Individual Rulings (F-K)

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.

FAIRY BOX


If you have two copies of "Fairy Box" active on the field you may flip a coin twice, but only need to call 1 correctly to reduce the attacking monster’s ATK to 0.

The current ATK is reduced to 0, including all Equip Spell Cards. Trap Cards and Quick-Play Spell Cards cannot further increase the monster’s ATK this battle. A monster effect such as "Injection Fairy Lily" can increase its own ATK after "Fairy Box" is successful.

Paying 500 Life Points is optional, if you choose not to pay "Fairy Box" is destroyed.

The effect of "Fairy Box" does not target, so "Lord of D." will not prevent "Fairy Box" from reducing the ATK of an attacking Dragon-Type monster to 0.



FAIRY GUARDIAN


Spell Cards that are eligible for this card’s effect include: Set Spell Cards, Equip Spell Cards, or Continuous Spell Cards destroyed by your opponent’s card effects and Spell Cards negated and destroyed by an opponent’s "Magic Jammer", "Solemn Judgment", "Horus the Black Flame Dragon LV8", etc. It also includes Spell Cards discarded from your hand by your opponent’s card effect, like "Delinquent Duo" or "Confiscation" and Spell Cards sent from your Deck to Graveyard by your opponent’s "Needle Worm", "Don Zaloog", "Vampire Lord", etc.

If you activate "Painful Choice" and a Spell Card is included in the 4 cards that are sent to the Graveyard, it cannot be targeted with the effect of "Fairy Guardian" since it was YOUR "Painful Choice" that sent the card to the Graveyard, even though your opponent decided which card you kept.



FAIRY METEOR CRUSH


You cannot double the effect of "Fairy Meteor Crush" by equipping two copies to the same monster.

If you equip your "Fairy Meteor Crush" to an opponent’s monster, and it attacks a Defense Position monster on your side of the field with ATK greater than your monster’s DEF, the opponent will take the difference as Battle Damage. This is because "your opponent" is the opponent of the player who controls "Fairy Meteor Crush" not necessarily the opponent of the player who controls the monster.

"Kuriboh" or "Waboku" can be used to prevent the damage caused by "Fairy Meteor Crush" because it is Battle Damage.



FAIRY OF THE SPRING


You can Set the Equip Spell Card the same turn you play "Fairy of the Spring".

When you add an Equip Spell Card to your hand with "Fairy of the Spring", and the same turn it is returned to the Deck with "Fiber Jar", and you draw it, you can activate it that same turn.



FALLING DOWN


If there are no Archfiends on your side of the field, "Falling Down" is destroyed immediately, even in the middle of a chain.

The Archfiend you need for "Falling Down" doesn't have to be a monster. Cards like "Axe of Despair", or an Archfiend monster equipped to your "Relinquished", will prevent "Falling Down" from being destroyed.

You can activate "Falling Down" when there are no Archfiends on your side of the field, but it is destroyed immediately before it is equipped to a monster.

You cannot use "Barrel Behind the Door" against the damage from "Falling Down" because you cannot use "Barrel Behind the Door" against a Continuous or Equip Spell Card.



FATAL ABACUS


For the effect of "Fatal Abacus" to trigger, a Monster Card that is being treated as a monster must be sent from the field to the Graveyard. This means that a Monster Card equipped to "Relinquished" or "Sword Hunter" that is sent to the Graveyard will not trigger this effect. Also, a Spell or Trap Card that is destroyed while being treated as a monster by the effect of "Magical Hats" will not trigger this effect.

Monster Tokens do not trigger this card’s effect because they are not sent to the Graveyard.

Monsters that are removed from play and monsters that are destroyed while "Banisher of the Light" is on the field do not trigger this card’s effect. This is because they never go to the Graveyard.

"Sent from the field to the Graveyard" includes cards that are destroyed, Tributed, or sent straight from the field to the Graveyard.

If multiple "Fatal Abacus" cards are active on the field, a player will take 500 points of damage for each when one of their monsters is sent from the field to the Graveyard. So if 2 are active, a player will take 1000 points of damage and if 4 are on the field (you have 3 active and your opponent has 1 active) a player will take 2000 points of damage.

It is the owner of the Monster Card that takes the damage, so if you control your opponent’s monster through the effect of "Change of Heart" and Tribute it, your opponent takes the 500 points of damage.



FEAR FROM THE DARK


"Fear from the Dark" can be Normal Summoned.

Only the owner of "Fear from the Dark" can use its effect, because it has to be sent from your hand to your Graveyard.

When you discard "Fear from the Dark" with "Painful Choice", "Fear from the Dark"'s effect does not activate because it was your own card effect that caused it.

If "Fear from the Dark" is sent to the Graveyard during a card effect's resolution, or during a chain, activate "Fear from the Dark"'s effect after the current effect or chain has resolved.

If "Fear from the Dark" is sent to the Graveyard by "Last Turn"'s effect, "Fear from the Dark" is Special Summoned to the field before the attack of "Last Turn" happens.



FIBER JAR


When this card’s effect is activated all cards on the field, in hand, and in the Graveyards are returned to their owner’s Deck. Fusion Monster Cards in any of these places are returned to the Fusion Deck. Cards removed from play remain removed from play.

When the effect of "Fiber Jar" is activated, "Fiber Jar" itself is united with the Deck, even if it has been attacked and destroyed as a result of battle.

If the effect of "Fiber Jar" activates during the Battle Phase, it does not end the Battle Phase, although the turn player will have no monsters after the effect resolves.

If your opponent’s "Parasite Paracide" is face-up in your Deck when the effect of "Fiber Jar" is activated, it will remain there. The opponent should cut your Deck with his / her eyes closed after you shuffle to ensure fairness.

If "Twin-Headed Behemoth" is returned to the Deck by the effect of "Fiber Jar" and its effect has already been used once this Duel, that condition is not reset. If you again draw and Summon your "Twin-Headed Behemoth" you may not activate its effect again.



FIEND SKULL DRAGON


You cannot use substitute Fusion Material Monsters such as "Beastking of the Swamps" to Fusion Summon this card. You can use the effects of "Metamorphosis", "Magical Scientist", and "Summoner of Illusions" to Special Summon this card.

If your opponent Flip Summons a monster with a Flip Effect, and chains a card like "Offerings to the Doomed" to destroy "Fiend Skull Dragon", the Flip Effect will not be negated since "Fiend Skull Dragon" is no longer on the field when the Flip Effect resolves, and it will only negate Flip Effect "as long as this card remains face-up on the field".

The opponent may activate a Trap Card that targets "Fiend Skull Dragon", but its effect will be negated and the Trap Card destroyed. 

Cards such as "Torrential Tribute", "Bottomless Trap Hole", "Mirror Force", and "Last Turn" will all apply their effects to "Fiend Skull Dragon" because these cards do not target.

You can activate "Call of the Haunted" to Special Summon "Fiend Skull Dragon". After it resolves, "Call of the Haunted" will be destroyed and "Fiend Skull Dragon" will remain on the field. Remember that "Fiend Skull Dragon" must have been properly Fusion Summoned previously in order to Special Summon it from the Graveyard.

You can chain "Call of the Haunted" to the activation of a Flip Effect to Special Summon "Fiend Skull Dragon", and the Flip Effect will be negated.



FIEND'S HAND MIRROR


Since "Mystical Space Typhoon" cannot destroy itself, when you chain "Fiend's Hand Mirror" to your opponent's "Mystical Space Typhoon", you cannot re-direct the "Mystical Space Typhoon" to target itself. But you can re-direct it to target and destroy "Fiend's Hand Mirror".

When your opponent activates "Mystical Space Typhoon" to destroy his/her "Mirage of Nightmare", you can chain "Fiend's Hand Mirror" and have "Mystical Space Typhoon" destroy "Fiend's Hand Mirror" instead.



FINAL ATTACK ORDERS


While "Final Attack Orders" is active, if you attack a face-down Defense Position monster, the monster is changed to Attack Position, then damage calculation is applied with the monster in Attack Position.

While "Final Attack Orders" is active, you can change monsters like "Guardian Sphinx" to face-down Defense Position, and while they are face-down, "Final Attack Orders" has no effect on them.

While "Final Attack Orders" is active, you can change the Battle Positions of monsters with "Curse of Fiend" or "Little-Winguard", but the Battle Positions are immediately changed back to Attack Position by "Final Attack Orders".

While "Final Attack Orders" is active, effects of "Goblin Attack Force", "Giant Orc", and "Dark Zebra" are resolved, but they are immediately changed back to Attack Position.

While "Final Attack Orders" and "Light of Intervention" are active, you can Special Summon a monster in face-up Defense Position, but it is immediately changed to Attack Position.

The effect of "Final Attack Orders" cannot be chained to.



FINAL COUNTDOWN


You count turns for "Final Countdown" like this: Turn 1 is the turn you activate it, Turn 2 is your opponent's turn, Turn 3 is your turn after you activated "Final Countdown", etc.

"Final Countdown" is immediately sent to the Graveyard when it resolves.

You can activate "Pyro Clock of Destiny" to advance the turn count by 1 for "Final Countdown". "Final Countdown" does not have to be on the field when you use "Pyro Clock of Destiny".

You win when the 20th turn ends, before the Draw Phase of the 21st turn.

When your opponent chains "Imperial Order" to your "Final Countdown", the effect of "Final Countdown" is negated and you cannot start counting turns. But if "Final Countdown" is activated and resolves, and later "Imperial Order" is activated, it will have no effect on "Final Countdown" because "Final Countdown" will be in the Graveyard.

When you activate "Final Countdown", and your opponent activates "Final Countdown" during his next turn, and then uses "Pyro Clock of Destiny" to advance his "Final Countdown" by 1, both "Final Countdowns" win at the same time and the Duel is a DRAW.



FINAL DESTINY


Discarding 5 cards from your hand is a cost. You cannot activate this card if you have less than 5 cards in your hand.



FIRE PRINCESS


If you have 1 "Fire Princess" and 2 "Solemn Wishes" on the field, "Fire Princess"’s effect deals 1000 damage to your opponent when you draw. If you have 1 "Fire Princess" and 2 "Marie the Fallen One" in your Graveyard, "Fire Princess"’s effect deals 1000 damage to your opponent during your Standby Phase.

If you have 2 "Fire Princesses" and 1 "Solemn Wishes" on the field, your opponent takes 1000 damage when you draw a card (and takes 2000 damage if you had 2 "Solemn Wishes" on the field instead of 1).

If "Mysterious Puppeteer" is on the field when you Summon "Fire Princess", "Fire Princess"’s effect will deal 500 damage to your opponent because of "Mysterious Puppeteer"’s effect.

If you have "Soul Absorption" and "Fire Princess" face-up on the field when your opponent removes 3 monsters from his Graveyard to Summon "Dark Necrofear" you will gain 1500 Life Points and "Fire Princess"’s effect will deal 500 Damage to your opponent.

If you have a face-up "Fire Princess" and a Set "Poison of the Old Man" when your opponent activates "Dark Hole" you may chain "Poison of the Old Man" to increase your Life Points and the effect of "Fire Princess" will deal 500 damage to your opponent even though she is then destroyed by "Dark Hole", because the effect of "Fire Princess" is a Continuous Effect.



FIRE SORCERER


If you have fewer than 2 cards in your hand when this card is flipped face-up its Flip Effect is not activated.

Removing 2 cards from your hand 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 your hand.



FIREBIRD


The effect of “Firebird” is a Trigger Effect that activates when 1 or more Winged Beast-Type monster(s) on the controller’s side of the field 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 “Firebird”’s effect, including with “Divine Wrath”.

If 2 or more Winged Beast-Type monsters on the controller’s side of the field are destroyed at the same time, the ATK of “Firebird” only increases by 500 points.

