURE


You can Summon "Moisture Creature" by Tributing 2 monsters, but the effect will not be activated.

You cannot Summon "Moisture Creature" by Tributing 3 monsters if there are no Spell or Trap Cards on your opponent’s side of the field.

If you activate the effect of "Moisture Creature" and your opponent chains "Book of Moon" to the effect, the effect still resolves and all Spell and Trap Cards on your opponent’s side of the field are destroyed.



MOKEY MOKEY KING


When "Mokey Mokey King" that was Special Summoned by "Magical Scientist" is returned to the Fusion Deck, it has been removed from the field so its effect activates and you Special Summon as many "Mokey Mokey" as possible from your Graveyard.

Missing the Timing: If "Mokey Mokey King" leaves the field in the middle of a chain (for example, if destroyed by "Ring of Destruction" chained to "Pot of Greed", or Tributed for a Tribute Summon or for the effect of "Cannon Soldier", etc.,), you miss the timing and you cannot Special Summon. Only when the last action of the chain is the removal of "Mokey Mokey King" from the field, can you activate its effect.



MOKEY MOKEY SMACKDOWN


If the effect of "Mokey Mokey Smackdown" is activated (by a Fairy-Type monster on your side of the field being destroyed), and afterwards you Summon a "Mokey Mokey", that "Mokey Mokey" will also have 3000 ATK even though it wasn’t on the field when the Fairy-Type monster is destroyed.



MOLTEN ZOMBIE


If you Special Summon "Molten Zombie" face-down with "The Shallow Grave", etc., its effect does not activate.

When you Special Summon "Molten Zombie" and you have "Card of Safe Return", either effect can be Step 1 of the chain; your choice.



MONSTER GATE


If you pick up a Spirit Monster, you cannot Special Summon it and it is sent to the Graveyard.

If you pick up a Guardian and don't have the corresponding Equip Spell Card on the field, you cannot Special Summon the Guardian and it is sent to the Graveyard. If you have the corresponding Equip Spell Card, the Guardian is Special Summoned.

If you go through your whole Deck without finding a card to pick up, "Monster Gate"'s effect is negated and the cards you picked up are shuffled back into the Deck.

Your opponent can chain "Royal Oppression"'s effect to negate "Monster Gate"'s effect.

Cards picked up that cannot be Normal Summoned are considered "sent to the Graveyard", not "discarded".

If you Special Summon "Dark Magician of Chaos" with "Monster Gate", the effect of "Dark Magician of Chaos" activates, but it activates after "Monster Gate" has fully resolved and sent other picked up cards to the Graveyard, so you can use "Dark Magician of Chaos"' effect to retrieve a Spell Card that was picked up and sent to the Graveyard by "Monster Gate" in the process of searching for the "Dark Magician of Chaos".



MONSTER REINCARNATION


You can select a card discarded by the effect of "Monster Reincarnation" as a target of the effect of that same "Monster Reincarnation" (returning the monster to your hand).

If you discard "Night Assailant" or "Makyura the Destructor" their effects activate even if you retrieve the same card.



MORALE BOOST


If "Morale Boost" and other Equip Spell Cards are destroyed at the same time with "Harpie's Feather Duster" or "Heavy Storm", "Morale Boost" does not inflict any damage.

While your "Morale Boost" is active, and you activate your opponent's Equip Spell Card that you had because of "Exchange", when that Equip Spell Card is removed from the field it is you that takes the damage.

"Morale Boost"'s effect includes when monsters are equipped to "Relinquished" or "Sword Hunter", and when such equipped monsters are removed from the field.

"Morale Boost"'s effect includes "Kisetai", and Union Monsters equipped to another monster by their own effect, and when such equipped monsters are removed from the field, and when Union Monsters "detach" and become monsters again.

"Morale Boost"'s effect includes when you equip an Equip Spell Card to your opponent's monsters, and when such cards are removed from the field.

"Morale Boost"'s effect includes when you Summon "Guardian Elma" and resolve her effect.

"Morale Boost"'s effect includes when "Tailor of the Fickle" is used.



MORPHING JAR


If there are fewer than 5 cards in the Deck of either player when this card’s Flip Effect is activated, that player will lose the Duel, since the text of this card says "draw".



MOTHER GRIZZLY


If you attack with your "Mother Grizzly" and it is destroyed as a result of battle, you may attack with the monster Special Summoned by "Mother Grizzly" before entering Main Phase 2.

If your opponent controls your "Mother Grizzly" and it is destroyed as a result of battle, you get the effect of "Mother Grizzly" NOT your opponent.

Since the Special Summoning occurs during the Damage Step, "Torrential Tribute", etc. cannot be used.



MUCUS YOLK


Zero damage is not damage, so "Mucus Yolk" must have its ATK increased somehow in order to inflict damage to the opponent and activate its effect.

"Mucus Yolk" can continue to activate its effect over and over again, as long as it keeps inflicting Battle Damage to the opponent.

If "Mucus Yolk" inflicts damage multiple times in the same turn, such as with "Twin Swords of Flashing Light – Tryce", it only increases by 1000 points during your next Standby Phase.



MULTIPLICATION OF ANTS


You can Tribute a face-down Insect-Type monster when you activate "Multiplication of Ants".



MUSTERING OF THE DARK SCORPIONS


If you have 2 copies of "Cliff the Trap Remover" (for example) in your hand, you can Special Summon 1 of them with "Mustering of the Dark Scorpions". You can Special Summon him even if you already have "Cliff the Trap Remover" on your side of the field from before you activated "Mustering of the Dark Scorpions".

You don't have to Special Summon all possible monsters with "Mustering of the Dark Scorpions"; you can keep some in your hand if you want.

If your opponent chains "Ring of Destruction" to "Mustering of the Dark Scorpions" to destroy your "Don Zaloog", "Mustering of the Dark Scorpions" still resolves.



MY BODY AS A SHIELD


"My Body as a Shield" will negate cards such as "Dark Hole", "Fissure", "Raigeki", "Eternal Rest", "Nobleman of Crossout", "Tribute to the Doomed", "Thousand Knives", "Trap Hole", "Two-Pronged Attack", "Mirror Force", "House of Adhesive Tape", "Eatgaboon", "Ring of Destruction", "Torrential Tribute", "Bottomless Trap Hole", "Man-Eater Bug", "Blast Juggler", "Dragon Seeker", "Dream Clown", "Throwstone Unit", "Burst Breath", "Swarm of Scarabs", "Cyber Jar", "Tribe-Infecting Virus", "Raigeki Break", "XYZ Dragon Cannon", "Mega-Ton Magical Cannon", "Exiled Force" (negates the effect but will not destroy "Exiled Force" as it is already in the Graveyard), "Offerings to the Doomed" (negates "Offerings to the Doomed" so you do not skip your Draw Phase), "Jowgen the Spiritualist" (when its effect is activated), "Dragon's Gunfire" (if the effect that destroys a monster is selected), or "The Last Warrior From Another Planet" (negates the effect and destroys "The Last Warrior From Another Planet").

"My Body as a Shield" can only be used against effects that will destroy monsters at that time. So you cannot use "My Body as a Shield" when "Tribe-Infecting Virus" is summoned; you can only use it in response to the activation of "Tribe-Infecting Virus"'s effect, at which point the effect of "Tribe-Infecting Virus" is negated and "Tribe-Infecting Virus" is destroyed. Also, you cannot use "My Body as a Shield" against cards whose effects will not destroy a monster right away, so you cannot use "My Body as a Shield" against "Jigen Bakudan", "Ekibyo Drakmord", "Magical Hats", "Steel Scorpion", "Toon Monsters", "Thunder Nyan Nyan", "Gradius' Option", "Summoner of Illusions", "Limiter Removal", "Call of the Haunted", "Premature Burial", or "Autonomous Action Unit".

You cannot use "My Body as a Shield" against cards whose effects might or might not destroy a monster right away, such as "Earthshaker", "Barrel Dragon", "Acid Trap Hole", or "Time Wizard".

You cannot use "My Body as a Shield" against monsters with continuous effects such as "Kotodama" .

You cannot activate "My Body as a Shield" during the Damage Step, so you cannot use it against a "Man-Eater Bug" or "Cyber Jar" flipped by an attack, but you can use it when these monsters are Flip Summoned.

"Judgment of Anubis" may be chained to "My Body as a Shield".



MYSTERIOUS PUPPETEER


When you have "Mysterious Puppeteer" face-up on the field, if you Summon a monster and you opponent activates "Trap Hole" your monster is destroyed and you still gain 500 Life Points, since the monster was Summoned and then destroyed.



MYSTIC SWORDSMAN LV2


If "Mystic Swordsman LV2" attacks a face-down Defense Position monster, that monster is destroyed by "Mystic Swordsman LV2"’s effect, not as a result of battle. So you cannot use its second effect to Special Summon "Mystic Swordsman LV4" during the End Phase.

If a level monster fulfills its condition to Special Summon the next-highest level (for example, if "Armed Dragon LV5" destroys a monster as a result of battle), and the level monster is then flipped face-down, or removed from play permanently, or sent to the Graveyard and then Special Summoned from the Graveyard, then its condition is reset and it is no longer considered to have met the condition to level up to the next level.



MYSTIC SWORDSMAN LV4


If "Light of Intervention" is active, you cannot Normal Summon "Mystic Swordsman LV4" because it can only be Normal Summoned face-down, which "Light of Intervention" makes impossible to do.

If "Mystic Swordsman LV4" attacks a face-down Defense Position monster, you destroy the monster with "Mystic Swordsman LV4"’s effect before flipping the monster face-up. Effects like "D. D. Warrior Lady" cannot activate.

If a level monster fulfills its condition to Special Summon the next-highest level (for example, if "Armed Dragon LV5" destroys a monster as a result of battle), and the level monster is then flipped face-down, or removed from play permanently, or sent to the Graveyard and then Special Summoned from the Graveyard, then its condition is reset and it is no longer considered to have met the condition to level up to the next level.



MYSTIC SWORDSMAN LV6


The Normal Summon (Tribute Summon) of this monster is the same as a Tribute Set. This card must be in face-down Defense Position when it is Normal Summoned (Tribute Summoned). If you Normal Summon (Tribute Summon) this monster, it is placed face-down on the field; you do not have to show your opponent what monster it is.

If your "Mystic Swordsman LV6" destroys your own monster that is being controlled by your opponent, that monster is sent to the Graveyard. You cannot return it to the top of your opponent’s Deck or the top of your own Deck.

If you activate the effect of "Mystic Swordsman LV6" to place a face-down monster on top of your opponent’s Deck, you do not get to look at it.

If "Mystic Swordsman LV6" attacks a face-down monster, its effect activates at the beginning of the Damage Step, before the monster is flipped face-up. If "Ceasefire" was activated during the Battle Step to flip the monster face-up, then the effect of "Mystic Swordsman LV6" is not activated.

A monster destroyed by the effect of "Mystic Swordsman LV6" is not destroyed as a result of battle. There is no damage calculation. It is not flipped face-up. Any Flip Effects it has are not activated.



MYSTIC TOMATO


If you attack with your "Mystic Tomato" and it is destroyed as a result of battle, you may attack with the monster Special Summoned by "Mystic Tomato" before entering Main Phase 2.

If your opponent controls your "Mystic Tomato" and it is destroyed as a result of battle, you get the effect of "Mystic Tomato" NOT your opponent.

Since the Special Summoning occurs during the Damage Step, "Torrential Tribute", etc. cannot be used.



MYSTICAL KNIGHT OF JACKAL


In order to activate the effect of "Mystical Knight of Jackal", the monster that "Mystical Knight of Jackal" destroyed as a result of battle must be your opponent’s own monster, not one of your monsters that your opponent controls.

"Mystical Knight of Jackal" sends a monster to the Graveyard as a result of battle, and THEN returns it to the top of the deck, so "Sangan" or "Witch of the Black Forest", etc., will activate their effects.

