​Drawing a card is not optional. You must draw 1 card any time "Airknight Parshath" inflicts Battle Damage to the opponent’s Life Points. This includes direct attacks, and when it battles with a monster with a lower ATK or DEF.

If the opponent activates "Waboku" or "Kuriboh" to reduce the Battle Damage to 0, you do not draw.

When "Airknight Parshath" attacks a face-down monster with a Flip Effect and inflicts Battle Damage, you draw 1 card before the Flip Effect is applied. 

​The effect of “Amazoness Chain Master” is optional. You choose whether or not to activate it when this monster is destroyed as a result of battle and sent to the Graveyard.

Here’s the proper sequence for “Amazoness Chain Master”:
1. When this card is destroyed and sent to the Graveyard as a result of battle, choose to activate its effect or not.
2. If you choose to activate the effect, pay 1500 Life Points and activate it. Then see if your opponent wants to chain to the effect.
3. After the chain is resolved (if any), resolve the effect.
3A. Look at your opponent’s hand and choose 1 Monster Card. If there are no Monster Cards, the effect disappears.
3B. Add the Monster Card you chose to your hand. Now you can use it like your monster.

If you get your opponent’s monster with “Amazoness Chain Master” and it’s placed on the field, and later returned to the hand with “Penguin Soldier”, it returns to the original owner’s hand.

You cannot activate the effect of “Amazoness Chain Master” if your opponent has no hand.

If you have your opponent’s monster that you acquired with “Amazoness Chain Master”, and your opponent activates “Disturbance Strategy”, the monster returns to the owner’s Deck. However, you draw the same number of cards that you had in your hand, including 1 card for the monster you acquired with “Amazoness Chain Master”.

If you acquired your opponent’s monster with “Amazoness Chain Master”, and “Remove Brainwashing” is activated, the monster returns to the original owner if it is on the field. However, if it’s still in your hand then it is not returned.

If you acquire your opponent’s monster with “Amazoness Chain Master” and your opponent uses “Lightforce Sword” on it, it returns to your hand (not the owner’s hand) after the effect of “Lightforce Sword” expires.

If “Ancient Gear Golem” attacks, the effects of Spell or Trap Cards that are already face-up can still have their effects activated, like “Ultimate Offering”, “Royal Oppression”, or “Skull Lair”. However, face-down Spell or Trap Cards cannot be activated (flipped face-up), including a face-down “Ultimate Offering”, etc.

The effect of “Ancient Gear Golem” that prevents your opponent from activating Spell or Trap Cards is a Continuous Effect. It cannot be chained to. “Divine Wrath” cannot be activated against it.

If “Ancient Gear Golem” attacks, and is destroyed before the end of the Damage Step, its effect is no longer applied after it is destroyed, even if it is still on the field and has not yet been sent to the Graveyard. (A Continuous Effect is no longer applied after the monster generating it has been destroyed, even if the monster is still on the field.) The effect of “Ancient Gear Golem” is applied up until the point it is destroyed, though. 

If you Special Summon "Apprentice Magician" face-down (such as with "Apprentice Magician’s” effect) then you do not place a Spell Counter.

An active "Skill Drain" can negate the effects of the "D.D. Warrior Lady," "D.D. Assailant," and "Apprentice Magician." But "The End of Anubis" has no effect on them, because they are on the field when their effects activate AND they do not target any card(s) in the Graveyard.

If a stolen Apprentice Magician is sent to the Graveyard by battle, the current controller of the card gets to search his deck for its effect.

You must show your opponent the monster you Special Summon.

For effects that place a Spell Counter, you can chain to the activation of those effects. The Spell Counter is actually placed when the effect resolves.

​"Asura Priest" may attack directly if it has not already attacked a monster this turn.

"Asura Priest" cannot attack a monster if it has already attacked directly this turn. For example, the opponent activates "Call of the Haunted" or "Scapegoat" after "Asura Priest" has completed a direct attack.

"Asura Priest" may attack each monster only once. If the opponent controls "Spirit Reaper" you cannot continually attack it.

When cards like "Gravekeeper’s Servant" or "Toll" are active on the field, you must pay each time "Asura Priest" attacks.

"Asura Priest" attacks each monster one a time. Resolve the battle with one monster before declaring an attack on another monster.

"Asura Priest" does not have to attack all monsters on your opponent’s side of the field. If you opponent controls 3 monsters, you may choose to attack only 2 of them.