Winged Beast-Type tokens on the controller’s side of the field are included and will increase the ATK of “Firebird” when destroyed.

Monsters on the controller’s side of the field that are changed to Winged Beast-Type by “DNA Surgery” are included and will increase the ATK of “Firebird” when destroyed.

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

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




FISSURE


You can activate "Fissure" even if your opponent only has 1 monster on the field.

If there are two or more monsters with equal ATK on your opponent’s side of the field, you (the player who activated "Fissure") select which monster will be destroyed.



FLINT


The effect of "Flint" that equips it to a new monster is an effect that targets. This effect also can be chained to.



FLYING KAMAKIRI #1


If you attack with your "Flying Kamakiri #1" and it is destroyed as a result of battle, you may attack with the monster Special Summoned by "Flying Kamakiri #1" before entering Main Phase 2.

If your opponent controls your "Flying Kamakiri #1" and it is destroyed as a result of battle, you get the effect of "Flying Kamakiri #1" NOT your opponent.

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



FORCED CEASEFIRE


You can activate the effect of a Continuous Trap Card that is already face-up on the field during the turn that “Forced Ceasefire” is active.

This effect applies to both players.




FORMATION UNION


The monster you equip the Union Monster to must be "appropriate", meaning the monster name written in the text of the Union Monster.

The Union Monster is considered to be equipped 'by its effect' so any bonuses the Union Monster grants are granted if equipped with "Formation Union".

A Union Monster that is "detached" during the Battle Phase using "Formation Union" can attack during that Battle Phase.

If the player who would control the Union Monster already has 5 monsters on the field, you cannot activate "Formation Union" and choose the second effect.



FOX FIRE


In order to activate its effect, "Fox Fire" must be face-up when the attack that destroyed it was declared (like "Atomic Firefly"). If a face-down "Fox Fire" is attacked, its effect is not applied even though it is face-up when destroyed.

While "Skill Drain" is active, you can Tribute "Fox Fire" for a Tribute Summon.

If the opponent controls your face-up "Fox Fire", and it is destroyed as a result of battle, it will be Special Summoned to your (the owner’s) side of the field during the End Phase.



FREED THE BRAVE WANDERER


You can only activate "Freed the Brave Wanderer"'s effect during your Main Phase 1 or 2.

"Freed the Brave Wanderer"'s effect targets 1 monster.

If your opponent chains "Rush Recklessly" to "Freed the Brave Wanderer"'s effect to increase "Freed the Brave Wanderer"'s ATK by 700 points, and the ATK of the target monster is now lower than "Freed the Brave Wanderer"'s ATK when its effect resolves, the target monster is not destroyed.

If your opponent chains "Ring of Destruction" to "Freed the Brave Wanderer"'s effect and destroys it, "Freed the Brave Wanderer"'s effect still resolves.

If you activate and resolve "Freed the Brave Wanderer"'s effect, then remove him from play and return him from play, or flip him face-down then face-up again, you can use his effect again that turn.



FREED THE MATCHLESS GENERAL


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.

You can activate "Premature Burial" to Special Summon this card from the Graveyard, and then this card’s effect will negate and destroy "Premature Burial". "Freed the Matchless General" will not be destroyed since the effect of "Premature Burial" was negated by his effect.

If this card is targeted by the effect of a Spell Card while face-down, the Spell Card’s effect resolves.

If your opponent activates "Change of Heart" and gains control of this card while it is face-down, and it is then flipped face-up, they retain control of it until the end of the turn. This is because the effect of "Freed the Matchless General" must be applied when the Spell Card is activated.

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 Spell Cards that do not target.

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

The effect of this card that allows you to forfeit your draw to place a Warrior-Type monster from your Deck into your hand is optional. You do not have to activate it if you don’t want to. If you attempt to activate this effect and find that you do not have any Warrior-Type monsters in your Deck, you do not get your normal draw back. You have already forfeited it.

You can only forfeit your normal draw. If you activate "Jar of Greed" during the Draw Phase, you cannot replace that draw with the effect of "Freed the Matchless General".

If you have two copies of this card on the field, you can still only add 1 Warrior-Type monster to your hand by forfeiting your normal draw.

The activation of this card’s effect that adds a Warrior-Type monster to your hand can be chained to.



FREEZING BEAST


You may use the effect of "Freezing Beast" to destroy a Spell or Trap Card on your side of the field.



FRONTLINE BASE


If you have multiple "Frontline Bases", you can Special Summon 1 Union Monster for each.



FROZEN SOUL


While "Frozen Soul" is in effect, you cannot activate "Last Turn" in the same turn because "Last Turn" includes conducting a Battle Phase.

When you activate "Frozen Soul", and effects are chained that result in the Life Point difference being less than 2000, "Frozen Soul"'s effect still resolves.

When you activate "Frozen Soul", and your opponent skips his next Battle Phase somehow, his Battle Phase of the next turn is skipped with "Frozen Soul".



FULFILLMENT OF THE CONTRACT


You cannot use “Fulfillment of the Contract” to Special Summon a Ritual Monster that was discarded from the hand, or otherwise not properly 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.




FUSHIOH RICHIE


"Fushioh Richie" cannot negate cards like "Bottomless Trap Hole", or "Kisetai", because they do not target.

When your opponent uses "Double Snare" on "Fushioh Richie", "Double Snare" is negated and destroyed.

You can use "Premature Burial" or "Call of the Haunted" to Special Summon "Fushioh Richie" from your Graveyard, as long as "Fushioh Richie" was Special Summoned using the proper method ("Great Dezard") previously.

When "Fushioh Richie" is flipped face-up, you can Special Summon a high-level Zombie from your Graveyard (like "Vampire Lord" or "Ryu Kokki").

"Fusioh Richie"’s effect is activated if attacked and flipped face-up by the attack, or if Flip Summoned, or if flipped face-up by a card effect.



FUSILIER DRAGON, THE DUAL-MODE BEAST


If you Set "Fusilier Dragon, the Dual-Mode Beast", even without Tribute, you do not have to show it to your opponent.

If you Set "Fusilier Dragon, the Dual-Mode Beast" without Tribute, it has ATK 1400 and DEF 1000 when flipped face-up.

If "Fusilier Dragon, the Dual-Mode Beast", with halved ATK and DEF because of its effect, is flipped face-down, and then flipped face-up again, it will then have its full ATK 2800 and DEF 2000.

If you have “Fusilier Dragon, the Dual-Mode Beast” with original ATK of 1400 because you Summoned or Set it without Tribute, and you equip it with “Megamorph”, its original ATK will be 2800 when your Life Points are lower, and 700 when your Life Points are higher.

If you Summoned this card without Tribute, and then "Skill Drain" is later activated, the ATK and DEF are no longer halved. If "Skill Drain" is later destroyed, the ATK and DEF still remain 2800/2000.



FUSION GATE


Fusion Monsters Special Summoned without "Polymerization" while "Fusion Gate" is on the field are still considered properly Summoned by a Fusion Summon. So they may be the target of "Monster Reborn", "Call of the Haunted", etc. (This does not apply to Fusion Monsters Special Summoned by the effects of other cards, such as "Magicial Scientist" or "Summoner of Illusions".)



FUSION RECOVERY


You can use “Fusion Recovery” to retrieve a Fusion Material Monster that was used with “Power Bond” or “Fusion Gate” or “Polymerization”.

You can use “Fusion Recovery” to retrieve a fusion substitute monster like “King of the Swamp” or “Goddess with the Third Eye” as long as it was used in a Fusion Summon. 

“Fusion Recovery” targets 1 monster and 1 “Polymerization” in the Graveyard (so it will be negated by “Necrovalley” or “The End of Anubis”).

If 1 of the targeted cards is no longer in the Graveyard when this effect resolve, you still resolve the rest of the effect as best you can.



FUSION SWORD MURASAME BLADE


If this card is face-down on the field, it can be destroyed by effects that destroy Spell Cards.

When you activate this card, the opponent can chain a card like "Magic Jammer" that will negate its activation and destroy it. 

If you equip this card to "Freed the Matchless General", "Ryu Senshi" or to a Warrior-Type monster you control when you have "Frontier Wiseman" on the field, it is negated and destroyed.

If you equip this card to "Gearfried the Iron Knight" it is not destroyed.

This card is not destroyed by cards that target, like "Mystical Space Typhoon" or "Dust Tornado", or by cards that do not target, like "Heavy Storm", "Harpie’s Feather Duster", or "Gryphon Wing".

If a monster equipped with this card is flipped face-down, or removed from the field, this card is destroyed.

This card can be sent from your hand or your Deck to the Graveyard by the effect of "Confiscation", "Delinquent Duo", etc.

If "Imperial Order" is active, this card can be destroyed by "Dust Tornado", etc.

This card can be returned to the owner’s hand by the effect of "Giant Trunade" or ‘Tornado Bird".

If the monster this card is equipped to has its Type changed to anything but Warrior-Type, this card is destroyed.

If the opponent chains "Mystical Space Typhoon" to the activation of this card, this card is destroyed before its effect can be applied.



GAIA SOUL THE COMBUSTIBLE COLLECTIVE


"Gaia Soul the Combustible Collective" is destroyed during the End Phase even if you don’t activate its effect.

You can only use the effect of "Gaia Soul the Combustible Collective" to Tribute Pyro-Type Monsters once per turn.



GATLING DRAGON


You must destroy as many monsters as possible based on the number of Heads you flip. If you flip 2 Heads, and the only monsters on the field are 1 of your opponent’s monsters and your “Gatling Dragon”, you must destroy both monsters. If there are only 2 monsters on the field and you flip 3 Heads, destroy both monsters.

You cannot activate “My Body as a Shield” as a chain to “Gatling Dragon” because it has not yet been decided if any monster(s) will be destroyed or not.




GEAR GOLEM THE MOVING FORTRESS


You cannot activate this card's effect during your opponent's turn or during Main Phase 2.

You can only activate this card's effect once per turn.

If you activate & resolve this card's effect and then "Skill Drain" is activated, you can still attack directly because "Gear Golem the Moving Fortress"'s effect is already applied and it's still applied even if "Skill Drain" is activated.



GEARFRIED THE SWORDMASTER


If you Tribute 1 “Gearfried the Iron Knight” to activate “Release Restraint”, then chain “Serial Spell”, you can Special Summon 2 “Gearfried the Swordmaster” cards from your Deck.

The Equip Card must be successfully equipped to “Gearfried the Swordmaster” to activate his effect. For example, if “Mystical Space Typhoon” is chained to the activation of an Equip Card, it is destroyed and sent to the Graveyard before resolving, so the effect of “Gearfried the Swordmaster” does not activate.

If your opponent equips “Snatch Steal” to your “Gearfried the Swordmaster”, the effect of “Snatch Steal” resolves first and control changes. Then the effect of “Gearfried the Swordmaster” activates and your opponent gets to select which monster is destroyed.

The effect of “Gearfried the Swordmaster” activates when 1 or more Equip Card(s) are equipped to him. So even if “Collected Power” equips several Equip Cards to him simultaneously, you can only destroy 1 monster with his effect.

The effect of “Gearfried the Swordmaster” is a Trigger Effect that can be chained to, starting a new chain after the current chain resolves. You can chain “Divine Wrath” to the activation of this effect.

The effect of “Gearfried the Swordmaster” can activate even in the Damage Step. For example, if “Brain Jacker” is attacked by “Gearfried the Swordmaster”, and “Waboku” was activated earlier in the turn, “Brain Jacker” will equip to “Gearfried the Swordmaster” and the effect will activate. In this case, the effect of “Gearfried the Swordmaster” will activate after the effect of “Brain Jacker” resolves, and the controller of “Brain Jacker” will select which monster to destroy.

This is a targeting effect that targets 1 monster.