If "Banisher of the Light" is in play, the monster is removed from play and "Mystical Knight of Jackal" does not activate its effect so the monster does not return to the top of the Deck.

If "Mystical Knight of Jackal" attacks a face-down "Man-Eater Bug", and "Man-Eater Bug" destroys "Mystical Knight of Jackal", then the effect of "Mystical Knight of Jackal" is not applied.

"Mystical Knight of Jackal" does activate its effect even if "Necrovalley" is in play.

When "Mystical Knight of Jackal" attacks "Mystic Tomato", during the End Step both effects activate simultaneously once "Mystic Tomato" is sent to the Graveyard, so they form a chain. The turn player’s effect is Step 1 of a chain, and the opponent’s is Step 2; so "Mystic Tomato" resolves first, and a monster is Special Summoned and the Deck shuffled. Then the turn player chooses whether to place "Mystic Tomato" on top of the owner’s Deck with the effect of "Mystical Knight of Jackal".



MYSTIK WOK


Tributing a monster for "Mystik Wok" is a cost, so you can Tribute "The Legendary Fisherman" or "The Agent of Force - Mars".

The ATK or DEF is the current number, not the original number.

You select ATK or DEF when "Mystik Wok" is activated.

You can Tribute face-down monsters, or your opponent's monster using "Soul Exchange".



NARROW PASS


"Narrow Pass" can only be activated when Player A has 2 or fewer monsters and Player B has 2 or fewer monsters. So if there are 3 monsters in play (2 controlled by A and 1 by B) you can activate "Narrow Pass". But if either player controls 3 or more monsters on his side of the field then you cannot activate this card.

Once "Narrow Pass" is activate, as long as it remains face-up on the field, Player A can Normal Summon or Set 2 up to 2 additional monsters, and Player B can Normal Summon or Set up to 2 additional monsters. It is helpful to place counters on "Narrow Pass" to keep track.

If "Narrow Pass" is activate, and a player Normal Summons his 2 permitted monsters afterwards, if 1 of those is destroyed then he cannot replace it with another Normal Summon. Each player gets 2 additional Normal Summons or Sets, no matter what happens to those monsters afterwards.

"Narrow Pass" does not restrict Special Summons or Flip Summons.



NECROVALLEY


"Necrovalley" negates any effect that targets a card or cards in the Graveyard. So "Necrovalley" WILL negate the effect of: "Monster Reborn", "Premature Burial", "Call of the Haunted", "Question", "Backup Soldier", "Spear Cretin", "The Shallow Grave", "Magician of Faith", "Fiber Jar", "Penguin Knight", and "Agido".

"Necrovalley" negates costs and effects that require removing cards from the Graveyard. So "Necrovalley" WILL prevent a player from removing cards in the Graveyard from play to activate the effect of "Bazoo the Soul-Eater" or "Chaosrider Gustaph". "Necrovalley" WILL prevent a player from removing cards in the Graveyard from play to Special Summon "Dark Necrofear" or "Black Luster Soldier – Envoy of the Beginning". "Necrovalley" WILL negate card effects like "Big Burn", "Gravedigger Ghoul", "Disappear", and "Soul Release".

"Necrovalley" will NOT negate effects that are activated when a card is sent TO the Graveyard or that activate IN the Graveyard or that count cards in the Graveyard. So it will NOT negate the effects of "Sangan", "Witch of the Black Forest", "Black Pendant", "Giant Rat", "Mystic Tomato", "Kuriboh", "Graceful Charity", "Sinister Serpent", "Marie the Fallen One", "Buster Blader", "Shadow Ghoul", "Helpoemer", "Sword of Deep-Seated", "Vampire Lord", "Coffin Seller", and "Magical Thorn".

"Necrovalley" will NOT negate effects that do not target a card or cards in the Graveyard. So "Necrovalley" will NOT negate the effects of "Dark Necrofear" (when destroyed and sent to the Graveyard), "Revival Jam", "Winged Sage Falcos", "Twin-Headed Behemoth", "Mystical Knight of Jackal", and "Red-Moon Baby".

If "Necrovalley" is on the field, you can Special Summon "Gilasaurus" using its effect, but the effect that lets your opponent Special Summon is negated.

If the effect of "Necrovalley" is negated by "Imperial Order", then cards that require "Necrovalley" on the field, such as "Gravekeeper’s Assailant", etc., can still apply their effects because "Necrovalley" is still on the field.

If "Necrovalley" is active, neither player may activate "Book of Life".

If "Necrovalley" is active and you Special Summon the Spell Card "Gravekeeper’s Servant" with "Magical Hats", its ATK and DEF will be 500.



NEEDLE BURROWER


The Level of the destroyed monster is the original Level.

You can use "Barrel Behind the Door" against "Needle Burrower"'s effect.



NEEDLE CEILING


If the number of monsters on the field is reduced below 4 after activation of "Needle Ceiling" (by chaining "Ring of Destruction", etc.), the effect of "Needle Ceiling" still resolves (see "Activation & Targeting Eligibility" on the Advanced FAQ).

Face-down monsters and Monster Tokens are included in determining the number of monsters on the field.



NEEDLE WALL


If you have multiple "Needle Walls", roll a die for each.

If you activate this card (flip it face-up) during your Standby Phase, you still roll during that same Standby Phase.



NEEDLE WORM


If there are fewer than 5 cards in your opponent’s Deck when this card’s Flip Effect is activated, all remaining cards in the Deck are placed in the Graveyard. The opponent does not lose immediately, but will lose if unable to draw a card when required (such as during their next Draw Phase).



NEKO MANE KING


When "Neko Mane King" ends your opponent's turn, your opponent proceeds immediately to his/her End Phase, even if "Neko Mane King" is sent to the Graveyard during the Damage Step.

"Neko Mane King" doesn't actually end the turn, it advances play to the End Phase, so "Destiny Board" can still be used, etc.

"Neko Mane King"'s effect activates even if it is sent to the Graveyard while face-down on the field, or sent to the Graveyard from your Deck or hand.

When "Neko Mane King" is sent to the Graveyard by the effect of "Delinquent Duo" or "Card Destruction", "Neko Mane King"'s effect is activated after those cards completely resolve all of their effects.

"Neko Mane King"'s effect only activates when the owner controls it; if the opponent controls "Neko Mane King" then its effect is not activated.

When "Neko Mane King" is designated by "Prohibition", its effect is not activated.



NEWDORIA


You can destroy a face-down monster with "Newdoria".



NIGHT ASSAILANT


"Night Assailant" doesn't have to be sent to the Graveyard by an effect, or by an effect controlled by your opponent; it just has to be sent to the Graveyard. "Night Assailant"'s effect activates when sent to the Graveyard as a cost for "Magic Jammer" or "Tribe-Infecting Virus"; "Night Assailant"'s effect activates after the current chain resolves.

"Night Assailant"'s effect activates when sent to the Graveyard by "Morphing Jar" or "Card Destruction".

"Night Assailant"'s effect activates when sent to the Graveyard for a Ritual Summon.

When "Night Assailant" is sent to the Graveyard by the effect of "Last Turn", FIRST resolve "Last Turn"'s effect of sending all cards on the field and in the hands to the Graveyard, SECOND activate and resolve the effect of "Night Assailant", and THIRD Special Summon a monster by the effect of "Last Turn".

You cannot select the "Night Assailant" that was itself sent to the Graveyard, so there is no infinite loop.

When multiple "Night Assailants" are sent to the Graveyard at the same time because of "Graceful Charity", etc., both can be returned to your hand because "Night Assailant" cannot select itself but CAN select a different "Night Assailant", even one that was sent to the Graveyard at the same time.

Both of "Night Assailant"'s effects target.

You cannot use "Night Assailant"'s second effect while "Necrovalley" is active. 

If your opponent has your "Night Assailant" in his hand (because of "Exchange") and it's sent to the Graveyard, you (the owner) get the effect.

If you have "Forced Requisition" active (face-up) and 7 cards in your hand during the End Phase (and one of them is a "Night Assailant"), and there is another "Night Assailant" in your Graveyard, and you discard your "Night Assailant" because you have 7 cards, your opponent must discard because of "Forced Requisition". Then you can activate the effect of "Night Assailant" to retrieve the other "Night Assailant". Now you have 7 cards in your hand again so you can discard "Night Assailant", and your opponent must discard again for "Forced Requisition". You can continue doing this until your opponent loses all cards in their hand.



NIGHTMARE WHEEL


You can target a face-down monster for "Nightmare Wheel".

If you activate "Nightmare Wheel" during the Battle Step and target a monster that is attacking, the attack stops.

"Nightmare Wheel" targets. You select the monster when "Nightmare Wheel" is activated.

"Nightmare Wheel" is destroyed when the targeted monster is destroyed, returned to the hand, removed from play, send to the Graveyard, etc.

"Nightmare Wheel" is NOT destroyed if the monster is flipped face-down. "Nightmare Wheel" continues to target the monster, inflict damage, and prevent the monster from attacking or changing battle position.

If a face-down monster targeted by the effect of “Nightmare Wheel” is rearranged by the effect of “Wandering Mummy” or “Shifting Shadows”, the monster’s controller must honestly announce which monster is the target of “Nightmare Wheel”.

The effect of "Nightmare Wheel" will be negated by "Royal Decree", so you can attack or change the battle position of the monster. Also, if "Royal Decree" is active, and the monster is removed from the field, "Nightmare Wheel" remains on the field meaninglessly because its text that would destroy it is negated. If "Royal Decree" is later destroyed, the effects of "Nightmare Wheel" are not applied (such as the 500 damage) if there is no monster being targeted by "Nightmare Wheel".

The effect of "Nightmare Wheel" is still applied if the targeted monster changes sides.

If the monster targeted by "Nightmare Wheel" becomes equipped to "Relinquished", then "Nightmare Wheel" is destroyed.



NINJA GRANDMASTER SASUKE


"Ninja Grandmaster Sasuke"’s effect activates at the beginning of the Damage Step, before the monster is flipped face-up. So if "Ninja Grandmaster Sasuke" attacks a face-down Defense Position monster, "Ninja Grandmaster Sasuke" will not destroy it with his effect because it is not flipped face-up until after "Ninja Grandmaster Sasuke"’s effect would activate.

A face-up Defense Position "Spirit Reaper" will be destroyed by the effect of "Ninja Grandmaster Sasuke". "Ninja Grandmaster Sasuke"’s effect does not target. So if "Ninja Grandmaster Sasuke" attacks "Spirit Reaper", "Spirit Reaper" is destroyed by "Ninja Grandmaster Sasuke"’s effect, not by "Spirit Reaper"’s effect.

If "Ninja Grandmaster Sasuke" attacks a face-up Defense Position "D. D. Warrior Lady", "D. D. Warrior Lady" is destroyed by the effect of "Ninja Grandmaster Sasuke" and "D. D. Warrior Lady"’s effect is not activated.

If "Ninja Grandmaster Sasuke" attacks a face-up Defense Position monster, and you flip it face-down during the Battle Step with "Book of Moon", the monster is face-down at the start of the Damage Step so "Ninja Grandmaster Sasuke" will not destroy it with his effect.

If "Ninja Grandmaster Sasuke" attacks a face-down Defense Position monster, and "Ceasefire" is activated during the Battle Step, the monster is face-up at the start of the Damage Step so it will be destroyed by "Ninja Grandmaster Sasuke"’s effect.



NINJITSU ART OF DECOY


If the Ninja is destroyed or otherwise removed from the field by a card effect, "Ninjitsu Art of Decoy" remains on the field meaninglessly.

If the Ninja is removed from the field temporarily, or flipped face-down, "Ninjitsu Art of Decoy"’s effect is no longer applied.

If "Ninjitsu Art of Decoy" is active, then "Royal Decree" is activated and negates "Ninjitsu Art of Decoy"’s effect, then "Royal Decree" is later destroyed, "Ninjitsu Art of Decoy"’s effect is not re-applied.