When "Asura Priest" attacks and destroys "Giant Rat" or "Masked Dragon", you may then attack the monster Special Summoned by the effect of those monsters.

If “Asura Priest” attacks a monster and your opponent activates “Magic Cylinder” to negate the attack, “Asura Priest” can attack that same monster again.

If your opponent has “Patrician of Darkness” on the field they can choose the same monster as the attack target of “Asura Priest” each time you declare an attack with it. (For example, re-direct all of your “Asura Priest” attacks at “Spirit Reaper” instead.)

After "Asura Priest" has attacked monsters, other monsters you control may still attack directly.

"Asura Priest" can attack each monster once during the same Battle Phase. These attacks do not have to be all in a row. For example, you can attack monsters with "Asura Priest", then attack with another monster, and "Asura Priest" can still attack again as long as it attacks a monster it has not attacked yet.

If you remove Monster Cards from your Graveyard to increase the ATK of "Bazoo the Soul-Eater", then on your opponent’s turn he uses "Change of Heart" to gain control of the same "Bazoo the Soul-Eater", your opponent can remove cards from his Graveyard to further increase the ATK. The ATK increase you caused will end during that End Phase, and the ATK increase your opponent caused will end during your End Phase.

Removing Monster Cards from the Graveyard is a cost of "Bazoo the Soul-Eater"’s effect, so if your opponent chains to the activation of this effect with "Call of the Haunted", to Special Summon "Kycoo the Ghost Destroyer", the effect of "Bazoo the Soul-Eater" is not negated since the Monster Cards were already removed.

When the monster equipped with "Big Bang Shot" is destroyed, and "Big Bang Shot" is destroyed as a result of this, the equipped monster is not removed from play.

The effect of "Big Bang Shot" that removes the equipped monster from play can be resolved between steps of a chain. For example, if "Change of Heart" targets a monster equipped with "Big Bang Shot", and "Mystical Space Typhoon" is chained to "Change of Heart" to destroy "Big Bang Shot", first resolve "Mystical Space Typhoon" and destroy "Big Bang Shot", then remove the monster that was equipped from play, and THEN resolve "Change of Heart" (and the effect of "Change of Heart" disappears).

If a monster equipped with "Big Bang Shot" is flipped face-down, it is no longer a target of "Big Bang Shot" so "Big Bang Shot" is sent to the Graveyard and the monster is not removed from play.

When "Imperial Order" is active, and you destroy "Big Bang Shot" with "Dust Tornado", the effect of "Big Bang Shot" that would remove the monster from play is NOT applied.

When you send "Big Bang Shot" to the Graveyard with "Emergency Provisions", the monster is removed from play at the same time.

When equipped to "Guardian Ceal", if you send "Big Bang Shot" to the Graveyard as a cost for "Guardian Ceal"'s effect, "Guardian Ceal" is removed from play but "Guardian Ceal"'s effect still resolves.

If a monster is equipped with "Big Bang Shot" and "Fiber Jar" is activated, both "Big Bang Shot" and the equipped monster are shuffled into the Deck, and the equipped monster is not removed from play even though "Big Bang Shot" was removed from the field.

If you equip your "Big Bang Shot" to your opponent's "Dark Magician", and "Dark Magician" attacks your "Giant Soldier of Stone", the opponent of the owner of the "Big Bang Shot" takes the damage (so your opponent, who attacked with "Dark Magician", takes 900 points of damage.)

The battle damage caused when the equipped monster attacks a Defense Position monster is considered to come from the equipped monster, not from "Big Bang Shot". So a "Don Zaloog" equipped with "Big Bang Shot" could still make the opponent discard 1 card when attacking a face-down monster with low DEF.

If you Special Summon a monster with "Premature Burial", and equip it with "Big Bang Shot", and "Heavy Storm" is activated, the effects of "Premature Burial" and "Big Bang Shot" form a chain, with the controller of the 2 cards determining the order in which they are placed on the chain, and the order in which they are resolved. If the controller chooses "Big Bang Shot" to be Step 2, then the monster will be removed from play. If the controller chooses "Premature Burial" to be Step 2, then the monster will be destroyed and sent to the Graveyard.

A face-down "Big Shield Gardna" can only negate a Spell Card that targets 1 face-down monster, so it cannot negate "Riryoku", "Creature Swap" or "Dark Hole", but could negate "Nobleman of Crossout" or "Tribute to the Doomed".