The effect of “Gearfried the Swordmaster” will activate even if a Trap Card is equipped to him (such as “Metalmorph” or “Blast with Chain”).




GETSU FUHMA


If "Getsu Fuhma" is destroyed by damage calculation, its effect still activates as long as it battled a monster and damage calculation was performed.

If an attack is negated by "Magic Cylinder", etc., then "Getsu Fuhma"'s effect does not activate.

If "Getsu Fuhma"'s ATK is large enough to destroy "Vampire Lord" by damage calculation, then "Getsu Fuhma"'s effect doesn't activate and "Vampire Lord" won't be Special Summoned, because it was destroyed by damage calculation and not by a card effect.

If "Getsu Fuhma" is destroyed by "Dark Ruler Ha Des", "Getsu Fuhma"'s effect is not activated.



GHOST KNIGHT OF JACKAL


"Ghost Knight of Jackal"'s effect activates when you send a monster to the Graveyard.

If your "Ghost Knight of Jackal" attacks a face-down "Jowls of Dark Demise", your opponent takes control of "Ghost Knight of Jackal" at the time that "Jowls of Dark Demise" is sent to the Graveyard, and "Ghost Knight of Jackal"'s effect disappears.

If "Ghost Knight of Jackal" is removed from the field or flipped face-down before the monster it destroyed is sent to the Graveyard, then "Ghost Knight of Jackal"'s effect is not applied.

If "Final Attack Orders" is active, you can Special Summon a monster destroyed by "Ghost Knight of Jackal" in Defense Position, but it is changed to Attack Position immediately.

If your "Ghost Knight of Jackal" destroys a monster you own that is on your opponent's side of the field, the effect of "Ghost Knight of Jackal" is not applied because it only applies to "an opponent's monster" that is destroyed.

If "Ghost Knight of Jackal" attacks "Ghost Knight of Jackal", neither effect is applied.



GIANT AXE MUMMY


When a monster with ATK less than "Giant Axe Mummy"’s DEF attacks "Giant Axe Mummy", the monster is treated as being destroyed by the effect of "Giant Axe Mummy", NOT "as a result of battle".



GIANT KOZAKY


The first part of “Giant Kozaky” is a Continuous Effect that does not start a chain. The second part is a Trigger Effect that can be chained to.

You can chain “Barrel Behind the Door” to the Trigger Effect (the damage) of “Giant Kozaky”.

If “Giant Kozaky” is destroyed while face-down, then its effect that inflicts damage is not activated. If “Giant Kozaky” is face-up on the field and is targeted by “Tribute to the Doomed”, and you chain “Book of Moon” so that “Giant Kozaky” is face-down when destroyed by “Tribute to the Doomed”, there is no damage.

Like “Atomic Firefly”, “Foxfire”, and “Poison Draw Frog”, if a face-down “Giant Kozaky” is attacked and destroyed, its effect is not applied. However, if a face-down “Giant Kozaky” is attacked, and is not destroyed by the attack, if “Kozaky” is not face-up on the field, then “Giant Kozaky” is destroyed by its own effect after damage calculation, and damage is inflicted by its effect. 

If “Drillroid” attacks a face-down “Giant Kozaky” while “Kozaky” is not on the field, “Giant Kozaky” is destroyed by the effect of “Drillroid” after being flipped face-up. The effect of “Giant Kozaky” is not applied and it does not inflict damage.

The effect of “Giant Kozaky” that inflicts damage to the controller activates in the Graveyard or the “removed zone”, wherever “Giant Kozaky” goes to after being destroyed. “The End of Anubis” will negate the effect of “Giant Kozaky” if it was destroyed and sent to the Graveyard, but “Banisher of the Light” will not (because “Giant Kozaky” does not have to be “destroyed and sent to the Graveyard”). Nor will “Skill Drain” negate the damage if “Giant Kozaky” is destroyed.

If “Giant Kozaky” is face-up on the field with “Kozaky”, and “Kozaky” is equipped to “Relinquished”, “Giant Kozaky” is not destroyed because a card called “Kozaky” is on the field.

If “Giant Kozaky” is equipped to “Relinquished” as an Equip Spell Card, “Giant Kozaky” will not be destroyed by its effect because it’s not a monster (even if “Kozaky” is not on the field).

If “Giant Kozaky” is equipped to “Relinquished” and is destroyed by “Mystical Space Typhoon” or the effect of “Relinquished”, the effect of “Giant Kozaky” will inflict damage to the controller.



GIANT RAT


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

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

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



GIFT OF THE MARTYR


“Gift of the Martyr” increases the monster’s ATK by the original ATK of the monster sent to the Graveyard.

Sending a monster to the Graveyard is a cost for “Gift of the Martyr”. This is an effect that targets.

You can send a face-down monster to the Graveyard as the cost of “Gift of the Martyr”. Refer to the original ATK of the monster.



GILASAURUS


The effect of this card only activates when you elect to change its Normal Summon to a Special Summon. Not if it is Special Summoned by "Monster Reborn", "Marauding Captain", etc.

You can use the effect of this card to change its Normal Summon to a Special Summon even if your opponent has no monsters in their Graveyard.



GOBLIN KING


If you have 2 "Goblin Kings", or a "Goblin King" equipped with "Raregold Armor" and another Fiend-Type monster, your opponent cannot attack.

"Goblin King"'s second effect includes Fiend-Type monsters on your opponent's side of the field.

Face-down Fiend-Type monsters are not included for "Goblin King"'s second effect.

If you equip "Megamorph" to "Goblin King", "Goblin King"'s ATK is 0.

If you have a Fiend-Type monster and a face-down "Goblin King", and "Goblin King" is attacked, "Goblin King"'s ATK and DEF increase after he's flipped face-up, but before damage calculation is applied.



GOBLIN OF GREED


"Goblin of Greed" prevents discarding as a cost, but not as part of an effect. So "Goblin of Greed" will stop "Kuriboh", but not "Mirage of Nightmare" or "Graceful Charity".

If your opponent activates an effect and discards as a cost, and you chain "Call of the Haunted" to Special Summon "Goblin of Greed", he doesn't stop the effect because the cost was already paid.



GOBLIN THIEF


You can chain "Barrel Behind the Door" to "Goblin Thief".



GOOD GOBLIN HOUSEKEEPING


The number of “Good Goblin Housekeeping” cards referred to by the effect is counted at resolution of this effect. So, if you have no copies of “Good Goblin Housekeeping” in your Graveyard, and you activate “Good Goblin Housekeeping” and chain “Emergency Provisions” to send it to the Graveyard, you would draw 2 cards.

You can activate this card when you have no copies of “Good Goblin Housekeeping” in your Graveyard. You will draw 1 card in this case, then return 1 card from your hand to the bottom of your Deck.




GORA TURTLE


If a face-down "Gora Turtle" is attacked by a monster with ATK higher than 1899, the attack continues and damage calculation is applied normally.

If "Gora Turtle" is face-up on your side of the field, and your opponent’s monster’s ATK is increased over 1899 after the declaration of the attack, the attack continues and damage calculation is applied normally.

If the ATK of "Gora Turtle" is higher than 1899, it cannot attack either.



GORA TURTLE OF ILLUSION


When your opponent equips "Gora Turtle of Illusion" with an Equip Spell Card, the effect of the Equip Spell Card is negated but the card is not destroyed and remains equipped to "Gora Turtle of Illusion".

If "Gora Turtle of Illusion" is equipped with "Snatch Steal", both effects of "Snatch Steal" are negated. But if "Skill Drain" is activated, then "Gora Turtle of Illusion"'s effect is negated, and "Snatch Steal"'s effects will resolve properly.

When your opponent activates a Spell Card that targets a face-down "Gora Turtle of Illusion" as a target, and "Ceasefire" is activated as a chain, "Gora Turtle of Illusion" is flipped face-up and the Spell Card's effect is negated.



GORGON'S EYE


"Gorgon’s Eye" cannot negate the effect of "Sangan", "Witch of the Black Forest", or "Sinister Serpent" because they activate in the Graveyard. If a Defense Position "Slate Warrior" is attacked and destroyed, the effect of "Slate Warrior" that lowers ATK and DEF is applied because it activates in the Graveyard.

"Gorgon’s Eye"’s effect will include monsters in Defense Position that are Summoned after "Gorgon’s Eye" resolves.

If a monster in Defense Position is changed to Attack Position, "Gorgon’s Eye" no longer affects the monster and the monster’s effect will be applied.

If "Gorgon’s Eye" is active and you activate a monster effect, and "Book of Moon" is chained to flip the monster into Defense Position, the monster’s effect is still applied and is not negated by Gorgon’s Eye because it was activated properly.

A Defense Position Flip Effect Monster that is attacked will have its Flip Effect negated by "Gorgon’s Eye" because it remains in Defense Position. A Defense Position Flip Effect Monster that is Flip Summoned will not have its Flip Effect negated because it is now in Attack Position.

If a Defense Position monster has Spell Counters, like "Skilled White Magician" or "Royal Magical Library", the Spell Counters are removed if "Gorgon’s Eye" is activated.

Monsters like "D.D. Warrior Lady" attacked while in Defense Position have their effects negated (because they are used before the monster is sent to the Graveyard).

While "Gorgon’s Eye" is active, if "Relinquished" equipped with a monster is in Defense Position, the effect of "Relinquished" is negated, it can no longer be equipped with a monster, and the Monster Card equipped to "Relinquished" is destroyed and sent to the Graveyard.



GRACEFUL CHARITY


Your opponent cannot activate "Appropriate" after you activate "Graceful Charity" since the last effect that resolves with "Graceful Charity" is discarding, not drawing, and your opponent misses the timing. But if your opponent already has an active "Appropriate" face-up on the field, he/she can draw 2 cards after you activate "Graceful Charity".

If "Solemn Wishes" is on the field when you activate "Graceful Charity", you gain 500 Life Points after you finish both drawing and discarding. If "Solemn Wishes" and "Skull Invitation" are on the field, you finish both drawing and discarding for the effect of "Graceful Charity" then you gain 500 Life Points, then you lose 600 Life Points.

If you have three pieces of Exodia in your hand, "Graceful Charity", and no other cards, and then you activate "Graceful Charity" and draw the final 2 pieces of Exodia, you must discard 2 cards before a victory can be declared, but after you discard you will no longer have all 5 pieces of Exodia, and cannot declare a victory.




GRADIUS' OPTION


The ATK/DEF of "Gradius’ Option" is the same as the current ATK/DEF of the selected "Gradius", not the original ATK/DEF. So if you equip "Axe of Despair" to "Gradius", the ATK of "Gradius’ Option" will also increase by 1000 points.

Equipping "Axe of Despair" to "Gradius’ Option" has no purpose. Activating "Reinforcements" targeting "Gradius’ Option" serves no purpose. "Luminous Spark" on the field will not change the ATK/DEF of "Gradius’ Option". It always has the same ATK/DEF of the selected "Gradius".

If the selected "Gradius" is flipped face-down, "Gradius’ Option" is destroyed.

If the selected "Gradius" is temporarily removed from play by the effect of "Interdimensional Matter Transporter" or "Dimensionhole", "Gradius’ Option" is destroyed.

If "Gradius’ Option" is temporarily removed from play by the effect of "Interdimensional Matter Transporter" or "Dimensionhole", when it returns to the field you must select a new "Gradius". If there is no "Gradius" on the field, it is destroyed.

If you pick up "Gradius’ Option" by the effect of "Cyber Jar" you cannot Special Summon it, even if "Gradius" is also in the 5 cards you picked up. It is placed in your hand instead.

If you pick up "Gradius’ Option" by the effect of "Morphing Jar #2" you cannot Special Summon it, and it is sent to the Graveyard.