NINJITSU ART OF TRANSFORMATION


"Ninjitsu Art of Transformation" does not target; you select the monster to Special Summon when you resolve its effect.

If "The Legendary Ocean" is active, your WATER monsters in your hand are lowered by 1 level so if you Special Summon from your hand using "Ninjitsu Art of Transformation", you can Summon at 1 level lower (effectively making it Level +4 if looking at the original Level).

"The selected card" means the Tributed card.



NITRO UNIT


If you equip “Nitro Unit” to a monster on your opponent’s side of the field, then you take control of that monster, “Nitro Unit” is destroyed because the monster is no longer on your opponent’s side of the field.

If your opponent controls your monster, and you target it with “Nitro Unit”, but your opponent chains “Remove Brainwashing”, “Nitro Unit” is destroyed because its target is no longer on your opponent’s side of the field when “Nitro Unit” resolves.

When the monster equipped with “Nitro Unit” is destroyed and sent to the Graveyard as a result of battle, the effect of “Nitro Unit” can be chained to.

The damage inflicted by “Nitro Unit” is based on the equipped monster’s original ATK (in the Graveyard).



NOBLEMAN OF CROSSOUT


If the targeted monster is a Flip Effect Monster, it is not flipped face-up and its Flip Effect is not activated. Both players must reveal their Decks to each other to verify that all cards of the same name as the Flip Effect Monster are removed from play.

The targeted monster, and any cards of the same name if the target was a Flip Effect Monster, are removed from play and never go to the Graveyard, so the effects of cards like "Sangan" will not activate.

Cards of the same name in your hand or on the field are NOT removed from play.



NOBLEMAN-EATER BUG


If you activate the effect of "Nobleman-Eater Bug" and select 2 monsters, then "Ring of Destruction" is chained and destroys 1 of the selected monsters, you still destroy the remaining monster when "Nobleman-Eater Bug"’s effect resolves.

If "Nobleman-Eater Bug" is the only monster on the field and it is flipped face-up, then it destroys itself with its effect.



NON AGGRESSION AREA


If your opponent Flip Summons "Cyber Jar" while "Non-Aggression Area" is active, because he cannot Special Summon, the cards he would normally Summon that were picked up are destroyed. All the cards picked up with "Cyber Jar" that would not normally be Special Summoned (such as high-level monsters, Spell and Trap Cards, and monsters that are Special Summon-only) remain in the hand and are not destroyed.

If you activate "Non-Aggression Area", your opponent can still Special Summon THIS turn with "Call of the Haunted", etc.



NON-SPELLCASTING AREA


While "Non-Spellcasting Area" is active, you cannot use face-up monsters on the field, except Effect Monsters, for "Polymerization" or Ritual Spell Cards.

While "Non-Spellcasting Area" is active, no Spell Card, including "Raigeki" or Equip Spell Cards, can affect a monster, unless it is an Effect Monster.

While "Non-Spellcasting Area" is active, and only one player has Effect Monsters on the field, you can activate “Creature Swap” but its effect will be negated because none of the non-Effect Monsters can switch control due to a Spell Card’s effect.

The effect of “Non-Spellcasting Area” includes Ritual Monsters and Fusion Monsters that do not have effects, as well as Monster Tokens.



NUBIAN GUARD


"Nubian Guard"'s effect is resolved after damage calculation.

"Nubian Guard"'s effect does target a monster in the Graveyard, so the effect will be negated if "The End of Anubis" is face-up on the field.



NULL AND VOID


You can only chain "Null and Void" to an effect that draws cards and does nothing else. You can chain "Null and Void" to the activation of "Pot of Greed" or "Jar of Greed". You can chain "Null and Void" to the activation of the effect of cards like "Airknight Parshath".

You can chain "Null and Void" to a Continuous Spell or Trap Card that causes drawing, such as "Mirage of Nightmare" or "Heart of the Underdog".

You cannot chain "Null and Void" to "Disturbance Strategy", "Graceful Charity", "Card Destruction", "Morphing Jar", "Mind Wipe", "Dragged Down into the Grave", or "Reload".

You can activate "Null and Void" during the Damage Step, for example against the effects of "Airknight Parshath", "Sasuke Samurai #3" or "Bistro Butcher".

The card(s) discarded by the effect of "Null and Void" are never treated as actually drawn, so they are considered sent from the Deck to the Graveyard.

You can chain "Null and Void" to "Reckless Greed". Since you cannot draw by the effect of "Reckless Greed", the effect of skipping 2 Draw Phases is NOT applied.

You can chain "Null and Void" to the effect of "Royal Magical Library".

You cannot chain "Null and Void" to the effect of "Appropriate" because the effect of "Appropriate" cannot be chained to.



NUTRIENT Z


This card can only be activated during your opponent’s Damage Step during the "Calculate and Apply Damage" portion or at any point in the Damage Step prior to that.

You must take the 2000 points or more of Battle Damage from a single attack. If you take 1000 points of damage from one attack, and then 1200 points of damage from a second attack, the effect of this card will not activate. 

If "Hayabusa Knight" attacks you directly twice, the effect of this card will not activate. The Battle Damage must come from a single attack, not a single monster attacking twice.

You can activate 2 copies of "Nutrient Z" and you will gain 8000 Life Points if you would take 2000 points or more of Battle Damage.

You cannot activate "Kuriboh" in a chain to "Nutrient Z"’s effect. The effect of "Kuriboh" would reduce the Battle Damage to 0, and then the effect of "Nutrient Z" will no longer increase you Life Points. You must actually take the damage to gain the benefit of "Nutrient Z"’s effect.



NUVIA THE WICKED


If "Light of Intervention" is on the field this card cannot be Set and if Normal Summoned in face-up Defense Position it will be destroyed.



OBNOXIOUS CELTIC GUARD


"Obnoxious Celtic Guard" and "Celtic Guardian" are considered 2 separate monsters so you can have 3 of each in your Deck.

"Obnoxious Celtic Guard"’s effect looks at the ATK during Damage Calculation. So if he’s WIND and is attacked by "Insect Soldiers of the Sky", their ATK is 2000 during Damage Calculation and "Obnoxious Celtic Guard" is not destroyed. Or if an 1800 monster attacks and you use "Rush Recklessly" to increase the ATK to 2500 during the Damage Step, "Obnoxious Celtic Guardian" is not destroyed.

"Obnoxious Celtic Guard"’s effect looks at current ATK, not original ATK. So a monster with 1000 original ATK equipped with "Megamorph" to make it 2000 ATK will not destroy "Obnoxious Celtic Guard" as a result of battle.

"Obnoxious Celtic Guard" isn’t destroyed by damage calculation but can be destroyed by monster effects like "Ryu Kokki".

If "Obnoxious Celtic Guard" is attacked by "Dark Ruler Ha Des", or another monster that negates a card’s effect after it destroys it, "Obnoxious Celtic Guard" is not destroyed (so its effect is not negated).

"Obnoxious Celtic Guard"’s effect works for a battle caused by "Last Turn", so if it battles a monster with ATK 1900 or higher, neither is destroyed and the Duel is a draw.



OFFERINGS TO THE DOOMED


Skipping your next Draw Phase is not a cost, so if your opponent chains "Magic Jammer" or "Imperial Order" to negate this card, you do NOT skip your next Draw Phase.

If your opponent chains "Book of Moon" to flip the target of this card face-down, the monster is not destroyed and you will skip your next Draw Phase.



OJAMA DELTA HURRICANE!!


If your opponent chains "Ring of Destruction" or "Book of Moon" to "Ojama Delta Hurricane!!", and one of the Ojamas is destroyed or flipped face-down, "Ojama Delta Hurricane!!"'s effect still resolves.



OJAMA KING


You cannot select occupied Monster Card Zones with "Ojama King"’s effect. If your opponent has 5 monsters on the field, then "Ojama King"’s effect is not applied.

"Ojama King"’s effect activates and you select up to 3 Monster Card Zones when "Ojama King" becomes face-up on the field.

If you select up to 3 Monster Card Zones and your "Ojama King" is flipped face-down, the Monster Card Zones are usable again. When "Ojama King" is flipped face-up again, you can select up to 3 Monster Card Zones again.

If you take control of your opponent’s face-up "Ojama King", you cannot select new Monster Card Zones because the zones are selected when "Ojama King" becomes face-up on the field.



OJAMA TRIO


You cannot activate "Ojama Trio" if there are not 3 vacant Monster Zones on your opponent's side of the field.

You cannot activate "Ojama Trio" if "Scapegoat" or "The Last Warrior from Another Planet" is preventing you from Summoning.

If there are Ojama Tokens on your opponent's side of the field, and "Remove Brainwashing" is activated, the Ojama Tokens are switched to your side of the field. If you don't have enough Monster Zones for them, some of the Ojama Tokens are destroyed and the damage is inflicted to the opponent.

When you chain Ojama Trio to your opponent's "Call of the Mummy" effect, the effect of "Call of the Mummy" is negated.

When your opponent activates "Snatch Steal", and you chain "Ojama Trio" to fill up his/her remaining Monster Zones, then there is no room for the stolen monster, and it is destroyed.



OMINOUS FORTUNETELLING


The opponent must reveal the randomly selected card to you after you call a type to confirm if you were right or wrong.

If the opponent’s hand is revealed by the effect of "Mind on Air", etc., turn his/her hand face-down and then randomly select a card.

If you have two copies of "Ominous Fortunetelling" on the field, you select a card and call a type for the first copy, and then select a new card and call a type again for the second copy.



OPTI-CAMOUFLAGE ARMOR


After you have declared a direct attack with your monster equipped with "Opti-Camouflage Armor", and then the "Opti-Camouflage Armor" is destroyed during the attack, you can no longer attack directly and a replay occurs.



ORCA MEGA-FORTRESS OF DARKNESS


You can Tribute a face-down "Torpedo Fish" or "Cannonball Spear Shellfish" to activate "Orca Mega-Fortress of Darkness"' effect.



ORDEAL OF A TRAVELER


You can activate the effect of "Ordeal of a Traveler" each time your opponent attacks.

You must show the card your opponent selects to your opponent.

If your opponent calls it right, the attack resolves normally.

You cannot activate "Ordeal of a Traveler"’s effect if you have no cards in your hand.

When "Ordeal of a Traveler" & "Fairy Box" are both active, "Fairy Box" (mandatory) is step 1 of the chain, and "Ordeal of a Traveler" (optional) is step 2.

When you activate "Ordeal of a Traveler"’s effect as a chain to "Magic Cylinder", since "Ordeal of a Traveler" resolves first, if your opponent guesses incorrectly then the attack does not resolve and the effect of "Magic Cylinder" disappears. If multiple copies of "Ordeal of a Traveler" are active, their effects are cumulative.



ORDER TO SMASH


You Tribute when you resolve "Order to Smash"'s effect.

You select the Spell/Trap Card when you resolve "Order to Smash"'s effect.



OUTSTANDING DOG MARRON


When "Outstanding Dog Marron" is sent to the Graveyard during a chain, its effect is activated after the current chain resolves (just like "Witch of the Black Forest").

When "Mystical Knight of Jackal" attacks "Outstanding Dog Marron" and destroys it, the effects are simultaneous. So "Mystical Knight of Jackal"'s effect is Step 1 of a chain and "Outstanding Dog Marron" is Step 2. "Outstanding Dog Marron" is returned to the Deck and "Mystical Knight of Jackal"'s effect disappears.



PANDEMONIUM


You can't use "Pandemonium" to add a Fusion Monster Archfiend from the Fusion Deck to your hand, like "Fiend Skull Dragon".

If multiple Archfiends are destroyed at the same time by "Raigeki", you can only add 1 Archfiend from your Deck to your hand with "Pandemonium".