GRANADORA


For the first effect (gaining Life Points), it is the controller of "Granadora" who gains. For the second effect (losing Life Points), it is the owner of "Granadora" who takes damage.

When your face-down "Granadora" is destroyed, you take 2000 damage.

When your "Granadora" is destroyed and sent to the Graveyard, you can activate "Barrel Behind the Door" against the damage.

When "Granadora" is destroyed and sent to the Graveyard from the field, your hand, or from your Deck, its effect is activated.

When "Granadora"'s Summon is negated and it is destroyed, by "Solemn Judgment" or "Horn of Heaven", the owner of "Granadora" takes the damage.



GRANMARG THE ROCK MONARCH


As with most targeting effects that have specific conditions, if the targeted card is flipped face-up in a chain (for example, if it is a monster and “Ceasefire” is activated, or if it is a Trap Card and is chained to the effect of “Granmarg the Rock Monarch”), then the effect of “Granmarg the Rock Monarch” disappears.

The effect of “Granmarg the Rock Monarch” is an effect that targets. You select the targets when you activate the effect.




GRAVE LURE


If your Deck is already face-up because of “Convulsion of Nature”, then the card from “Grave Lure” is turned face-down.



GRAVE OHJA


If you control “Grave Ohja” and you Flip Summon a Flip Effect Monster, the two effects go on a chain. You can choose which effect is chain link 1.

If you control multiple copies of “Grave Ohja” and Flip Summon a monster, the effects go on a chain and you can choose the order of the chain links.

The second effect of “Grave Ohja” is a Trigger Effect that activates when a monster is Flip Summoned. It can be chained to.

If “Grave Ohja” is attacked, and you activate “Book of Moon” to flip another monster on your side of the field face-down, “Grave Ohja” has already been selected as the attack target so the attack proceeds as normal.



GRAVE PROTECTOR


"Grave Protector"'s effect is not applied to itself when it is destroyed as a result of battle. 

Effects like "Mystic Tomato", etc., are not activated while "Grave Protector" is face-up on the field. 

A monster destroyed by "Dark Magician of Chaos" or "Lesser Fiend" is returned to the Deck instead of being removed from play. 

A monster that battles with "D. D. Warrior Lady" is still removed from play even if "Grave Protector" is on the field (if "D. D. Warrior Lady"'s effect is activated). 

If "Banisher of the Light" and "Grave Protector" are both active, destroyed monsters are removed from play.

When there is a face-up "Grave Protector" on the field and a face-down "Desertapir" is attacked, and "Desertapir’s" Flip Effect flips "Grave Protector" face-down, the Desertapir is sent to the Graveyard at the end of the Damage Step instead of to the Deck.

If "Grave Protector" is on the field, the effect of "Slate Warrior" that reduces the ATK and DEF of the monster that destroys "Slate Warrior" is still applied, even though "Slate Warrior" is shuffled back into the Deck instead of being sent to the Graveyard. The timing of "Slate Warrior’s" effect is still at the end of the Damage Step (when monsters are normally sent to the Graveyard after battle).

If "Grave Protector" is on the field when a monster like "Black Luster Soldier - Envoy of the Beginning" or "Great Dezard" (with an effect based on when they destroy a monster in battle) battles and destroys a monster, then the "Great Dezard", etc., still gets the reward for destroying the monster even though the destroyed monster was shuffled into the Deck instead of being sent to the Graveyard.

If "Grave Protector" is on the field, a monster destroyed by "Sword Hunter" is shuffled into the Deck instead of becoming an Equip Spell Card.



GRAVEKEEPER'S ASSAILANT


"Gravekeeper’s Assailant" changes Attack Position to Defense Position or vice-versa. It cannot flip a monster face-down because that is not a change of battle position.

You make the change of battle position due to "Gravekeeper’s Assailant" at the beginning of the attack, so you can change the battle position even if the attack is then negated by "Magic Cylinder", etc.

If "Imperial Order" and "Necrovalley" are both in play, "Necrovalley" is still on the field so you can still activate the effect of "Gravekeeper’s Assailant".

The effect of "Gravekeeper's Assailant" targets 1 monster.

If "Gravekeeper’s Assailant" attacks, and activates its effect to change the battle position of the opponent’s "Spirit Reaper", then "Spirit Reaper" is destroyed by its own effect. Then a replay occurs because the potential attack targets on the opponent's side of the field were changed. In this case, "Gravekeeper’s Assailant" can attack again, and can activate its effect again.

If "Necrovalley" is on the field, an attack is declared with "Gravekeeper’s Assailant", and the effect of "Gravekeeper’s Assailant" is activated, and "Mystical Space Typhoon" is chained to the effect to destroy "Necrovalley", the effect of "Gravekeeper’s Assailant" is still applied because "Necrovalley" only had to be on the field to activate the effect.



GRAVEKEEPER'S CHIEF


You can use the effect of "Gravekeeper’s Chief" to Special Summon the same monster you Tributed to Summon "Gravekeeper’s Chief".

If you Set, Flip Summon, or Special Summon "Gravekeeper’s Chief", its Special Summoning effect is not activated.

If you have "Gravekeeper’s Chief" and "Necrovalley" on the field, you can use "Monster Reborn", "Premature Burial", "Call of the Haunted", etc. to revive monsters from your Graveyard. Also, if you have "Gravekeeper's Chief" on the field, your opponent can use "Monster Reborn" on monsters in your Graveyard.

You cannot activate "The Shallow Grave" while "Necrovalley" is active, even if you control "Gravekeeper’s Chief", because your opponent cannot Special Summon a monster from his Graveyard.

If "Necrovalley" is on the field, and both players control a "Gravekeeper’s Chief", then the Flip Effect of "Fiber Jar" can resolve normally, but if neither, or only 1, player has "Gravekeeper’s Chief", then the Flip Effect of "Fiber Jar" disappears.



GRAVEKEEPER'S SERVANT


If you have 2 of this card on the field, their effects are cumulative.

If your opponent has no cards left in his/her Deck, he/she cannot declare an attack while this card is on your side of the field.



GRAVEKEEPER'S SPY


You can select a Gravekeeper whose ATK would be higher than 1500 after being Summoned. For example, if "Necrovalley" is in play, you can use "Gravekeeper’s Spy" to Special Summon another "Gravekeeper’s Spy", even though its ATK will be 1700 once it is on the field.



GRAVEKEEPER'S VASSAL


The damage that is inflicted to your opponent’s Life Points as a result of battle with "Gravekeeper’s Vassal" attack is treated as effect damage instead, not Battle Damage. So your opponent cannot use "Kuriboh" or "Waboku" to prevent the damage, for example.

A monster destroyed by "Gravekeeper’s Vassal" in battle is still treated as "destroyed as a result of battle" (for "Mystic Tomato", "Nimble Momonga", etc.).

If you equip "Fairy Meteor Crush" to "Gravekeeper’s Vassal", and attack a Defense Position monster and inflict Battle Damage to the opponent’s Life Points, the damage is treated as effect damage due to "Gravekeeper’s Vassal"’s effect.

You cannot activate "Barrel Behind the Door" against damage inflicted by "Gravekeeper’s Vassal" because its effect is a Continuous Effect and you cannot activate "Barrel Behind the Door" against Continuous Effects.



GRAVEKEEPER'S WATCHER


You can activate the effect of "Gravekeeper’s Watcher" to negate "Graceful Charity".

You cannot activate "Gravekeeper’s Watcher" during the Damage Step (such as against a "Morphing Jar" that is flipped by an attack).

You cannot activate "Gravekeeper’s Watcher" when a card is discarded as a cost, such as "Magic Jammer", "Kuriboh", "Tribute to the Doomed", "Thunder Dragon", or "Type Zero Magic Crusher".

You cannot activate "Gravekeeper’s Watcher" against your opponent's "Delinquent Duo" because it makes YOU discard, not your opponent.

You cannot activate "Gravekeeper's Watcher" against the activation of your opponent's "Mirage of Nightmare" because it is possible that your opponent will not have to discard (for example, by having more than 4 cards in his hand).

When "Morphing Jar" is Flip Summoned, you may chain the effect of "Gravekeeper's Watcher", negating the Flip Effect of "Morphing Jar" and destroying it.



GREAT DEZARD


After destroying a second monster, "Great Dezard" still retains his first effect.

If your opponent uses "Double Snare" against "Great Dezard" after "Great Dezard" has achieved his first effect, "Double Snare" is negated and destroyed.

If "Great Dezard" is removed from the field after activating his first effect and then returns to the field, he loses his previously-achieved effect(s).

You can Special Summon only 1 "Fushioh Richie" by Tributing "Great Dezard".

"Great Dezard" can achieve his effects by destroying Monster Tokens.



GREAT MAJU GARZETT


When you use a monster with an original ATK of "?" then "Great Maju Garzett"'s ATK is zero.



GREED


The effect of "Greed" only applies to cards drawn while "Greed" was active. If "Jar of Greed" is chained to "Greed"'s activation, "Jar of Greed" (Step 2) resolves and you draw 1 card for "Jar of Greed" before "Greed"’s effect (Step 1) was active, so no damage is inflicted during the End Phase. But if you chain "Greed" (Step 2) to "Pot of Greed" (Step 1), then "Greed" is active before "Pot of Greed" resolves, so the activator of "Pot of Greed" takes 1000 damage from "Greed".

You can chain to the effect of "Greed" that inflicts damage.



GREENKAPPA


If there is only 1 face-down Spell or Trap Card on the field when the effect of “Greenkappa” is activated, the effect disappears.

You can chain to the effect of “Greenkappa”, even with the targeted Spell or Trap Cards. If only 1 of the 2 cards is chained, “Greenkappa” will still resolve and destroy the other. If “Greenkappa” is destroyed in a chain to its effect (such as with “Torrential Tribute”) its effect still resolves.

Since “Greenkappa” targets, you can use “Fake Trap” to save your Trap Card(s) that were targeted by “Greenkappa”.



GREN MAJU DA EIZA


"Gren Maju Da Eiza"'s effect includes cards removed from play face-down with "Lightforce Sword" or "Different Dimension Capsule".

If you equip "Axe of Despair" to "Gren Maju Da Eiza", calculate its ATK and DEF according to its effect, then add +1000 ATK on top of that.

If "Gren Maju Da Eiza" is equipped with "Megamorph", its ATK is zero, but if "Megamorph" leaves play, recalculate its ATK using its effect.



GRIGGLE


This card’s effect is not activated when equipped to an opponent’s "Relinquished" or "Thousand-Eyes Restrict". 

If your opponent uses "Change of Heart" on a face-down "Griggle" and Flip Summons it, when it returns to you during the End Phase, its effect activates and your opponent will gain 3000 Life Points.



GRYPHON WING


You can chain "Fake Trap" to "Gryphon Wing".



GRYPHON'S FEATHER DUSTER


"Gryphon's Feather Duster" does not destroy itself.

When you destroy multiple cards at the same time with "Gryphon's Feather Duster", you gain the Life Points as 1 "lump sum", so your "Fire Princess" will only do 500 damage.



GUARDIAN ANGEL JOAN


The controller (not the owner) of "Guardian Angel Joan" increases his/her Life Points.

When "Guardian Angel Joan" is destroyed while battling a monster with equal ATK (such as another "Guardian Angel Joan"), her effect is NOT activated because "Guardian Angel Joan" has been removed from the field.

When "Guardian Angel Joan" attacks "Cyber Jar", "Guardian Angel Joan"'s effect is not activated because she is destroyed before "Cyber Jar" is sent to the Graveyard.



GUARDIAN CEAL


The Equip Spell Cards used for "Guardian Ceal"'s effect must be activated and equipped to "Guardian Ceal" by "Guardian Ceal"'s controller in order to be on that player's side of the field.

Sending 1 Equip Spell Card equipped to "Guardian Ceal" to the Graveyard is a cost.

When you send "Big Bang Shot" to the Graveyard for "Guardian Ceal"'s effect, your opponent can chain to this effect, and then "Guardian Ceal" is removed from play.



GUARDIAN ELMA


When you Summon "Guardian Elma", her effect activates and you choose the Equip Spell Card you want. Your opponent can then chain to the effect and, with an effect like "Disappear", can remove the Equip Spell Card so that "Guardian Elma"'s effect disappears.

You cannot equip inappropriate Equip Spell Cards like "Premature Burial" or "Snatch Steal" to "Guardian Elma" with her effect.

You can equip a card with a cost, like "Wicked-Breaking Flamberge - Baou" to "Guardian Elma" with her effect, and you don't have to pay the cost because the Equip Spell Card is not considered "activated".

"Morale Boost"'s effect is applied when you equip "Guardian Elma" with a Spell Card using her effect.



GUARDIAN GRARL


If you wish to use "Guardian Grarl"'s effect to Special Summon him from your hand, you still must have "Gravity Axe - Grarl" on your side of the field.

You cannot Tribute Summon "Guardian Grarl" by Tributing a monster equipped with your only "Gravity Axe - Grarl" on your side of the field, because the "Gravity Axe - Grarl" will no longer be on the field when the Summon occurs.



GUARDIAN KAY'EST


"Guardian Kay'est" is not affected by Spell Cards, just like "The Legendary Fisherman".

Your opponent cannot select "Guardian Kay'est" as the target of an attack.

If "Guardian Kay'est" is your only monster on the field, your opponent can attack your Life Points directly.

As long as "Guardian Kay'est" cannot be selected as the target of an attack, it cannot be targeted by the effect of "Staunch Defender", either.

If "Guardian Kay'est" and another monster are targeted for "Different Dimension Gate", only the other monster is removed from play and returns when "Different Dimension Gate" is destroyed.

If "Guardian Kay'est" and another monster are selected for "Creature Swap"'s effect, "Creature Swap"'s effect is negated because switching is impossible.



GUARDIAN TRYCE


If you Special Summon "Guardian Tryce", you don't get to activate his effect when he's destroyed, even if you Tribute Summoned him previously and are using "Monster Reborn" on him later.

You must Special Summon the exact same card that was Tributed for "Guardian Tryce" when using his effect; you cannot Special Summon a card of the same name.

You cannot use "Guardian Tryce"'s effect to Special Summon a "Special Summon-only" monster that had not been properly Summoned, such as a Fusion Monster that was Special Summoned with "Magical Scientist" and then Tributed for "Guardian Tryce".

You cannot Special Summon "Dark Ruler Ha Des" with "Guardian Tryce"'s effect.

You can Special Summon a monster in your opponent's Graveyard if it was used to Tribute Summon "Guardian Tryce".

If "Guardian Tryce" is an Equip Spell Card equipped to "Relinquished" or "Sword Hunter", and "Guardian Tryce" is destroyed and sent to the Graveyard, his effect activates.

If "Guardian Tryce" is Set and is destroyed, his effect activates.



GUARDIANS


"Guardian Baou", "Guardian Ceal", "Guardian Elma", "Guardian Grarl", "Guardian Kay'est", and "Guardian Tryce" all share some basic rules. Using "Guardian Elma" as an example:

You can Set "Guardian Elma" face-down without "Butterfly Dagger - Elma", but you cannot Special Summon her face-down with "The Shallow Grave", etc., unless you have "Butterfly Dagger - Elma" on your side of the field.

If your Set "Guardian Elma" is flipped face-up with "Swords of Revealing Light", or by an attack, without "Butterfly Dagger - Elma" on your side of the field, she remains on the field because she was not Summoned. 

"Guardian Elma" is a normally Summoned monster, not a Special Summon-only monster. So if Normal Summoned she counts as your 1 Summon for the turn.

You cannot use "Monster Reborn" on "Guardian Elma" if you do not have "Butterfly Dagger - Elma" on your side of the field.

If you activate "Monster Reborn" and target "Guardian Elma" while you have "Butterfly Dagger - Elma" on the field, and your opponent chains "Mystical Space Typhoon" to destroy "Butterfly Dagger - Elma", so that it is no longer on the field when "Monster Reborn" resolves, you cannot Special Summon "Guardian Elma" and "Monster Reborn"'s effect disappears.

You can Normal Summon, Flip Summon, or Special Summon "Guardian Elma" even if your "Butterfly Dagger - Elma" has its effect negated by "Imperial Order".

If "Cyber Jar" resolves and you pick up "Guardian Elma" without "Butterfly Dagger - Elma" on your side of the field, "Guardian Elma" is added to your hand.

These rules apply to all six of these monsters.



GYAKU-GIRE PANDA


When "Gyaku-Gire Panda" is equipped with "Rod of the Mind's Eye" and attacks, the Battle Damage is 1000 points.



GYROID


You cannot choose when to apply “Gyroid’s” effect. If “Gyroid” would be destroyed as a result of battle, its effect is applied (once per turn) whether you want it to be destroyed or not.

If “Gyroid” is destroyed, and is then Special Summoned again that same turn, the effect is reset and its effect will be applied again if appropriate. If “Gyroid” is attacked once, is not destroyed because of its effect, then gets flipped face-down, its effect is reset and will be applied again if attacked that turn.

The effect of “Gyroid” is a Continuous Effect that cannot be chained to (including “Divine Wrath”).

If “Gyroid” is attacked for the first time in a turn by “Dark Ruler Ha Des”, “Gyroid”’s effect is not negated because it will not be destroyed.

If “Gyroid” is equipped with “Heavy Mech Support Platform”, the effect of “Gyroid” will prevent both from being destroyed in battle. If attacked again the same turn and “Gyroid” would be destroyed, “Heavy Mech Support Platform” will be destroyed instead. A third attack will then destroy “Gyroid” normally.

If “Gyroid” is attacked during a Special Battle Phase created by the effect of “Last Turn”, and is then attacked again during the regular Battle Phase, it will be destroyed because its effect was already applied once that turn (during the Special Battle Phase).



HALLOWED LIFE BARRIER


"Hallowed Life Barrier" protects your Life Points from Battle Damage and Effect Damage. It doesn’t protect your monsters from being destroyed as a result of battle.



HAMMER SHOT


"Hammer Shot" determines which monster to destroy using current ATK, not original ATK.

"Hammer Shot" does not target. You determine which monster is destroyed when "Hammer Shot" resolves.



HAND OF NEPHTHYS


"Tribute 2 monsters on your side of the field, including this card" means that you Tribute "Hand of Nephthys" plus 1 additional monster.

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. 

You can chain to the activation of this monster’s effect.

Tributing monsters is a cost of this card’s effect.

You can Tribute a Monster Token as part of this card’s cost.

You can chain to the activation of "Hand of Nephthys’" effect with the effect of "Royal Oppression" to negate the Special Summon of "Sacred Phoenix of Nephthys".



HARPIE LADY 1


The name of "Harpie Lady 1", "Harpie Lady 2", and "Harpie Lady 3" is treated as "Harpie Lady" for all purposes, including Deck construction. So you can have 2 copies of "Harpie Lady 1" in your Deck and 1 copy of "Harpie Lady 2", but not 2 copies of each because you would have 4 cards in your Deck treated as "Harpie Lady". This restriction also applies to your Side Deck, so if you have 3 monsters treated as "Harpie Lady" in your Deck, you cannot have any in your Side Deck.

The effect of "Harpie Lady 1" will increase the ATK of your opponent’s WIND monsters too.



HARPIE LADY 3


For the effect of "Harpie Lady 3" count only your opponent’s turns. If your opponent’s monster attacks "Harpie Lady 3", then count that turn as the first of the two turns. (So the monster could not attack again that turn, even if it had the ability to attack more than once, and it could not attack on your opponent’s next turn either.) If "Harpie Lady 3" attacks your opponent’s monster, then that monster cannot attack for your opponent’s next 2 turns.

If "Element Magician" attacks and destroys "Harpie Lady 3" while there is another WIND monster on the field, "Element Magician" cannot attack again that turn.

If you control "Harpie Lady 3" and "Gemini Elf" and your opponent activates "Change of Heart" to gain control of "Gemini Elf", then attacks your "Harpie Lady 3", your "Gemini Elf" cannot attack for 2 of your opponent’s turns, even after it returns to your side of the field.



HARPIES' HUNTING GROUND


If you control "Harpies’ Hunting Ground" on your side of the field, because it is a Field Spell Card, its effects apply to both players. When either player Normal Summons or Special Summons a "Harpie Lady" or "Harpie Lady Sisters" to the field, the controller of that newly-Summoned monster is the one who selects 1 Spell or Trap Card and destroys it.

You can chain to the effect of "Harpies’ Hunting Ground" that destroys 1 Spell or Trap Card.

The effect of "Harpies’ Hunting Ground" that increases ATK and DEF is applied to all face-up Winged Beast-Type monsters on the field, including your opponent’s, because it is a Field Spell Card.



HARPIE'S PET DRAGON


You count "Harpie Lady" cards on both sides of the field when increasing this card’s ATK and DEF.



HEART OF CLEAR WATER


You may equip this card to a monster with ATK 1300 or greater, but it will be immediately destroyed.

If a monster equipped with this card has its ATK increased over 1299, by the effect of "Rush Recklessly", etc., this card is destroyed.

If your "Relinquished" or "Thousand-Eyes Restrict" is equipped with "Heart of Clear Water" and you its effect to equip it with a Monster Card whose ATK is 1300 or higher, "Heart of Clear Water" is destroyed.

Your monster equipped with "Heart of Clear Water" is not destroyed in battle, but you still take any Battle Damage that would be inflicted to your Life Points by the attack. 

If you Special Summon a monster with "Premature Burial" or "Call of the Haunted" and then equip that monster with "Heart of Clear Water", the monster will not be destroyed if "Premature Burial" or "Call of the Haunted" is destroyed.

A monster equipped with this card can still be destroyed by effects that do not target, such as the effects of "Fissure", "Dark Hole", "Smashing Ground", or "Torrential Tribute".

A monster equipped with this card cannot be destroyed by a card that targets, but it may still be declared a target. So the opponent may activate "Nightmare Wheel" or "Snatch Steal" targeting your monster equipped with "Heart of Clear Water".



HEART OF THE UNDERDOG


Missing the Timing: Suppose you have 3 copies of “Heart of the Underdog” on the field, and draw a Normal Monster Card during your Draw Phase. All 3 copies of “Heart of the Underdog” immediately activate their effects, and because they activate simultaneously, they form a chain with Chain Links 1, 2, and 3. If you draw a Normal Monster card for Chain Link 3 or Chain Link 2, your copies of “Heart of the Underdog” do not activate again. This is because they are “when… you can” optional Trigger Effects, and you “miss the timing” because you drew the Normal Monster Card during a chain and not as Chain Link 1. However, if you draw a Normal Monster Card for Chain Link 1, all 3 copies of “Heart of the Underdog” will activate their effects again.

“Heart of the Underdog” doesn’t only activate if you draw a Normal Monster Card for your standard draw. It will also activate its effect if you draw a Normal Monster Card with a card effect such as “Reload”, “Jar of Greed”, or “Heart of the Underdog”. 

When you draw a Normal Monster Card, if you want to activate the effect of “Heart of the Underdog” you have to show it to your opponent immediately. You can’t do anything else in between.

A Normal Monster Card means a yellow card with no effect. A Ritual Monster with no effect is not a Normal Monster Card. A card like “Blue-Eyes Toon Dragon” is not a Normal Monster Card.