When your Archfiends controlled by your opponent are sent to your Graveyard, you can add an Archfiend from your Deck to your hand with "Pandemonium".



PANDEMONIUM WATCHBEAR


When your opponent activates "Huge Revolution" while your "Pandemonium Watchbear" is on your side of the field, your "Pandemonium" will not be destroyed.

When your "Pandemonium" is going to be destroyed by "Mystical Space Typhoon", you can chain "Ceasefire" to flip your "Pandemonium Watchbear" face-up, and "Pandemonium" will not be destroyed.



PATRICIAN OF DARKNESS


For this card’s effect, the chosen attack target must still be legal. You cannot force a monster to attack directly if it normally cannot, or force a monster to attack a monster on its own side of the field.

The effect of "Patrician of Darkness" does not override the effects of "Marauding Captain", "The Legendary Fisherman", "Solar Flare Dragon", etc. You cannot choose an attack target prevented by the effects of these cards. Examples: You cannot choose "The Legendary Fisherman" as an attack target if "Umi" is on the field. You cannot choose another Warrior-Type monster as an attack target when you control "Marauding Captain".

"Inaba White Rabbit" must still attack your Life Points directly since it is not able to attack other monsters. You cannot force it to with this card’s effect.

If a monster has the optional effect of attacking directly, such as "Rainbow Flower", you may choose a monster as an attack, or a direct attack. 

When you control "Patrician of Darkness" and a monster equipped with "Ring of Magnetism" you must chose the equipped monster as the attack target.

Replays may occur as normal when this card is on the field. If, after the replay, "Patrician of Darkness" is still on the field and they choose to restart the attack, you will still choose the attack target with the effect of "Patrician of Darkness".

If you control "Patrician of Darkness" and "Lord of D." you may still choose Dragon-Type monsters on your side of the field as attack targets.



PATROID


The effect of “Patroid” targets a card.

If “Patroid” is flipped face-down or removed from the field, its effect is reset and you can use it again that turn if you can get it face-up on the field again.



PENALTY GAME!


"Penalty Game!" only requires your opponent to have 4 cards in hand when it is activated, not when it resolves. So your opponent can activate "Jar of Greed" to have 5 cards, or chain a Quick-Play Spell Card from his hand and have 3 cards, and "Penalty Game!" will still resolve.

If you choose the first effect, neither player can activate a card that would require the opponent to draw during their next Draw Phase, such as "Jar of Greed" or "Disturbance Strategy".

If the second effect of "Penalty Game!" is chosen, the opponent can still activate the effects of cards that are already face-up on the field, such as "Skull Lair" or "The Dragon’s Bead".



PENGUIN SOLDIER


You may choose to return 0, 1, or 2 monsters to their owners’ hands. 

You may target Monster Tokens, and they will be taken off the field, instead of returning to the hand.

Spirit Monsters can still be returned to their owners’ hands by the effect of "Penguin Soldier" even if "Spiritual Energy Settle Machine" is in play.



PENUMBRAL SOLDIER LADY


"Penumbral Soldier Lady"’s ATK increases during the Damage Step and this effect can be chained to.

"Penbumbral Soldier Lady"’s ATK increases when appropriate, no matter whose turn it is or whether she attacked or was attacked.

The increase to "Penumbral Soldier Lady’s" ATK from her effect only lasts until the end of the Damage Step.



PETEN THE DARK CLOWN


Missing the Timing: “Peten the Dark Clown” is a “when… you can” optional Trigger Effect. This means that “Peten” being sent to the Graveyard has to be the very last thing that happened in order to activate its effect.

If “Peten the Dark Clown” is Tributed for a Tribute Summon, the last thing that happened was that a monster was Summoned, so the effect of “Peten” does not activate.

If “Peten the Dark Clown” is Tributed for “Mystik Wok” or “Cannon Soldier”, the last thing that happened was that those effects resolved, so the effect of “Peten” does not activate.

If “Peten the Dark Clown” is destroyed in a chain and not as Chain Link 1, his effect does not activate. (Example: “Pot of Greed” is activated and “Ring of Destruction” is chained, targeting “Peten”.)

If “Peten the Dark Clown” is destroyed by “Cyber Jar”, the last thing that happened was that monsters were Summoned to the field, so the effect of “Peten” does not activate.

If “Peten the Dark Clown” is discarded as a cost for “Tribe-Infecting Virus” or “Raigeki Break”, the last thing that happened was that those effects resolved, so the effect of “Peten” does not activate.

If “Peten the Dark Clown” is discarded because of “Morphing Jar” or “Card Destruction”, the last thing that happened was that both players drew cards. So the effect of “Peten” does not activate.

If “Peten the Dark Clown” is sent to the Graveyard as a result of battle, or by “Painful Choice”, the last thing that happened WAS that “Peten” was sent to the Graveyard, so his effect will activate.



PHARAOH'S TREASURE


You cannot select the "Pharaoh’s Treasure" you just drew and sent to the Graveyard as the card to place in your hand.

You can select a face-up "Pharaoh’s Treasure" in your deck as 1 of the 5 cards for "Painful Choice", but because "Painful Choice" is not a draw, the effect of "Pharaoh’s Treasure" will not be activated.

If you take "Pharaoh’s Treasure" from your opponent’s hand with "Exchange" and activate it, the card goes in your Deck, not the original owner’s Deck. When you draw your opponent’s "Pharaoh’s Treasure" from your Deck after that, the controller gets the effect of "Pharaoh’s Treasure" and retrieves a card from his Graveyard, but "Pharaoh’s Treasure" goes to the owner’s Graveyard.

If "Convulsion of Nature" is active, place "Pharaoh’s Treasure" face-down so that it is the opposite direction of the rest of the cards.

If a face-up "Pharaoh’s Treasure" is in your deck and "Fiber Jar" is activated, shuffle the Deck with "Pharaoh’s Treasure" in it; if you draw the "Pharaoh’s Treasure" in your new 5-card hand, the effect is activated but because there are no cards in the Graveyard to retrieve, its effect disappears.

If you pick up a face-up "Pharaoh’s Treasure" because of "Cyber Jar", this is not drawing so the effect is not activated; you may Set the "Pharaoh’s Treasure" you picked up and activate it again (placing it back into your Deck, etc.).

You cannot activate "Seven Tools of the Bandit" or "Solemn Judgment" when "Pharaoh’s Treasure" is drawn.

You can select a face-up "Pharaoh’s Treasure" from your Deck for "Different Dimension Capsule"; the "Pharaoh’s Treasure" is removed from play and kept face-down until the time elapses, at which point it is added to your hand, but it was not drawn so its effect does not activate.

You can select a face-up "Pharaoh’s Treasure" from your deck with "Cat of Ill Omen"; if "Necrovalley" is not on the field, the "Pharaoh’s Treasure" is placed face-up on top of your Deck and will activate its effect when drawn.

If you have no vacant Spell and Trap Zone spaces when you draw "Pharaoh’s Treasure", you still get the effect of "Pharaoh’s Treasure" because you don’t have to put it on the field.

After "Pharaoh’s Treasure" is placed face-up in the Deck, "Jinzo" will not negate its effect when drawn.

If "Drop Off" is used when a face-up "Pharaoh’s Treasure" is drawn, "Pharaoh’s Treasure" is discarded and its effect disappears.

If you draw a face-up "Pharaoh’s Treasure" with "Graceful Charity", you miss the timing for the effect of "Pharaoh’s Treasure" and the effect disappears. "Pharaoh’s Treasure" is simply added to your hand. In order to apply the effect of "Pharaoh’s Treasure", the very last action must have been to draw. You CAN apply Pharaoh’s Treasure’s effect if it is drawn while face-up due to "Pot of Greed", "Fiber Jar", etc.

If "Pharaoh's Treasure" is drawn from your Deck (face-up) while "Banisher of the Light" is in play, "Pharaoh's Treasure" is removed from play and its effect does not activate.

You select the card in your Graveyard that you wish to add to your hand when "Pharaoh's Treasure" is drawn and activates it effect, so your opponent can chain AFTER you have announced which card you wish to retrieve.



PHOENIX WING WIND BLAST


You cannot target a face-up non-Continuous, non-Equip Spell or Trap Card. This is because they are already “considered to be destroyed” once they are activated (even though they are not sent to the Graveyard until the chain resolves). If you target a face-down Spell or Trap Card, the opponent can activate it as a chain. If it is not Continuous, it will not be returned to the top of the Deck. It will be placed in the Graveyard after the chain resolves, as normal.

You can activate “Phoenix Wing Wind Blast” and target a face-up “Swords of Revealing Light” because it destroys itself by its own effect, instead of being destroyed when activated, like most Normal Spell Cards.



PHYSICAL DOUBLE


You cannot activate "Physical Double" during the Damage Step.

If you activate "Physical Double" and your opponent chains "Ring of Destruction" to destroy his targeted monster, the effect of "Physical Double" disappears.

You can target a Monster Token with "Physical Double" to create a Mirage Token copy of it.

When the targeted monster's Level, Attribute, etc. are changed after "Physical Double" resolves, the stats of the Mirage Token are not changed. When the targeted monster's Level, Attribute, etc., are changed before "Physical Double" resolves, the changed stats are adopted by the Mirage Token.

If a Field Spell Card was active before resolution of "Physical Double" that applied to the targeted monster, it applies to the original monster and to the Mirage Token. So if a Field Spell Card was increasing ATK by +500, the original would get +500 ATK and the Mirage Token would get an additional +500 ATK, for a +1000 ATK bonus total for the Mirage Token over the printed ATK of the original monster. Likewise, when "A Legendary Ocean" is active, and you activate "Physical Double" targeting a WATER monster, the Mirage Token's Level Stars are 2 fewer than the printed Level Stars of the original targeted monster.



PIKERU'S CIRCLE OF ENCHANTMENT


This effect lasts until the end of the End Phase.



PIKERU'S SECOND SIGHT


This card’s effect lasts until the end of your opponent’s second End Phase after this card was activated. 

The opponent shows you all drawn cards, even if they are drawn by a card effect.



PINCH HOPPER


Missing the Timing: Because the effect of "Pinch Hopper" effect is an optional “when… you can” Trigger Effect, "Pinch Hopper" being sent to the Graveyard has to be the very last thing that happened in order for you to activate its effect. So if you Tribute "Pinch Hopper" for a Tribute Summon, you cannot activate the effect of “Pinch Hopper” because the last thing to happen will be the Summoning of the Tribute monster. Also, if you Tribute “Pinch Hopper” for “Cannon Soldier”, the very last thing that happened will be the 500 points of damage inflicted to your opponent, so the effect of “Pinch Hopper” will not activate.

If you offer "Pinch Hopper" as a Tribute to attack with "Insect Queen", you can resolve "Pinch Hopper"'s effect after attack declaration.

When your opponent controls your "Pinch Hopper" and "Pinch Hopper" is sent to the Graveyard, "Pinch Hopper"'s effect does not activate.



PINEAPPLE BLAST


When "Ring of Destruction" or "Call of the Haunted" is chained to "Pineapple Blast", and the number of monsters on the field is changed, count the number of monsters at resolution of "Pineapple Blast"'s effect, not at activation.

If, when "Pineapple Blast" resolves, you have no monsters, all of your opponent's monsters are destroyed too.

If you Summon a monster and want to activate "Pineapple Blast", and your opponent wants to use "Trap Hole", "Pineapple Blast" is Step 1 of the chain and "Trap Hole" is Step 2.



PIRANHA ARMY


The Battle Damage doubled by "Piranha Army"'s effect is still considered Battle Damage (not effect damage).



PITCH-BLACK POWER STONE


You place the 3 Spell Counters on "Pitch-Black Power Stone" even if "Royal Decree" is active, so if your opponent chains "Royal Decree" to your "Pitch-Black Power Stone", or chains "Call of the Haunted" to Special Summon "Jinzo", you still get 3 Spell Counters on it.