When you show a Normal Monster Card to your opponent to activate “Heart of the Underdog”, your opponent can chain “Drop Off”. You will have to discard that Normal Monster Card, but “Heart of the Underdog” still resolves its effect.

If you draw multiple cards at the same time during your Draw Phase, such as with “Reload”, only 1 of the cards needs to be a Normal Monster to trigger “Heart of the Underdog”, since they are all drawn at the same time. If you activate “Reload” in your Draw Phase and draw 5 Normal Monster Cards, your “Heart of the Underdog” only activates 1 time because it says “card(s)”.



HEAVY MECH SUPPORT PLATFORM


Note that "Heavy Mech Support Platform" is different from other Union Monsters in that its last sentence is applied if the monster it is equipped to is destroyed (period), not just when the monster is destroyed as a result of battle. This extra effect does not apply to previous Union Monsters.

If a monster equipped with "Heavy Mech Support Platform" is targeted by "Ring of Destruction", then "Heavy Mech Support Platform" is destroyed instead of the equipped monster, and the damage inflicted to both players by "Ring of Destruction" is 0 (because the monster targeted by "Ring of Destruction" was not destroyed by it).

If you have a monster, "X-Head Cannon" for example, equipped with "Heavy Mech Support Platform", and you activate "Limiter Removal", the ATK will becomes (1800 + 500) x 2 = 4600. Also, the "Heavy Mech Support Platform" will be destroyed instead of the "X-Head Cannon" during the End Phase (by the effect of "Limiter Removal").

If "Heavy Mech Support Platform" is equipped to "Big Core" or "Reflect Bounder" and they would be destroyed by their effect, "Heavy Mech Support Platform" is destroyed instead.

If “Reflect Bounder” equipped with “Heavy Mech Support Platform” is attacked by “Dark Ruler Ha Des”, during damage calculation “Heavy Mech Support Platform” is destroyed instead of “Reflect Bounder”. Then, after damage calculation, “Reflect Bounder” will destroy itself by its own effect. Its effect is not negated, because it was not destroyed by “Dark Ruler Ha Des”.



HELPING ROBO FOR COMBAT


When "Helping Robo For Combat" destroys a monster in battle, you resolve the effect of "Helping Robo for Combat" before the destroyed monster is sent to the Graveyard.



HELPOEMER


When you have multiple "Helpoemer" cards in your Graveyard, each with an activated effect, the effects are cumulative.

If your opponent chooses not to conduct a Battle Phase, there is no timing for the end of the Battle Phase, so the effect of "Helpoemer" is not activated. The same is true if the Battle Phase is skipped due to a card effect.

"Helpoemer" cannot be Special Summoned from the Graveyard even if it was not destroyed as a result of battle (the final sentence on "Helpoemer" is a condition, not an effect, and is not subject to the first sentence on "Helpoemer").



HIDDEN BOOK OF SPELL


If you have zero or 1 Spell Cards in your Graveyard, you cannot activate "Hidden Book of Spell".

When you activate "Hidden Book of Spell" and your opponent chains "Disappear" or "Graverobber", and 1 of the targeted Spell Cards is removed from play, the remaining Spell Card goes back to the Deck and the Deck is shuffled.



HIEROGLYPH LITHOGRAPH


"Hieroglyph Lithograph" does not remain on the field like "Swords of Revealing Light".

The effect of "Hieroglyph Lithograph" cannot be negated by "Imperial Order" after "Hieroglyph Lithograph" has resolved. You can, of course, chain "Imperial Order" to the activation of "Hieroglyph Lithograph" to negate the effect.

When "Infinite Cards" and "Hieroglyph Lithograph" are both in effect, there is no limit to the number of cards for your hand.



HIITA THE FIRE CHARMER


If your opponent chains “Enemy Controller” to the activation of the Flip Effect of a “Charmer”, and takes control of the “Charmer”, the Flip Effect disappears.

If you take control of the opponent’s monster with a “Charmer” and the opponent takes control back with “Change of Heart”, control still reverts to you after the effect of “Change of Heart” expires (even though it wasn’t your monster originally).

If your opponent takes control of your monster with “Snatch Steal”, and you activate the Flip Effect of a “Charmer” to take it back, you keep control while the “Charmer” is face-up on the field.

If “Book of Moon” is chained to the Flip Effect of a “Charmer” to flip the target monster face-down, the effect of the “Charmer” disappears.

If a “Charmer” is removed from play with “Interdimensional Matter Transporter”, its effect is not re-applied when it’s back on the field.

If “DNA Transplant” changes a monster’s Attribute so that it can be taken by a “Charmer”, and then “DNA Transplant” is destroyed so that the monster’s Attribute no longer corresponds to the effect of the “Charmer”, the controller of the “Charmer” loses control of the monster.

If the turn player controls a “Charmer” and a monster controlled by its effect, and activates “Assault on GHQ” and targets the controlled monster, and the opponent chains an effect to destroy the “Charmer”, the controlled monster returns to the opponent’s control, but is still destroyed by the effect of “Assault on GHQ”.



HINO-KAGU-TSUCHI


When your "Hino-Kagu-Tsuchi" inflicts Battle Damage to your opponent, he / she discards his / her hand before drawing in their next Draw Phase. If their next Draw Phase is skipped, they discard at the start of the Standby Phase. If the Draw Phase and Standby Phase are skipped, they discard at the start of Main Phase 1.

The opponent cannot activate any effects at the start of their turn before they discard their hand for the effect of "Hino-Kagu-Tsuchi".



HOMUNCULUS THE ALCHEMIC BEING


This monster’s effect is a Ignition Effect.

If you use this monster’s effect to change its Attribute, it remains changed as long as it remains face-up on the field, or until it is changed again.



HORN OF LIGHT


If a "Sangan" or a "Witch of the Black Forest" equipped with "Horn of Light" is Tributed and you activate the effect of "Horn of Light", "Horn of Light" 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 "Horn of Light" are simultaneous and form a chain.



HORUS' SERVANT


"Horus’ Servant" has an effect just like "Lord of D.", but only applicable to "Horus the Black Flame Dragon". "Horus’ Servant" will not negate a card effect. All it does is prevent "Horus the Black Flame Dragon" from being selected as a target. If your opponent selects "Horus the Black Flame Dragon" as a target (with "Ring of Destruction", for example), and you chain "Call of the Haunted" to Special Summon "Horus’ Servant", then "Horus the Black Flame Dragon" will still be destroyed by "Ring of Destruction" because "Horus’ Servant" is being Special Summoned AFTER "Horus the Black Flame Dragon" was selected. The fact that "Ring of Destruction" has not yet resolved does not matter; "Horus the Black Flame Dragon" was selected at activation of "Ring of Destruction", and "Horus’ Servant" is Special Summoned too late to prevent this.

Your opponent cannot activate a Spell Card, Trap Card, or Monster Effect that would select "Horus the Black Flame Dragon" as a target while "Horus’ Servant" is in play. "Horus’ Servant" does not cause the effect to be negated; he prevents the activation of the effect in the first place.



HORUS THE BLACK FLAME DRAGON LV4


The "you" in "on your side of the field" is the current controller’s field, so as long as "Horus the Black Flame Dragon LV 4" is face-up, it is always "face-up on your side of the field".

If "Horus the Black Flame Dragon LV 4" destroys a monster, you can activate its effect during the End Phase, even if the destroyed monster was your monster that was controlled by your opponent.

If you don’t have "Horus the Black Flame Dragon LV 6" in your hand or Deck, you can still send "Horus the Black Flame Dragon LV 4" to the Graveyard to activate its effect. But if you don’t have "Horus the Black Flame Dragon LV 6" then your opponent can check your Deck to confirm.

If "Horus the Black Flame Dragon LV 4" destroys a monster as a result of battle, and is removed from play by "Interdimensional Matter Transporter", and returns to play during the End Phase, you can still activate its effect.

"If Banisher of the Light" is in play, you cannot send "Horus the Black Flame Dragon LV 4" to the Graveyard, so you cannot activate its effect.

You don’t have to send "Horus the Black Flame Dragon LV 4" to the Graveyard if you don’t want to, even if it destroyed a monster as a result of battle. But if you activate its effect by sending it to the Graveyard, you must Special Summon "Horus the Black Flame Dragon LV 6" if possible.

You can activate the effect of "Horus the Black Flame Dragon LV 4" during your opponent’s End Phase if appropriate.

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.



HORUS THE BLACK FLAME DRAGON LV6


The "you" in "on your side of the field" is the current controller’s field, so as long as "Horus the Black Flame Dragon LV 6" is face-up, it is always "face-up on your side of the field".

You cannot Tribute "Horus the Black Flame Dragon LV 6" for "Ectoplasmer"’s effect because it is not a cost, it is a Tribute when you resolve "Ectoplasmer"’s effect, and "Horus the Black Flame Dragon LV6" is not affected by Spell Cards’ effects.

If "Horus the Black Flame Dragon LV6" is equipped with "Metallizing Parasite - Lunatite", and would be destroyed as a result of battle, "Metallizing Parasite - Lunatite" is destroyed instead (this is not negated by "Horus the Black Flame Dragon LV6"’s effect).

If "Horus the Black Flame Dragon LV 6" is the only monster on the field, you can activate a Spell Card that targets, but its effect will be negated because "Horus the Black Flame Dragon LV 6" would be the only valid target and it is unaffected by Spell Cards.

You can activate "Level Up!" and send "Horus the Black Flame Dragon LV 6" to the Graveyard to Special Summon "Horus the Black Flame Dragon LV 8" because sending 1 monster to the Graveyard is a cost for "Level Up!" and if a card is unaffected by Spell Cards, that only refers to effects, not to costs.

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.



HORUS THE BLACK FLAME DRAGON LV8


Note that "Horus the Black Flame Dragon LV8" has the word "except" in its Summoning conditions, which means that even if Special Summoned properly, you cannot revive it with "Monster Reborn" afterwards if it is destroyed.

The "you" in "on your side of the field" is the current controller’s field, so as long as "Horus the Black Flame Dragon LV 8" is face-up, it is always "face-up on your side of the field".

The ability of "Horus the Black Flame Dragon LV8" to negate Spell Cards is a multi-trigger effect that must be chained to the activation of the Spell Card. You can activate this effect multiple times in the same chain to negate the activation and effect of several Spell Cards that are activated in the same chain.

You can chain the effect of "Horus the Black Flame Dragon LV8" to the activation of a Continuous Spell Card, Field Spell Card, or Equip Spell Card and negate it. However, if the Continuous, Field, or Equip Spell Card is already active, you cannot later decide to try and negate its effect with "Horus the Black Flame Dragon LV8". You can only negate it when it is originally activated.

You can activate the effect of "Horus the Black Flame Dragon LV8" during the Damage Step.



HUGE REVOLUTION


When your opponent chains "Book of Moon" to your "Huge Revolution" and flips 1 of the 3 monsters face-down, "Huge Revolution" has already been activated correctly so the effect of "Huge Revolution" resolves.

When your opponent chains "Ring of Destruction" to your "Huge Revolution" and destroys 1 of the 3 monsters, "Huge Revolution" has already been activated correctly so the effect of "Huge Revolution" resolves.

"Huge Revolution" destroys both face-up and face-down cards.

If your opponent activates "Huge Revolution" and you have "Pandemonium Watchbear" and "Pandemonium", your "Pandemonium" card is not destroyed.



HUMAN-WAVE TACTICS


"Human-Wave Tactics" includes Tokens.

If you have 2 "Human-Wave Tactics" then both effects are applied, so if 1 Level 2 or lower Normal Monster is destroyed in battle, then you Special Summon 2 monsters.

If your monster is destroyed as a result of battle while on your opponent's side of the field, you can't get the effect of "Human-Wave Tactics" for that monster. 