"Pitch-Black Power Stone"'s transfer effect targets.

"Pitch-Black Power Stone" may itself receive additional Spell Counters from effects such as "Apprentice Magician".

You can use a Spell Counter from a card like "Breaker the Magical Warrior" and replace "Breaker the Magical Warrior"'s Spell Counter with "Pitch-Black Power Stone" on the same turn (and use "Breaker the Magical Warrior"'s effect again that same turn, if you wish).

If you have multiple "Pitch-Black Power Stones", each can transfer 1 of its Spell Counters per turn.

If you have 1 Spell Counter left on "Pitch-Black Power Stone", and your opponent activates "Mystical Space Typhoon", and you chain the transferring effect of "Pitch-Black Power Stone" (a Spell Speed 2 effect), first the transfer effect resolves and the Spell Counter is moved, then "Pitch-Black Power Stone" is immediately destroyed before "Mystical Space Typhoon" resolves.



PITCH-BLACK WARWOLF


The effect of this monster makes the opponent of this monster’s current controller unable to activate Trap Cards during the Battle Phase. If you take control of your opponent’s monster with "Change of Heart" during your turn, your opponent cannot activate Trap Cards during your Battle Phase, but you can.

The effect of this monster makes your opponent unable to activate Set Trap Cards. However, your opponent can still activate the effects of face-up Trap Cards such as "Type Zero Magic Crusher", "Ultimate Offering", "Skull Lair", "The Dragon’s Bead", and "Astral Barrier".



POISON DRAW FROG


If “Poison Draw Frog” is destroyed by “Acid Trap Hole”, you can draw 1 card.

When a face-up “Poison Draw Frog” equipped to “Relinquished” is sent to the Graveyard, you can draw 1 card.



POISON FANGS


You cannot activate "Barrel Behind the Door" against the damage caused by "Poison Fangs", since it is a Continuous Spell Card.



POLE POSITION


The second effect of "Pole Position" does not begin a chain. When "Pole Position" is removed from the field, the effect is applied immediately and the monster is destroyed.

If "Pole Position" is active, and your opponent controls "Blue-Eyes White Dragon" and "Skull Servant", and you activate "Smashing Ground", "Blue-Eyes White Dragon" is unaffected by Spell Cards, so the effect of "Smashing Ground" disappears.

If you control "Dark Magician" and your opponent controls "Blue-Eyes White Dragon", and you activate "Flint" targeting "Blue-Eyes White Dragon", and your opponent chains "Pole Position", then "Flint" is equipped meaninglessly to "Blue-Eyes White Dragon". If "Blue-Eyes White Dragon" is destroyed, "Flint" can be equipped to "Dark Magician" meaninglessly if you choose (even if other monsters are on the field).

If "Level Limit - Area B" and "Pole Position" are on the field, the highest ATK monster is unaffected by "Level Limit - Area B". If it attacks, and during damage calculation "Mask of Weakness" is activated to reduce its ATK so that it is no longer the highest ATK monster on the field, the effect of "Level Limit - Area B" is applied. Also, the attack stops. Do not perform damage calculation.

You cannot choose to Summon a monster, Set a monster, or Set or activate a Spell or Trap Card, or card effect, if it would cause an infinite loop. 
If you do this by mistake, just rewind the game to before the Summon/Set/activation occurred. 

EXAMPLE #1 
I have "Pole Position", "Luminous Spark" (+500 to LIGHT), and "Gemini Elf" (1900 ATK / EARTH) face-up on the field. “Gemini Elf” is the monster on the field with the highest ATK, so it is unaffected by Spell Cards. If the opponent Summons "X-Head Cannon" (1800 ATK / LIGHT), “Luminous Spark” will raise the ATK of “X-Head Cannon” to 2300, making it the highest ATK monster on the field, so it’s unaffected by Spell Cards, so it drops to 1800 ATK, then increases to 2300, then drops to 1800, etc. This would create an infinite loop. Therefore, the opponent cannot Summon “X-Head Cannon”. 

EXAMPLE #2 
The opponent has "Blue-Eyes White Dragon" (3000 ATK) and “Pole Position” face-up on the field. I have "Gemini Elf" (1900 ATK), and an "Opticlops" (1800 ATK) equipped with "Axe of Despair"(+1000 ATK; 2800 total) face-up on the field, and a Set "Ring of Destruction". If I activate "Ring of Destruction" to destroy "Blue-Eyes White Dragon", then “Opticlops” will be the highest ATK monster on the field, and cause an infinite loop (it is the highest, it isn’t, it is, it isn’t, etc.). Therefore, I cannot target “Blue-Eyes White Dragon” with “Ring of Destruction”. 

EXAMPLE #3 
The opponent has a face-down "Pole Position". I have "Opticlops" (1800 ATK) and "Gemini Elf" (1900 ATK) face-up on the field. I activate "Axe of Despair" (+1000 ATK) and try to equip my "Opticlops" (1800 ATK). The opponent cannot chain "Pole Position", since that would cause an infinite loop. “Pole Position” is an illegal activation. Put it back face-down. 

EXAMPLE #4 
I have "Pole Position", "Blade Knight" (1600 ATK / LIGHT), and "Luminous Spark" (+500 ATK to LIGHT) face-up on the field and 2 cards in my hand. The opponent has "Giant Orc" (2200 ATK / EARTH) face-up on the field, which is the highest-ATK monster on the field. If I Set 1 of the 2 cards in my hand, “Blade Knight” gains +400 ATK with its effect, becomes the highest-ATK monster, and because of “Luminous Spark” an infinite loop is created. So I am not allowed to Set a card. 

If an infinite loop is caused because of game mechanics and not by a player’s voluntary card play, “Pole Position” will be destroyed. When “Pole Position” is destroyed in this way, no monster on the field is destroyed by the effect of "Pole Position".

EXAMPLE #5 
I have "Pole Position" and "Opticlops" (1800 ATK) face-up on the field. The opponent has a "Muka Muka" equipped with "Axe of Despair" face-up on the field with no cards in his hand. At the start of the opponent's turn, he draws a card, making "Muka Muka"s ATK 1900. An infinite loop is created by something that could not be avoided, so “Pole Position” is destroyed. 

EXAMPLE #6 
The opponent has “Blade Knight” (1600 ATK) equipped with “Butterfly Dagger - Elma” (+300 ATK; 1900 ATK total) and 2 cards in hand, along with “Marauding Captain” (1200 ATK). The turn player has “Robbin’ Goblin”, “Pole Position”, and “Giant Orc” (2200 ATK). The turn player attacks “Marauding Captain” with “Giant Orc”, inflicting 1000 points of damage. The opponent has to discard a card because of “Robbin’ Goblin” and an infinite loop is created because “Blade Knight” now fluctuates between 2300 and 2000 ATK (either above or below “Giant Orc”, making it the strongest monster on the field… or not). Therefore, “Pole Position” is destroyed. 

EXAMPLE #7 
I have "Pole Position", "Banner of Courage", and "Opticlops" face-up on the field. The opponent has "Gemini Elf" face-up on the field. When I enter my Battle Phase, an infinite loop is created as “Opticlops” fluctuates between 1800 and 2000 ATK. So “Pole Position” is destroyed. 

EXAMPLE #8 
I have "Pole Position", "Gemini Elf" (1900 ATK / EARTH) and "Mystic Plasma Zone" (+500 ATK to DARK) face-up on the field, and an "Opticlops" (1800 ATK / DARK) in face-down Defense Position. The opponent attacks my face-down "Opticlops" with "Mokey Mokey". When we flip "Opticlops" face-up in the Damage Step, an infinite loop is created as “Opticlops” fluctuates between 1800 and 2300 ATK (either above or below “Gemini Elf”, making it the strongest monster on the field, or not). Therefore, “Pole Position” is destroyed.



POSSESSED DARK SOUL


If the opponent has more Level 3 or lower monsters on the field than you have empty Monster Card Zones after you Tribute this card (the Zone it occupied is now empty), you choose which ones to gain control of and the rest are destroyed. If you choose to destroy "Griggle" or "Ameba" in this manner, their effects do not activate since they never came to your side of the field.

You cannot gain control of face-down monsters with this card’s effect, so the opponent may chain "Book of Moon" selecting a Level 3 or lower monster and they will keep control of it.

You maintain control of the monsters until they are removed from the field.



POT OF GENEROSITY


You return cards to the Deck when you resolve the effect (it’s not a cost).

You cannot activate “Pot of Generosity” if you have only 1 card in your hand besides “Pot of Generosity”.

If an effect is chained to “Pot of Generosity” so that you only have 1 or 0 cards in your hand, the effect of “Pot of Generosity” disappears. Do not return cards to the Deck and do not shuffle.

You can chain “Serial Spell” to “Pot of Generosity”, but you will have no hand so both effects will disappear.



POWER BOND


The ATK bonus for “Power Bond” lasts as long as the Fusion Monster is face-up on the field. If it is flipped face-down or removed from the field, the ATK increase disappears.

The ATK bonus for “Power Bond” is not a fixed number. It is a bonus equal to the original ATK. So if the original ATK changes, so does the bonus from “Power Bond”. For example, if you equip the Fusion Monster with “Megamorph” to change the original ATK, the bonus ATK for “Power Bond” adjusts so that the bonus is equal to the new original ATK. For example, if you Summon “Cyber End Dragon” and then equip it with “Megamorph” while your Life Points are lower, its original ATK will become 8000, so it gains an additional 8000 ATK from “Power Bond” for 16000 ATK total.

You cannot use “Barrel Behind the Door” against the damage from “Power Bond” because the damage happens much later than the activation of the “Power Bond” card.

Even if the Fusion Monster is removed from the field or flipped face-down, you cannot negate the effect of “Power Bond” and the player will still take damage equal to the original ATK.

The damage you take because of “Power Bond” is equal to the original ATK of the Fusion Monster at the time the monster is Special Summoned. If the Fusion Monster has its original ATK changed, this does not affect the damage inflicted by “Power Bond”.

If you Fusion Summon “UFOroid Fighter” with 3000 ATK, and then later in the turn “Skill Drain” is activated, reducing its ATK to 0, you will still take 3000 points of damage during the End Phase. If you send “UFOroid Fighter” to the Graveyard so that its effect resets and its original ATK becomes zero, you still take damage equal to its original ATK at the time it was Special Summoned by “Power Bond”.

You can prevent the damage from “Power Bond” with “Des Wombat”.

If “Non-Spellcasting Area” is active and “Power Bond” is used to Special Summon a Fusion Monster that has no effect, the Fusion Monster will not gain the ATK bonus from “Power Bond”, but the controller will still take damage for “Power Bond” (because the player is not a non-Effect Monster Card).



PRECIOUS CARDS FROM BEYOND


You can't use your "Precious Cards from Beyond" when your opponent offers 2 monsters as a Tribute, only when you do.

"Precious Cards from Beyond" is only for a Tribute Summon or Set, not for a Ritual Summon or Special Summon like "Lava Golem".

If you Tribute Summon "Blue-Eyes White Dragon" for 1 Tribute using "Cost Down", you can't activate "Precious Cards from Beyond"'s effect.

If you have multiple "Precious Cards from Beyond", you can activate each of their effects when you Tribute Summon or Set with 2 or more Tributes.

If you Tribute Summon or Set with 2 monsters, and 1 of them was your opponent's monster that you used with "Change of Heart" or "Soul Exchange", you can activate "Precious Cards from Beyond".



PREMATURE BURIAL


You cannot activate "Tailor of the Fickle" selecting "Premature Burial" as a target.

You cannot activate "Fairy’s Hand Mirror" to make your opponent chose a different monster when they activate "Premature Burial".