If you don't have enough vacant Monster Card Zones to Special Summon as many monsters as you need to for "Human-Wave Tactics", Special Summon as many as you can, and the rest are destroyed. This is also true for multiple "Human-Wave Tactics", so if you have 2 "Human Wave Tactics", and each wants to Summon 2 monsters, and you only have 3 Zones, Special Summon 3 monsters and destroy 1 monster.



HYENA


Because the effect of “Hyena” activates in the Graveyard, the owner of “Hyena” gets the effect. So if your opponent controls your “Hyena” and it is destroyed, you get the effect.

You can Special Summon more than 1 “Hyena” using this effect.




HYPER HAMMERHEAD


"Hyper Hammerhead"'s effect activates at the time that a monster would be sent to the Graveyard.

Even if "Hyper Hammerhead" was destroyed, its effect resolves.

The effect of "Hyper Hammerhead" can be chained to.

If you have another effect that activates at the end of the Damage Step, you can place it on a chain with "Hyper Hammerhead"'s effect (such as "Hyper Hammerhead" vs. "Hyper Hammerhead").



INABA WHITE RABBIT


This card can only attack Life Points directly. It cannot attack another monster. If the opponent controls "Patrician of Darkness" and you attack with "Inaba White Rabbit", it is still a direct attack; they cannot select a monster as the attack target.

However, if the opponent controls a monster equipped with "Ring of Magnetism", your "Inaba White Rabbit" must attack the equipped monster if you chose to attack.



INFERNO


When "Inferno" battles with another monster with equal ATK, "Inferno"'s effect is not activated because it must destroy the other monster "and send it to the Graveyard", and at that time, Inferno is no longer on the field to activate its effect.

If "Inferno" attacks a face-down "Cyber Jar", "Inferno" is destroyed by the effect of "Cyber Jar" and "Inferno"'s effect is not activated.



INFERNO FIRE BLAST


No copies of "Red-Eyes B. Dragon" can attack if you activate "Inferno Fire Blast".

If "Red-Eyes B. Dragon" attacked, you cannot activate "Inferno Fire Blast" during Main Phase 2, but if "Red-Eyes B. Dragon" did not attack, you can activate "Inferno Fire Blast" during Main Phase 2.

As long as a "Red-Eyes B. Dragon" is on the field when you activate "Inferno Fire Blast", "Inferno Fire Blast" still resolves normally even if "Red-Eyes B. Dragon" is no longer on the field when "Inferno Fire Blast" resolves.

If you control "Red-Eyes B. Dragon" and activate "Inferno Fire Blast" to inflict damage, and then after that resolves you activate "Non-Spellcasting Area", "Red-Eyes B. Dragon" still cannot attack because "Non-Spellcasting Area" will not negate the condition.

If "Imperial Order" is chained to "Inferno Fire Blast", the effect of "Inferno Fire Blast" is negated but "Red-Eyes B. Dragon" cannot attack. However, if "Magic Jammer" negates the activation of "Inferno Fire Blast", your "Red-Eyes B. Dragon" can attack.

If you activate "Inferno Fire Blast" while "Non-Spellcasting Area" is active, the effect of "Inferno Fire Blast" disappears.

If you only have 1 "Red-Eyes B. Dragon" on the field, you can activate multiple copies of "Inferno Fire Blast" designating that same "Red-Eyes B. Dragon".

If "Red-Eyes B. Dragon" equipped with "Megamorph" is selected for "Inferno Fire Blast", you inflict 2400 damage to the opponent.



INFERNO TEMPEST


If you attack "Blue-Eyes White Dragon" with "Ojama Green" or some other 0 ATK monster, you can activate "Inferno Tempest" after damage calculation. Then "Ojama Green" is sent to the Graveyard after "Inferno Tempest" resolves.



INJECTION FAIRY LILY


You can activate this card’s effect during both players’ Damage Steps, at damage calculation. You can activate it only once per Damage Step, but if "Injection Fairy Lily" is involved in multiple battles in the same turn, you can activate it once during each battle.

You cannot increase this card’s ATK by 6000 points by paying 4000 Life Points.

The ATK increase only lasts for that 1 Damage Step. If this card is involved in multiple battles during the same turn, you must pay 2000 Life Points each battle if you wish to keep increasing its ATK.

Activating this card’s effect does not cause a replay.

You may activate this card’s effect even when it is attacking directly.

If your "Injection Fairy Lily" is in battle with the opponent’s "Injection Fairy Lily" the turn player must decide to use its effect or not first. The opponent can then activate their "Injection Fairy Lily" effect. If both effects are activated, it forms a chain.

If this card is equipped with "Heart of Clear Water" and you activate its effect to increase its ATK, the "Heart of Clear Water" is immediately destroyed.

The effect of "Mirror Wall" will reduce "Injection Fairy Lily"’s ATK by half before you decide to use its effect or not. So if you activate its effect, its ATK will be 3200. If 2 copies of "Mirror Wall" are active, its ATK will be 3100.



INSECT PRINCESS


While "Insect Princess" is on your side of the field, if you attack your opponent's face-down Insect-Type monster, it is changed to Attack Position after being flipped face-up (before damage calculation).

While "Insect Princess" is on your side of the field, your opponent can change the Battle Position of his Insect-Type monsters once during his turn, but the Battle Position is immediately changed back to Attack Position.

When you have "Insect Princess" and a Defense Position "Crass Clown" on your side of the field, and "DNA Surgery" is making "Crass Clown" an Insect-Type, and your opponent takes control of "Crass Clown" with "Change of Heart", "Crass Clown" is changed to Attack Position because of "Insect Princess"' effect and its effect activates.

"Insect Princess" gains 500 ATK if she destroys an Insect-Type Monster Token.



INSECT QUEEN


Insect Monster Tokens are placed during the End Phase for each monster "Insect Queen" destroyed that turn (1 for 1).

Insect Monster Tokens are placed during the End Phase, not during the Battle Phase when "Insect Queen" destroys a monster.

The Insect Monster Token is Special Summoned to the side of the field of the player who controls "Insect Queen" at the time the Insect Monster Token is Summoned, even if control of "Insect Queen" changed between the Battle Phase and the End Phase.

If "Insect Queen" destroys a monster but is not on the field during the End Phase, no Insect Monster Token is Special Summoned.

No Insect Monster Token is Special Summoned if it is impossible (due to "Jam Breeding Machine", etc.).

If you want to use "Royal Oppression" to negate the Special Summon of an Insect Monster Token, you chain it to the activation of "Insect Queen"’s effect during the End Phase.

If you Tribute "Pinch Hopper" to attack with Insect Queen, you can activate "Pinch Hopper"’s effect.



INTERDIMENSIONAL MATTER TRANSPORTER


A monster removed with "Interdimensional Matter Transporter" doesn't occupy a Monster Card Zone. If there are no Monster Card Zones available when it returns, it is destroyed.

If you control your opponent's monster because of "Change of Heart" or "Snatch Steal", and remove the monster with "Interdimensional Matter Transporter", the monster returns to your side of the field, then immediately returns to your opponent's side of the field.

A monster returned to the field because of "Interdimensional Matter Transporter" returns in the same Battle Position that it was in when it was removed from the field.

If a Spirit Monster is returned to the field with "Interdimensional Matter Transporter" the same turn it was Summoned or flipped face-up, it returns to the field and then returns to the owner's hand.

When a Fusion Monster is returned to the field with "Interdimensional Matter Transporter" the same turn it was Special Summoned with "Summoner of Illusions" or "Magical Scientist", the Fusion Monster is not destroyed or returned to the Fusion Deck.

When an Archfiend is returned to the field with "Interdimensional Matter Transporter" after it was Special Summoned with "Archfiend's Roar", it is not destroyed by "Archfiend's Roar"'s effect.

When "Karate Man", or a monster affected by "Limiter Removal", is removed from play with "Interdimensional Matter Transporter", it is not destroyed that turn because the effect of "Karate Man"/"Limiter Removal" is reset.



INVADER OF DARKNESS


"Invader of Darkness" prevents the activation of Quick-Play Spell Cards, but doesn't negate their effects. So if your opponent activates a Quick-Play Spell Card and you chain "Call of the Haunted" to Special Summon "Invader of Darkness", he does not negate the activation or effect of the Quick-Play Spell Card.



INVASION OF FLAMES


The effect of this monster prevents the activation of Trap Cards that can be activated when a monster is Normal Summoned, such as "Trap Hole" and "Torrential Tribute".

You can activate Trap Cards later in the turn.

You can negate the Normal Summon of this monsters with "Horn of Heaven" or "Solemn Judgment". (In which case the Normal Summon failed and the effect of the monster is not applied.)

The effect of this monster is applied to both players (so you cannot activate "Pineapple Blast" in response to your Normal Summon of this monster).

This is a Continuous Effect that you cannot chain to.



JADE INSECT WHISTLE


The monster selected for "Jade Insect Whistle" is chosen when the effect resolves, not when it is activated, so "Jade Insect Whistle" doesn't target.

If your opponent claims to have no Insect-Type monsters in his/her Deck when your "Jade Insect Whistle" resolves, you can check the Deck to make sure.

A face-up "Parasite Paracide" can be selected with "Jade Insect Whistle".



JAM BREEDING MACHINE


If you have two "Jam Breeding Machines" on your side of the field you cannot Summon any monsters, even Slime Tokens.

You may Set monsters when you have this card active on your side of the field, but you cannot Flip Summon them.

You may Summon a monster and then activate this card.

You cannot activate "Scapegoat" if you have this card active on your side of the field.

If the effect of "Cyber Jar" is activated when you have this card active on your side of the field, monsters that you pick up which could normally be Summoned by the effect of "Cyber Jar" are destroyed instead. Other monsters, such as Level 5 and above monsters, and monsters that can only be Special Summoned, are still added to your hand.



JAM DEFENDER


If you have two "Revival Jams" on the field, you may redirect an attack to either one of your choosing.

If you have "Jam Defender", "Revival Jam", and a monster equipped with your "Ring of Magnetism" on your side of the field, you may redirect an attack to "Revival Jam" when you opponent attacks the monster equipped with "Ring of Magnetism".



JAR ROBBER


You can chain "Jar Robber" to your own or your opponent's "Pot of Greed".

The only way to activate "Jar Robber" is to chain it to the activation of "Pot of Greed".

"Jar Robber" must be the very next step in the chain, so if you activate "Pot of Greed" and your opponent chains "Imperial Order", you cannot activate "Jar Robber".



JETROID


Both players can chain to the Trap Card that is activated by the effect of “Jetroid” (the controller can activate several Trap Cards from his hand in a chain).

If “Ancient Gear Golem” attacks “Jetroid”, the controller of “Jetroid” cannot use its effect.



JOWGEN THE SPIRITUALIST


When playing with this card you need to remember which monsters on the field were Special Summoned because they can later be destroyed with the effect of "Jowgen the Spiritualist". If a monster that was Special Summoned is flipped face-down, it can still be destroyed by the effect of "Jowgen the Spiritualist".

While this card is on the field neither player can activate "Scapegoat", "Monster Reborn", "Call of the Haunted", "Magical Hats", "Dedication through Light and Darkness", or any other card that Special Summons a monster.

If "Jowgen the Spiritualist" is Special Summoned by the effect of "Cyber Jar", all monsters that are Special Summoned by that "Cyber Jar" are Summoned successfully.



JOWLS OF DARK DEMISE


When "Jowls of Dark Demise" is flipped and its effect activates during your opponent's turn, it ends at the end of your opponent's turn. You take control of a monster, but can’t attack with it because it isn’t your turn.

You can take control of a face-down monster with "Jowls of Dark Demise".

You can Tribute a monster you took control of with "Jowls of Dark Demise".
.
If you take control of a Union Monster with "Jowls of Dark Demise", and equip it to your monster, control of the Union Monster Card does not return to your opponent at the end of the turn because it is an Equip Spell Card.