If you activate this card and your opponent chains "Imperial Order" the effect of "Premature Burial" is negated and the Special Summon never occurs, but you still pay 800 Life Points. If "Imperial Order" is activated after "Premature Burial" is already on the field, the equipped monster is NOT destroyed and "Premature Burial" remains on the field meaninglessly. If "Premature Burial" is then destroyed while "Imperial Order" is still active, the monster remains on the field, but if the monster is destroyed, "Premature Burial" is also destroyed, since it is still equipped to that monster.

If the equipped monster is flipped face-down "Premature Burial" is destroyed but the monster is not destroyed.



PREPARE TO STRIKE BACK


The effect of “Prepare to Strike Back” can be chained to.

The damage from “Prepare to Strike Back” is effect damage, not battle damage.

“Prepare to Strike Back” does not target.

If an effect is chained to “Prepare to Strike Back” that flips the monster face-down, the effect of “Prepare to Strike Back” is not applied.



PRICKLE FAIRY


If "Prickle Fairy" is changed to an Insect-Type monster with "DNA Surgery", your opponent cannot attack.



PRIMAL SEED


"Primal Seed" can add cards to your hand that were removed from play face-up ("Dimensionhole") or face-down ("Different Dimension Capsule").

You target the 2 removed cards when you activate "Primal Seed".

If you don't have 2 or more cards removed from play, you cannot activate "Primal Seed".

A Fusion Monster selected with "Primal Seed" returns to the Fusion Deck.

The required card only needs to be face-up on the field. It does not need to be a Monster Card, so if “Black Luster Soldier – Envoy of the Beginning” is equipped to “Relinquished”, you can activate “Primal Seed”.



PROTECTOR OF THE SANCTUARY


Your opponent cannot draw with "Airknight Parshath" while you control "Protector of the Sanctuary". 

Most cards that would cause the opponent to draw outside of the Draw Phase, such as "Card Destruction", cannot be activated, even by the controller of "Protector of the Sanctuary". However, effects that are forcibly activated, like "Morphing Jar", can be activated (but results may vary; see below).

If "Protector of the Sanctuary" is on the field, then Flip Effects like "Morphing Jar" will still activate because they must activate when the monster is flipped (whether it was Flip Summoned, flipped by an attack, or flipped by "Book of Taiyou", etc.). 

If "Morphing Jar"'s effect activates, then both players discard their hands, but if you control "Protector of the Sanctuary", your opponent does not draw a new hand. 

You cannot activate cards if they make your opponent draw, such as "Dragged Down Into the Grave", "Card Destruction", or "Disturbance Strategy". 

"Protector of the Sanctuary" prevents your opponent from drawing with "Mirage of Nightmare". However, your opponent can still activate "Mirage of Nightmare", "Appropriate", etc., even though he cannot use their effects at that time. 

If you control "Protector of the Sanctuary", your opponent cannot activate "Super Rejuvenation", "Jar Robber", "Monster Recovery", or "Reload" outside of the Draw Phase. 

If you control "Protector of the Sanctuary", your opponent CAN activate "Reload", "Jar of Greed", "Reckless Greed", etc., during the Draw Phase (either player's).

If you have "Protector of the Sanctuary", your opponent can activate cards like "Gamble" that are random as to whether he can draw, but he cannot draw even if he wins the coin toss. 

You can chain "Call of the Haunted" to a card effect that would make your opponent draw, and if you Special Summon "Protector of the Sanctuary", your opponent does not draw. 

If you have "Protector of the Sanctuary" and your "Bistro Butcher" inflicts damage to your opponent, your opponent doesn't draw.

You cannot activate "Heavy Slump" while you control a face-up "Protector of the Sanctuary".

If "Call of the Haunted" is chained to "Reckless Greed" to Special Summon "Protector of the Sanctuary", you cannot draw for the effect of "Reckless Greed" because of the "Protector of the Sanctuary", so you do not draw and you do not skip 2 Draw Phases.

If "Call of the Haunted" is chained to "Disturbance Strategy" to Special Summon "Protector of the Sanctuary", your opponent adds his hand to the Deck and shuffles it by the effect of "Disturbance Strategy", but "Protector of the Sanctuary" prevents him from drawing.

If "Call of the Haunted" is chained to "Upstart Goblin" to Special Summon "Protector of the Sanctuary", you cannot draw 1 card and your opponent does not gain 1000 Life Points.

If "Call of the Haunted" is chained to "Reload" to Special Summon "Protector of the Sanctuary", your opponent adds his hand to his Deck and shuffles it, but "Protector of the Sanctuary" prevents him from drawing.

If "Call of the Haunted" is chained to "Graceful Charity" to Special Summon "Protector of the Sanctuary", you cannot draw for the effect of "Graceful Charity" and you do not discard 2 cards.

If "Call of the Haunted" is chained to "Mind Wipe" to Special Summon "Protector of the Sanctuary", your opponent adds his hand to the Deck and shuffles, but cannot draw any cards.



PYRAMID ENERGY


You can activate "Pyramid Energy" during the Damage Step.

The effect of "Pyramid Energy" is not applied to monsters summoned after "Pyramid Energy"’s resolution.



PYRAMID TURTLE


You may Special Summon a high-level monster with "Pyramid Turtle"'s effect (like "Vampire Lord" or "Ryu Kokki"), but not a Special-Summon only monster (like "Spirit of the Pharaoh").



PYRO CLOCK OF DESTINY


You can only use "Pyro Clock of Destiny" to advance the turn count by 1 for "Swords of Revealing Light", "Lightforce Sword", or "Final Countdown".



QUESTION


Remember that you cannot shuffle your Graveyard or change the order of cards in your Graveyard at any time.

If a monster is named with "Question" that could not be Special Summoned, "Question"’s effect disappears and the monster is neither Special Summoned nor removed from play. So the effect of "Question" disappears if the bottom monster is incorrectly named and is "Helpoemer", "Dark Ruler Ha Des", etc.

If you would Special Summon "Tyrant Dragon" from the Graveyard using "Question", you must Tribute 1 Dragon and if you cannot you cannot Special Summon "Tyrant Dragon" and the effect of "Question" disappears.



RAGING FLAME SPRITE


The +1000 ATK lasts as long as "Raging Flame Sprite" remains face-up on the field. "Raging Flame Sprite" can continue to get +1000 ATK each time it successfully attacks directly (becoming ATK 1100, then ATK 2100, etc.).

The effect of "Raging Flame Sprite" is a Continuous Effect that cannot be chained to.

The effect of "Raging Flame Sprite" is resolved after damage calculation and before Flip Effects are resolved (so the timing is the same as "Don Zaloog" and "Airknight Parshath").

If "Raging Flame Sprite" is equipped with "Twin Swords of Flashing Light – Tryce", its ATK will increase by 1000 points after each successful attack ("Raging Flame Sprite" must still deal at least 1 point of damage with each attack for its effect to apply). So the second attack will be with +1000 ATK, and it will gain another +1000 ATK after the completion of the second attack.



RAIGEKI


If there are no monsters on your opponent’s side of the field you may not activate "Raigeki".



RARE METALMORPH


If you chain "Rare Metalmorph" to an effect like "Snatch Steal" that targets a monster, "Snatch Steal" is equipped but its effect is negated while "Rare Metalmorph" is active. 

If a monster targeted by "Rare Metalmorph" is flipped face-down, it is no longer targeted by "Rare Metalmorph" and "Rare Metalmorph" remains on the field meaninglessly.



RAREGOLD ARMOR


"Raregold Armor" & "Metalsilver Armor" only apply their effects when the same player controls the Equip Spell Card and the monster it is equipped to; you can equip these cards to a monster controlled by your opponent but the effect is not active.

If you have 2 monsters equipped with "Raregold Armor", then your opponent cannot attack.

If you have a Warrior-Type monster equipped with "Raregold Armor", and "Marauding Captain", your opponent cannot attack.

You have an Amazoness equipped with "Raregold Armor", and "Amazoness Tiger", your opponent cannot attack.

"Ring of Magnetism" 'trumps' "Raregold Armor", "Amazoness Tiger", and "Marauding Captain". So if you have a monster equipped with "Ring of Magnetism", and a monster equipped with "Raregold Armor", the monster equipped with "Ring of Magnetism" is the target of attacks.

If you control "Patrician of Darkness" and have a monster equipped with "Raregold Armor", you can only re-direct attacks to the monster equipped with "Raregold Armor" as it is the only legal target.



RAY OF HOPE


You can't activate "Ray of Hope" if you don't have 2 LIGHT monsters in your Graveyard.



READY FOR INTERCEPTING


If you activate "Ready for Intercepting" after your opponent’s attack declaration to flip face-down the monster which is being attacked, a replay does not occur. Complete the attack as normal. (This must happen during the Battle Step, not the Damage Step.)

If you activate "Ready for Intercepting" and target the attacking monster, it is flipped into face-down Defense Position and the attack ends. (This must happen during the Battle Step, not the Damage Step.)

While the effect of "Light of Intervention" is active, you cannot activate "Ready for Intercepting".

If you chain "Ready for Intercepting" to "Hammer Shot" to flip a monster face-down, that monster will not be included in determining which monster is destroyed by the effect of "Hammer Shot".



REAPER OF THE CARDS


This card can destroy a Trap Card on either side of the field. So if your opponent has no Trap Cards and no Set Spell or Trap Cards, you must destroy a card on your side of the field. If it is face-down Spell Card you must reveal it to your opponent, and it is not destroyed.



REASONING


Pick up cards until you pick up a monster that can be Normal Summoned.

You can Special Summon a high-level monster like "Dark Magician" with "Reasoning", but not Special Summon-only monsters like "Gate Guardian", Ritual Monsters, etc.

If you pick up a Spirit Monster, then all picked up cards are sent to the Graveyard.

If no monster is picked up, shuffle your Deck and put it back in the Deck Zone; the effect of "Reasoning" disappears.

You cannot activate "Reasoning" if you already activated "Scapegoat" this turn.

If "Banisher of the Light" is Special Summoned with "Reasoning", the other cards picked up for "Reasoning" are sent to the Graveyard. The effect of "Banisher of the Light" is not applied until after "Reasoning" resolves.



RECKLESS GREED


If "Reckless Greed" is activated, causing you to skip your next 2 Draw phases, and you also must skip your Draw Phase due to another effect such as "Offerings to the Doomed", the skipped Phases do not accumulate. So if you activate "Reckless Greed" and "Offerings to the Doomed", you only skip 2 Draw Phases.

Skipping a Draw Phase is an effect, not a cost, so if "Reckless Greed" is negated you do not skip your Draw Phases.



RECYCLE


If you meet the condition enough times, you can activate "Recycle" as many times as you want in the same Standby Phase.

You cannot activate "Recycle" if you have no non-Monster Cards in your Graveyard.



RED-EYES B. CHICK


Ignition Effects on monsters cannot be activated while the Effect Monster is face-down. So this face-down monster cannot be Tributed for its own effect. 

If you take control of your opponent’s "Red-Eyes B. Chick", you can activate its effect. In this case, the "Red-Eyes B. Chick" is sent to your opponent’s Graveyard, but you get to Special Summon "Red-Eyes B. Dragon" from your hand.



RED-EYES BLACK METAL DRAGON


This card cannot be Normal Summoned or Set, and must be Special Summoned from the Deck by the condition written on the card. It CANNOT be Special Summoned from your hand. So once it is in your hand, there is no way to Summon this card.



REFLECT BOUNDER


"Reflect Bounder" inflicts its effect damage, then damage calculation is applied normally, then "Reflect Bounder" is destroyed by its own effect.

When an Attack Position "Reflect Bounder" is attacked, it is destroyed by its own effect even if the ATK of "Reflect Bounder" is lower than the ATK of the attacking monster.

The damage inflicted by "Reflect Bounder"'s effect is not Battle Damage, so it cannot be reduced to 0 with "Waboku".

Effects such as "Metalmorph" and "Injection Fairy Lily" happen after "Reflect Bounder"'s effect, because "Reflect Bounder"'s effect happens before damage calculation.

When your opponent attacks your Attack Position "Reflect Bounder", your opponent can use "Barrel Behind the Door" against "Reflect Bounder"'s effect.

When your opponent's "White Magical Hat" with "Axe of Despair" attacks your "Reflect Bounder", "Reflect Bounder" inflicts its effect damage, damage calculation is performed, and "White Magical Hat"'s effect is activated.

When "Reflect Bounder" is attacked by "Dark Ruler Ha Des", "Reflect Bounder" inflicts its effect damage, damage calculation is applied, "Reflect Bounder" is determined to be destroyed as a result of battle, "Dark Ruler Ha Des" negates "Reflect Bounder"'s effect, and "Reflect Bounder" does not destroy itself with its own effect, however it was still destroyed as a result of battle.

"Reflect Bounder"'s effect does not target.

If "Reflect Bounder" is attacked by "D. D. Warrior Lady", and the effect of "Reflect Bounder" is activated, "Reflect Bounder" inflicts damage, damage calculation is performed, and "Reflect Bounder" destroys itself with its own effect and is sent to the Graveyard, so even if "D. D. Warrior Lady" activates her effect, "Reflect Bounder" is not removed from play because it is already in the Graveyard.



RE-FUSION


You cannot use “Re-Fusion” to Special Summon a Fusion Monster that was Summoned with “Magical Scientist”, or otherwise not properly Fusion Summoned.

You can chain to the first part of this card’s effect. However, the last part (that destroys the monster) does not start a chain.




REGENERATING MUMMY


"Regenerating Mummy"'s effect will activate when sent to the Graveyard by the effect of "Morphing Jar" or "Card Destruction".

"Regenerating Mummy"'s effect will activate during the Damage Step because of "Spirit Reaper" or "Don Zaloog".

"Regenerating Mummy"'s effect will activate when destroyed and sent to the Graveyard because of "Chain Destruction".

You can chain to "Regenerating Mummy"'s effect. 

You cannot use the same "Regenerating Mummy" for both parts of "Delinquent Duo"'s effect.



REINFORCEMENT OF THE ARMY


You must reveal the monster you select with this card’s effect to your opponent before placing it in your hand.

You can activate this card even if you have no Level 4 or lower Warrior-Type monsters remaining in your Deck, but you must let your opponent see your Deck to confirm. Shuffle your Deck afterwards.



REINFORCEMENTS


You choose the monster to receive the ATK increase when you activate this card. This card targets.

If you activate two "Reinforcements" on the same monster, its ATK increases by 1000.



RELEASE RESTRAINT


If you do not have any copies of “Gearfried the Swordmaster” in your hand or Deck, you can still activate this card to Tribute “Gearfried the Iron Knight”, but you will need to show your cards to your opponent to confirm.



RELINQUISHED


"Relinquished"’s effect to equip itself with a monster can only be activated during your Main Phase 1 or 2 since it is a Ignition Effect.

A monster equipped to "Relinquished" occupies a Spell & Trap Zone of the controller of "Relinquished". So if you already have 5 Spell & Trap Cards on the field you cannot activate the effect of "Relinquished". Any Equip Spell Cards equipped to the selected monster are destroyed. "Relinquished" gains the ATK and DEF of the monster equipped to it, but not the effects of an Effect Monster.

The selected monster is treated as a Monster Card when it is sent to the Graveyard, so the effects of "Sangan" or "Witch of the Black Forest" would activate, but the effect of "Mystic Tomato" would not, since it was not destroyed as a result of battle.

You can not voluntarily destroy a monster equipped to "Relinquished" but you can use "Mystical Space Typhoon" or "Emergency Provisions" to eliminate it.

"Relinquished" will only inflict its effect damage to your opponent if "Relinquished" would be destroyed as a result of battle and the equipped Monster Card is destroyed instead. When this occurs you inflict damage to your opponent equal to the Battle Damage that the controller of "Relinquished" received; this is the ONLY time "Relinquished" will deal effect damage. (If "Relinquished", equipped with a 1800 ATK monster, attack a 3000 DEF Defense Position monster, "Relinquished’s" controller takes 1200 damage but "Relinquished" does not inflict effect damage to the opponent.)



RELOAD


If you have your opponent's card in your hand and activate "Reload", your opponent's card is shuffled to his/her Deck.

Your opponent can activate "Appropriate" in response to your drawing with "Reload"'s effect.



REMOVE BRAINWASHING


When "Remove Brainwashing" is activated, monsters like "Lava Golem" & "Parasite Paracide" will return to their owner's side of the field, monsters revived with "Monster Reborn" return to their owner's side of the field, monsters taken with "Exchange" and played normally return to their owner's side of the field, etc.

When "Remove Brainwashing" is already active on the field and a switching effect is activated, or "Remove Brainwashing" is chained to a switching effect and is thus active before the switching effect resolves, control switches due to the effect but then switches back to the original owner because of "Remove Brainwashing". So for "Creature Swap", control is changed but then control goes back to the original owners. This means that if you give control of "Griggle" or "Ameba" to your opponent, their effect IS activated even though "Griggle"/"Ameba" then returns to the original owner's control afterwards.

If "Monster Reborn" is activated and "Remove Brainwashing" is chained (or was already active on the field), the monster goes to the side of the field of the player who activated "Monster Reborn", then switches back to the original owner immediately afterwards.

If "Remove Brainwashing" is activated and a player already has 5 monsters on the field, the returning monsters are destroyed. If multiple monsters are returning to the owner due to "Remove Brainwashing", and he does not have enough room for all of them, the player who controlled the monsters chooses the ones that are destroyed and the ones that return successfully.

When "Snatch Steal" is active, the +1000 Life Points effect is applied even if "Remove Brainwashing" has returned control of the monster to the original owner.

"Remove Brainwashing" has no effect on a Monster Card equipped to "Relinquished" or "Thousand-Eyes Restrict", and the Monster Card remains where it is, because it is an Equip Spell Card.

If "Remove Brainwashing" is destroyed, control does not revert again, so if I activate "Change of Heart" and my opponent chains "Remove Brainwashing", control of the monster comes to me and then reverts to my opponent. Then, later in the turn, if "Remove Brainwashing" is destroyed with "Heavy Storm", control does not revert back to me and remains with the original owner. (The same for "Creature Swap", etc.)

If your opponent takes control of your monster with "Snatch Steal", etc., and you activate "Relinquished"'s effect on your next turn to equip the monster to "Relinquished", and your opponent chains "Remove Brainwashing" to "Relinquished"'s effect, control of the monster returns to you before "Relinquished"'s effect resolves and, since you cannot use "Relinquished"'s effect on monsters on your side of the field, "Relinquished"'s effect disappears.

Control of "Blindly Loyal Goblin" cannot change even because of "Remove Brainwashing", so if "Blindly Loyal Goblin" is Summoned due to "Monster Reborn" or using "Exchange", the original owner will not control "Blindly Loyal Goblin".



RESCUE CAT


If one of the monsters Special Summoned by “Rescue Cat”’s effect is flipped face-down, or removed from play temporarily, the effect of “Rescue Cat” is reset and that monster is not destroyed during the End Phase.

If your opponent controls your “Rescue Cat” and activates its effect, your opponent gets the effect and Special Summons Beast-Type monsters from his/her Deck.

You can activate the effect of “Rescue Cat” even if there is only 1 or zero Level 3 or lower Beast-Type monsters in your Deck. However, in this case you cannot Special Summon any Beast-Type monsters for the effect of “Rescue Cat”, and your opponent gets to check your Deck to confirm.




RESHEF THE DARK BEING


The effect of “Reshef the Dark Being” is an Ignition Effect. Discarding is a cost for activation of this effect.

If the monster that you take control of with “Reshef the Dark Being” is flipped face-down, it still returns to the opponent during the End Phase.



RETURN FROM THE DIFFERENT DIMENSION


If a monster Special Summoned by this card is flipped face-down, then it will not be removed from play during the End Phase.



RETURN OF THE DOOMED


This card is activated during your Main Phase 1 or 2 and creates a state that lasts until the end of your turn. If "Spell Canceller" is Summoned after this card was activated, but during the same turn, the state it created is not negated and 1 monster will return to your hand if destroyed during this turn.

If "Banisher of the Light" is on the field, a monster that is destroyed will be removed from play and cannot return to your hand since it never went to the Graveyard.



REVERSAL QUIZ


Sending all cards in the hand and on the field to the Graveyard is a cost. If there are no cards in your hand or on the field you cannot activate this card. You must have a card either in your hand or on the field to activate this card.



REVERSE TRAP


If a card gives a monster +100 ATK, and "Reverse Trap" is activated, that monster now has -100 ATK instead. This card only affects increases and decreases of a defined value, such as +200 (which becomes -200) or -500 (which becomes +500). It does not change cards which "double", "half", or "reduce to 0" the ATK or DEF of a monster.

You cannot activate this card during the Damage Step. This card affects monsters, Spell Cards, and Trap Cards controlled by both players. 

Additional "Reverse Traps" activated in the same turn will have no effect. So "Reverse Trap" will change "Axe of Despair’"s effect of adding 1000 ATK to subtracting 1000 ATK. If a second "Reverse Trap" is activated, the equipped monster still has -1000 ATK.



REVIVAL JAM


If you activate "Change of Heart" to take control of "Revival Jam", and it is sent to the Graveyard as a result of battle, the owner (not you) gets the option to pay 1000 Life Points to Special Summon "Revival Jam" to their side of the field.

The cost of 1000 Life Points is paid when "Revival Jam" is sent to the Graveyard as a result of battle. If "Revival Jam" is removed from the Graveyard before your next Standby Phase by cards like "Disappear" you do not get your Life Points returned to you.

If you pay 1000 Life Points when your "Revival Jam" is sent to the Graveyard, and then activate "Call of the Haunted" to return it to the field before your next Standby Phase, and it is again destroyed you must pay another 1000 Life Points if you want it to return during your next Standby Phase. Its condition was reset when it was taken out of the Graveyard by the effect of "Call of the Haunted".



RING OF DESTRUCTION


You cannot activate "Ring of Destruction" during the Damage Step.

"Ring of Destruction" inflicts damage based on the current (total) ATK value, NOT the original ATK.

This card targets a monster.

If you chain "Ring of Destruction" to "Magic Cylinder", "Magic Cylinder"’s effect disappears because the monster is no longer there (so "Magic Cylinder" inflicts no damage).

If a player Tributes "Witch of the Black Forest" for "Summoned Skull", you can chain "Ring of Destruction" to the effect of "Witch of the Black Forest", in order to destroy "Summoned Skull". If this reduces the player’s Life Points to zero, then they cannot use "Witch of the Black Forest"’s effect (to retrieve a 5th Exodia piece, for example).



RING OF MAGNETISM


If there is a monster equipped with "Ring of Magnetism" on the opponent’s side of the field, if your monsters are going to attack they must attack the equipped monster. Even Toon Monsters, "Inaba White Rabbit", and monsters like "Jinzo #7" and "Queen’s Double" that can normally Attack Directly must attack the equipped monster.

If you have two or more monsters on your side of the field equipped with your "Ring of Magnetism" cards, you choose which monster will be attacked.



RIRYOKU FIELD


This card cannot be used against "Monster Reborn" or "Premature Burial" since they do not target a monster on the field.

This card cannot be used against "Fissure", "Smashing Ground", or "Dark Hole" because these cards do not target.



RISING ENERGY


You can activate “Rising Energy” during the damage step.

Discarding 1 card is a cost to activate “Rising Energy”.



RIVALRY OF WARLORDS


When "Rivalry of Warlords" is activated, each player must send monsters to the Graveyard so that he controls only 1 Type of monster face-up. You don't select or name a Type when "Rivalry of Warlords" is activated; instead, you make it so you have only 1 Type. If, after this, your monsters are destroyed so you have no monsters on the field, you are free to play any Type again, and that new Type becomes the Type that you must play. (So if you send monsters to the Graveyard so you control only Spellcaster-Typess, and your Spellcaster-Type monsters are destroyed, you may play a Dragon-Type monster, but can then only play Dragon-Type monsters as long as you control 1 or more face-up Dragon-Type monsters. If all your monsters are again destroyed, you can again play whatever Type you want.)