JUDGMENT OF ANUBIS


You can activate "Judgment of Anubis" when there are no monsters on your opponent's side of the field.

When you activate "Judgment of Anubis", you destroy your opponent's monster after the activation and the effect of the Spell Care are negated. This means that the monster-destroying effect of "Judgment of Anubis" does not target.

You can activate "Judgment of Anubis" and select a Spell Card that destroys only a Spell Card (like "De-Spell") or only a Trap Card (like "Remove Trap") or could destroy both (like "Mystical Space Typhoon") or many (like "Heavy Storm").

You can activate "Judgment of Anubis" and select a Spell Card that negates the activation of a card and destroys it, like "My Body as a Shield" or "Bait Doll".

You cannot activate "Barrel Behind the Door" against "Judgment of Anubis" because when "Judgment of Anubis" is activated, it has not been confirmed that the damage-inflicting effect will happen.



JUDGMENT OF THE DESERT


You can still change the Battle Positions of monsters with card effects; "Judgment of the Desert" only prevents "manual" changes.



KA-2 DES SCISSORS


The Level of the destroyed monster is the original Level.

You can use "Barrel Behind the Door" against "KA-2 Des Scissors"' effect.



KAIBAMAN


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.



KAISER COLOSSEUM


Your opponent can still Flip Summon a monster.

If there are already more monsters on your opponent's side of the field when you activate "Kaiser Colosseum", nothing happens to your opponent's monsters but your opponent cannot Summon any more. Also, if the number of monsters controlled by "Kaiser Colosseum"'s controller is reduced, the opponent does not have to remove any of his monsters.

Your opponent cannot use "Monster Reborn", "Scapegoat", etc. while "Kaiser Colosseum" prevents him from placing new monsters. However, your opponent CAN use "Change of Heart", "Snatch Steal", etc.

If all monsters of "Kaiser Colosseum"'s controller are destroyed, "Kaiser Colosseum"'s effect no longer functions until that player has at least 1 monster again (when the effect re-activates).

If the player who controls "Kaiser Colosseum" has his only monster taken by the opponent with "Change of Heart", then the opponent can place more monsters because "Kaiser Colosseum"'s effect is no longer active until the player has at least 1 monster again.

When "Kaiser Colosseum" is active, and "Cyber Jar" is activated, if your opponent would control more monsters than you, your opponent has to destroy monsters equal to the difference; the excess monsters are never actually Summoned and instead are sent from the Deck to the Graveyard (so "Witch of the Black Forest" does not get its effect, etc.). So the monsters are destroyed after they are picked up, but before any monsters are Special Summoned for the effect of "Cyber Jar".



KAISER GLIDER


The "same ATK" as "Kaiser Glider" means the same as the current ATK, not the original ATK.

When "Kaiser Glider" is in Attack Position and battles a monster with the same ATK, only the other monster is destroyed.

"Kaiser Glider"'s second effect activates when destroyed and sent to the Graveyard from the field, hand, or Deck.

If "Kaiser Glider" is equipped to "Relinquished" or "Thousand-Eyes Restrict", and is destroyed and sent to the Graveyard, "Kaiser Glider"'s effect activates.



KAMINOTE BLOW


The effect of “Kaminote Blow” that destroys monsters at the end of the Damage Step is not part of a chain.



KANGAROO CHAMP


If you attack “Kangaroo Champ” with “Berserk Gorilla” while “Final Attack Orders” is on the field, “Berserk Gorilla” is changed to Defense Position due to “Kangaroo Champ”, and is destroyed by its own effect before it can be changed to Attack Position again.

If “Kangaroo Champ” attacks a Flip Effect Monster, “Kangaroo Champ” is Step 1 of the chain and the Flip Effect Monster is Step 2.

If your opponent’s monster is destroyed during damage calculation then you cannot apply the effect of “Kangaroo Champ”.

The effect of “Kangaroo Champ” can be chained to. After damage calculation, it starts a new chain.




KARATE MAN


If "Karate Man" is equipped with "Megamorph" and its ATK is being halved, if you then activate its effect, its ATK is 2000. If you activate its effect and then equip it with "Megamorph" while your Life Points are greater than your opponent’s, its ATK is 500. If "Karate Man" is equipped with "Megamorph" and you activate its effect, or if you activate its effect and then equip it with "Megamorph" while your Life Points are less than your opponent’s, its ATK is 2000.



KAZEJIN


A marker may be placed on this card to indicate that its effect has been used. The effect resets if the monster is destroyed or removed from the field. 

You can use the effect of this card even if it is face-down when it is attacked because its effect is activated during the Damage Step, and it will be face-up at that point. 

The effect of this card targets.



KELDO


You cannot activate "Keldo"'s effect when there are not at least 2 cards in your opponent's Graveyard.

The owner of the Deck shuffles it and the controller of "Keldo" cuts the Deck.



KING DRAGUN


The first effect of “King Dragun” is a Continuous Effect. The second effect of “King Dragun” is an Ignition Effect.

Your opponent cannot target a Dragon-Type Fusion Monster with “De-Fusion” while “King Dragun” or “Lord of D.” is on the field because “De-Fusion” targets.

“Divine Wrath” is NOT a card that targets, so “Divine Wrath” may be used against Dragon-Type monsters while “King Dragun” or “Lord of D.” is on the field.

You can chain “Divine Wrath” to the effect of “King Dragun” that Special summons a Dragon-Type monster.




KING OF THE SKULL SERVANTS


The original ATK of “King of the Skull Servants” is determined by its effect. This is further doubled/halved by “Megamorph” and other effects that are based off of original ATK. If the number of “Skull Servant” and “King of the Skull Servants” cards in your Graveyard changes, re-calculate the original ATK of “King of the Skull Servants”, then re-apply the effect of “Megamorph”. If you have “King of the Skull Servants” with an original ATK of 2000 (2 “Skull Servant” cards in your Graveyard), and you equip it with “Megamorph”, its original ATK will be 4000 when your Life Points are lower, and 1000 when your Life Points are higher.

Since the ATK of this card is ?, it cannot be Special Summoned by the effect of "Mystic Tomato".

Removing from play 1 “Skull Servant” or “King of the Skull Servants” to Special Summon a “King of the Skull Servants” is a cost.



KING OF THE SWAMP


You can only get 1 copy of "Polymerization" when you discard "King of the Swamp" from your hand.

You can activate the effect of "King of the Swamp" even if all 3 of your "Polymerization" cards are in your Graveyard.

If "King of the Swamp" is selected for the effect of "Prohibition", you cannot use either of its effects.

Discarding this card is a cost.

If you use "King of the Swamp" as Fusion Material from your hand, you do not get to activate its effect to search your Deck for "Polymerization".



KING TIGER WANGHU


Monsters with ATK 1400 or less that are already on the field when "King Tiger Wanghu" is Summoned are not destroyed. "King Tiger Wanghu"’s effect only applies to monsters Summoned while it is face-up on the field.

When a monster is Flip Summoned or flipped face-up by a card effect, it is not destroyed by the effect of "King Tiger Wanghu".

"King Tiger Wanghu"’s effect applies to both sides of the field.

When "King Tiger Wanghu" is Special Summoned by the effect of "Cyber Jar", other monsters with ATK 1400 or less that are Special Summoned by the same "Cyber Jar" are destroyed if they are Special Summoned in face-up Attack Position.

If a monster’s ATK when it is Summoned is less than 1400 due to the effect of other cards, such as a Field Spell Card that reduces its ATK, it is destroyed by "King Tiger Wanghu"’s effect (so apply all existing modifiers before determining if the monster is destroyed). If "Command Knight" is Summoned, it increases its own ATK to 1600 before "King Tiger Wanghu" can destroy it.

If "King Tiger Wanghu" is Normal Summoned or Special Summoned, and its own ATK is reduced below 1400 by a pre-existing effect, then it destroys itself when Summoned. (Example: "King Tiger Wanghu" and "Bladefly" are Special Summoned simultaneously by "Cyber Jar". "King Tiger Wanghu"’s ATK is 1300, and it is destroyed by its own effect (and "Bladefly" is also destroyed by "King Tiger Wanghu"’s effect).

Monsters that are Summoned face-down (like with "The Shallow Grave") are not destroyed by King Tiger Wanghu.

"King Tiger Wanghu"’s effect includes Monster Tokens with ATK 1400 or less.

If "King Tiger Wanghu" is on the field and "Marauding Captain" is Summoned, "Marauding Captain" can still activate its effect and Special Summon a monster even though "Marauding Captain" is destroyed.

If "King Tiger Wanghu" is on the field along with Trigger Effect monsters such as "Mysterious Puppeteer", "Ryu-Kishin Clown", "Sonic Bird", and "Dragon Seeker", then they form a chain.

If "King Tiger Wanghu" is on the field, and "Exiled Force" is Summoned, "King Tiger Wanghu"’s effect immediately activates. Since "Exiled Force" cannot be chained, "King Tiger Wanghu" will destroy "Exiled Force" before the turn player can Tribute "Exiled Force" using its effect.



KIRYU


While "Mask of Restrict" is active, you cannot Tribute "Kiryu" because "Mask of Restrict" prevents all Tributing, including Tributing Equip Spell Cards.

If you Tribute "Kiryu" while it is equipped to "Dark Blade", you cannot then use "Super Rejuvenation" and count "Kiryu" as a Dragon-Type monster.

If you Tribute "Kiryu" while equipped to "Dark Blade", "Dark Blade" no longer gets the ATK increase from "Kiryu" as it is no longer equipped with it.



KISHIDO SPIRIT


If your monster in Defense Position is attacked by a monster with equal ATK to your monster's ATK, your Defense Position monster will not be destroyed even if its DEF was lower than the attacking monster's ATK.

When "Spear Dragon" attacks a Defense Position monster with equal ATK to "Spear Dragon", perform damage calculation normally even though the Defense Position monster is not destroyed.



KOITSU


"Koitsu"'s effect that inflicts damage is only applied to a monster that is equipped with "Koitsu" by "Koitsu"'s effect; "Koitsu" itself, while a monster, does not receive this effect.



KOTODAMA


Sheep Tokens will be destroyed by the effect of "Kotodama" since Monster Tokens are considered cards.

If two Flip Effect monsters are flipped face-up at the same time while "Kotodama" is on the field, their effects are negated and they are destroyed. 

If 2 or more monsters with identical names are on the field when "Kotodama" is Summoned, they are all destroyed.



KOZAKY'S SELF-DESTRUCT BUTTON


You cannot activate “Kozaky’s Self-Destruct Button” because it has no activation effect.

If “Bait Doll” targets “Kozaky’s Self-Destruct Button”, nothing happens because the timing is inappropriate. However, “Kozaky’s Self-Destruct Button” is then destroyed by “Bait Doll”.

“Kozaky’s Self-Destruct Button” starts a chain at the time that it is sent to the Graveyard. If “Banisher of the Light” is on the field and “Kozaky’s Self-Destruct Button” is removed from play, its effect still activates because it only has to be destroyed.



KRYUEL


If "Second Coin Toss" is active, and "Kryuel" is sent to the Graveyard as a result of battle, you can re-do the coin toss.



KURIBOH


"Kuriboh" does not target the attacking monster.

"Kuriboh" only prevents Battle Damage to your Life Points; it will not prevent your monsters from being destroyed.

"Kuriboh" can only be activated while in your hand, its effect cannot be used while "Kuriboh" is on the field.

Using "Kuriboh" is a Multi-Trigger effect.

"Kuriboh" is activated during damage calculation. If your opponent attacks with "Injection Fairy Lily" and activates her effect, you can chain "Kuriboh" to reduce the damage to zero.