This also means that when "Rivalry of Warlords" is active, each player can control a different face-up Type than his opponent.

You can activate "Rivalry of Warlords" when either or both player(s) does not have any face-up monsters on the field, in which case once a player does have a face-up monster that monster's Type becomes that player's Type for purposes of "Rivalry of Warlords" (as long as the monster remains face-up on that player's side of the field).

When "Rivalry of Warlords" is activated, it has no effect on monsters that are face-down at that time and does not flip those monsters face-up.

While "Rivalry of Warlords" is active, you can still Set monsters face-down if they are a different Type than the Type you control. If your face-down monster of a different Type is attacked, then the monster is destroyed after damage calculation. If the destroyed monster of a different Type was a Flip Effect Monster, its Flip Effect is still activated, and then the destroyed monster is sent to the Graveyard. If your face-down monster of a different Type is flipped by "Swords of Revealing Light", "Book of Taiyou", etc., then it is destroyed as necessary.

As long as "Rivalry of Warlords" is active, you cannot Summon, Flip Summon, or Special Summon an inappropriate Type face-up (including "Jinzo"), but you can Special Summon face-down with "The Shallow Grave", "Morphing Jar #2", etc.

If you have only 1 monster on the field face-up, you may Tribute it for a monster that is a different Type.

If you have 2 monsters on the field face-up of the same Type, you cannot Tribute 1 of them for another monster that is a different Type (even "Jinzo") as you would then have 2 different Types.

If "Cyber Jar" is activated while "Rivalry of Warlords" is active, you can Special Summon different Types of monsters face-down without penalty, or Special Summon 1 Type face-up and all the others face-down. But if you Special Summon different Types of monsters face-up, you have to destroy monsters to make it 1 Type.

When "Rivalry of Warlords" is active, and you change the Type of all of your monsters with "DNA Surgery" or "Parasite Paracide" or "D. Tribe", you now only have 1 Type so you are OK and no monsters are destroyed, and you can also Summon, Flip Summon, and Special Summon additional monsters that do not have that printed Type on the card and they will be considered that Type and are not destroyed.

If you activate "Magical Hats" while "Rivalry of Warlords" is active, the cards Special Summoned with "Magical Hats" are unaffected by "Rivalry of Warlords" because they have no Type.

When "Rivalry of Warlords" is active you can activate "Dragonic Attack", but if you have other face-up monsters that are not Dragon-Types then the targeted monster is destroyed.

If "Rivalry of Warlords" is active and you take control of your opponent's face-up monster with "Change of Heart" or "Snatch Steal", and that monster is a different Type than your other face-up monster(s), your opponent's monster is destroyed.



ROBBIN' GOBLIN


If you have "Robbin’ Goblin" on the field and attack with "Kycoo the Ghost Destroyer" or "The Bistro Butcher" both effects activate simultaneously. Since you control both effects you can choose the order that they go on a Chain, so you can have the opponent draw due to the effect of "The Bistro Butcher" and then discard for the effect of "Robbin’ Goblin".



ROC FROM THE VALLEY OF HAZE


Because this effect is a mandatory Trigger Effect, you cannot "miss the timing" with it. So even if you send "Roc from the Valley of Haze" to the Graveyard as a cost, or in the middle of a chain, it will still return to your hand (after resolving the current series of events).



ROCKET JUMPER


If your opponent has only Defense Position monsters on the field, you can attack directly with "Rocket Jumper", but if your opponent has a Spell or Trap Card, you cannot attack directly with "Rocket Jumper".



ROD OF SILENCE - KAY'EST


When you equip "Rod of Silence - Kay'est" to a monster equipped with other Equip Spell Cards, those cards are destroyed.



ROD OF THE MIND'S EYE


The damage caused by "Rod of the Mind's Eye" is Battle Damage, so it can be reduced to zero with "Waboku" or "Kuriboh".

When you equip "Rod of the Mind's Eye" to "Susa Soldier" or "Shadowknight Archfiend", the Battle Damage is 1000 points.

When "Gravekeeper's Vassal" is equipped with "Rod of the Mind's Eye", the effect is not activated because the damage caused by "Gravekeeper's Vassal" is effect damage.



ROPE OF LIFE


Discarding your hand is a cost and the cost must be at least 1 card. So if you have zero cards in your hand, you cannot activate "Rope of Life".

If your monster is controlled by your opponent and sent to your Graveyard, you can activate "Rope of Life". You cannot activate "Rope of Life" when your opponent’s monster you control is sent to his/her Graveyard.

The increase in ATK is permanent as long as the monster remains face-up on the field.

You can use "Rope of Life" to Special Summon "Jinzo" and "Jinzo"'s ATK will increase by 800 points.



ROULETTE BARREL


You can only use "Roulette Barrel"'s effect once per turn.

You have to roll a die twice, not once. You must roll the die twice in a row, not once in Main Phase 1 and once in Main Phase 2, etc.

You CAN select a die roll result which doesn't match the Level Stars of a face-up monster. But if the die roll you select does match a monster, you MUST destroy a face-up monster with the correct number of Level Stars.

"Roulette Barrel" can destroy itself with its effect.

You cannot destroy a monster with 7 or more stars with "Roulette Barrel"'s effect.



ROYAL COMMAND


This card can be chained to the activation of a Flip Effect from a Flip Summon to negate the Flip Effect. It cannot be activated during the Damage Step, so if a Flip Effect Monster is flipped face-up when attacked you cannot chain "Royal Command" to negate its Flip Effect.

If "Royal Command" is active on the field both players may still Flip Summon monsters, but any Flip Effects are negated.



ROYAL KEEPER


The effect of "Royal Keeper" is not a Flip Effect.

When a face-down "Royal Keeper" is attacked and flipped face-up, its +300 ATK effect is applied AFTER damage calculation.

When your opponent activates "Bottomless Trap Hole" against "Royal Keeper", the +300 ATK effect of "Royal Keeper" resolves after "Bottomless Trap Hole".



ROYAL OPPRESSION


There are basically 2 ways to Special Summon a monster. The first way is with a Spell Card like "Monster Reborn", a Trap Card like "Call of the Haunted", or an Effect Monster like "Magical Scientist". The second way is built in to the monster, and Special Summons it without activating an effect, such as "Black Luster Soldier - Envoy of the Beginning" or "Dark Necrofear". "Royal Oppression" can negate both of these types of Special Summon. In the first case, you chain the activation of "Royal Oppression"’s effect to the activation of the Spell, Trap, or Monster Card’s effect, and negate the effect. In the second case, right before the monster is Special Summoned, you can activate the effect of "Royal Oppression" to negate the Special Summon (the same procedure that you use for "Horn of Heaven" or "Solemn Judgment").

Example 1: If "Marauding Captain" is Normal Summoned, its effect activates. You can chain to this effect by activating the effect of "Royal Oppression". The effect of "Marauding Captain" is negated, no monster is Special Summoned, and the "Marauding Captain" is destroyed. (The monster your opponent intended to Special Summon with the effect of "Marauding Captain" remains in his hand.)

Example 2: If "Cyber Jar" is Flip Summoned and its Flip Effect activates, you can activate the effect of "Royal Oppression" in a chain to the Flip Effect. The effect of "Cyber Jar" is negated, no monsters on the field are destroyed by its effect, no cards are picked up, no monsters are Special Summoned, and "Cyber Jar" is destroyed by the effect of "Royal Oppression".

Example 3: If "Call of the Haunted" is activated, you can activate the effect of "Royal Oppression" in a chain. The effect of "Call of the Haunted" is negated, and a monster is not Special Summoned.

The effects of face-up Trap Cards cannot be activated during the Damage Step, so this card’s effect cannot negate the Special Summoning of a monster by the effect of “Mystic Tomato” or a “Cyber Jar” flipped face-up by an attack. 

You can activate the effect of "Royal Oppression" as a chain to "Monster Gate". No cards will be picked up, and no monster will be Special Summoned (The opponent still must have Tributed a monster as a cost).

You can activate the effect of "Royal Oppression" to negate an effect that Summons 1 monster, or Summons multiple monsters (like "Cyber Jar", "The Shallow Grave", or "Valkyrion the Magna Warrior").

If "Royal Oppression" is face-up on the field, and "Monster Reborn" is activated to Special Summon "Jinzo", you can activate the effect of "Royal Oppression" in a chain to negate the Special Summon because "Jinzo" is not on the field until the chain resolves.

If you have "Royal Oppression" face-up on your side of the field, and your opponent attempts to Special Summon "Dark Necrofear", and you activate the effect of your "Royal Oppression", then "Dark Necrofear" will activate its effect in the Graveyard and return to the field as an Equip Spell Card. But if your opponent had "Royal Oppression" face-up on his side of the field, and you activate the effect of your opponent’s "Royal Oppression" to negate the Special Summon of your opponent’s "Dark Necrofear", then "Dark Necrofear" does not activate its effect in the Graveyard, because it was destroyed by an effect controlled by its owner, not by its owner’s opponent (even though the owner did not activate the effect, he still controls the "Royal Oppression" card).

When "Vampire Lord" is Special Summoned by its effect, you can activate the effect of "Royal Oppression" to negate the Special Summon and destroy "Vampire Lord". If your "Vampire Lord" is destroyed in this way by the effect of a "Royal Oppression" card controlled by your opponent, then "Vampire Lord" was destroyed by a card controlled by your opponent, and is Special Summoned during your next Standby Phase.

When "Insect Queen" destroys your opponent’s monster, an "Insect Monster Token" is Special Summoned during the End Phase, and the effect of "Royal Oppression" can be activated at that time to negate the Special Summon and destroy "Insect Queen".

When "Jam Breeding Machine" activates its effect to Special Summon a "Slime Token" in the Standby Phase, and the effect of "Royal Oppression" can be activated at that time to negate the Special Summon and destroy "Jam Breeding Machine".

If the effect of "Royal Oppression" is activated, and "Mystical Space Typhoon" or "Dust Tornado" is chained to destroy "Royal Oppression", then the effect of "Royal Oppression" disappears because it is a Continuous Trap Card, and the Special Summon will not be negated.

Remember that "Royal Oppression" follows the rules of all Continuous Trap Cards. In order to chain the effect of "Royal Oppression" to a card effect, "Royal Oppression" must have already been face-up on the field. For example, if "Monster Reborn" is activated, you cannot flip "Royal Oppression" face-up and activate the effect of "Royal Oppression" in the same chain.



ROYAL TRIBUTE


Both players must show their hands to the opponent when "Royal Tribute" resolves.

If you activate "Royal Tribute" and your opponent chains "Mystical Space Typhoon" to destroy "Necrovalley", the effect of "Royal Tribute" still resolves.



RYU KOKKI


If "Ryu Kokki" battles with "Dark Magician of Chaos", "Ryu Kokki" is destroyed and removed from play by "Dark Magician of Chaos"' effect, and "Dark Magician of Chaos" is removed from play because it is destroyed by "Ryu Kokki"'s effect and removed by its own effect.



RYU SENSHI


This card’s effect that negates Spell Cards that target it is not optional. 

You can Special Summon this card from the Graveyard with "Monster Reborn" because its effect that negates Spell Cards is not active while it is in the Graveyard (but only if was properly Fusion Summoned originally).

A Spell Card that targets this card may be activated, but it will be negated and destroyed.

The effect of this card will not negate "Creature Swap", "Fissure", "Smashing Ground", "Dark Hole", "Raigeki", or similar cards that do not target.

If you try to equip "Fusion Sword Murasame Blade" to this monster, it will be negated and destroyed.