If "Big Shield Gardna" is targeted with a Spell Card, you may chain "Book of Moon" to flip it face-down, then it can negate the Spell Card and will flip back to face-up Defense Position.

"Skill Drain" only negates the effects of monsters that are face-up on the field, so a face-down "Big Shield Gardna" may still negate a Spell Card that targets it while "Skill Drain" is active on the field. It will still be flipped to face-up Defense Position, and now its effect that changes its battle position when it is attacked will be negated.

If "Prickle Fairy" attacks a face-down "Big Shield Gardna" both their effects will occur at the end of the Damage Step. "Prickle Fairy" will be Step 1 and "Big Shield Gardna" Step 2. So it will change to Attack Position, and then the effect of "Prickle Fairy" will change it back to Defense Position.

​

​"Black Luster Soldier - Envoy of the Beginning" is treated as a different card from "Black Luster Soldier". So you can have 3 copies of "Black Luster Soldier - Envoy of the Beginning" and 3 copies of "Black Luster Soldier" in your Deck & Side Deck combined.

"Black Luster Soldier - Envoy of the Beginning" can remove itself from play using its first effect.

The first effect of "Black Luster Soldier - Envoy of the Beginning" can be activated during your Main Phase 1 or 2. The second effect can be activated during your Damage Step in your Battle Phase, and can be chained to.

If you activate "Black Luster Soldier - Envoy of the Beginning"'s first effect, and "Skill Drain" is chained to it to negate the effect, or if "Skill Drain" was active before you activated the effect, you cannot attack with "Black Luster Soldier - Envoy of the Beginning" that turn because the activation of the effect was not negated and the condition that is included will not be negated by "Skill Drain".

If you use the first effect of "Black Luster Soldier - Envoy of the Beginning", then remove him from play and return him to play, or destroy him and Special Summon him again, or flip him face-down then face-up again, you can activate his effect again that same turn.

If "Black Luster Soldier - Envoy of the Beginning" attacks, and its attack is negated by "Magic Cylinder" or "Negate Attack", you cannot activate his first effect during Main Phase 2.

When a card is removed from play by "Black Luster Soldier - Envoy of the Beginning"'s first effect, it is removed from play face-up.

If "Black Luster Soldier - Envoy of the Beginning" destroys your opponent's only monster with his first attack, he can attack your opponent directly for the second attack.

If "Black Luster Soldier - Envoy of the Beginning" attacks and destroys your opponent's monster, then attacks a second time and destroys another monster, it does not get to attack any more that turn.

Even if you equip him with "Twin Swords of Flashing Light - Tryce", "Black Luster Soldier - Envoy of the Beginning" only gets a maximum of 2 attacks.

When "Black Luster Soldier - Envoy of the Beginning" conducts a second attack using his second effect, his effect activates during the first attack's Damage Step, and the attack is declared in the next Battle Step. The second attack must come consecutively after the first attack; other monsters' attacks cannot come in-between.

If you control "Blade Knight" and a face-down monster on your side of the field, "Blade Knight"’s second effect is not applied because you control another monster (whether it is face-up or face-down is not important).

If you have two "Blade Knights", then their second effects are not applied because for each one, you have another monster on the field besides the "Blade Knight".

If "Blade Knight" destroys a Flip Effect Monster like "Slate Warrior", even that monster’s non-Flip effects are negated. So in this case, "Slate Warrior" does not reduce the ATK and DEF of the "Blade Knight" that destroyed it, because "Blade Knight" negates its effect.

If "Blade Knight" destroys "The Immortal of Thunder", its effect is negated. If your opponent had already gained the 3000 Life Points, then your opponent does not lose the 5000 Life Points. If "Blade Knight" attacked "The Immortal of Thunder" while it was face-down, your opponent neither gains nor loses Life Points from "The Immortal of Thunder"’s effect.

If "Blade Knight" destroys "Spear Cretin", "Spear Cretin"’s effect is not applied.

The effect of a Flip Effect monster destroyed by "Blade Knight" is negated while the destroyed card is in the Graveyard. If the monster is Set again on the field, then the Flip Effect is activated when it’s flipped again.

If "Blade Knight" attacks a face-down Attack Position Flip Effect Monster with equal ATK, and both monsters are destroyed, then "Blade Knight"’s effect is applied because it destroyed the monster, and the monster’s effect is negated. 

When you activate "Book of Moon" during the Battle Step to flip your defending monster into face-down Defense Position, the attack resolves as normal. No replay occurs because the possible attack targets on your side of the field did not change.

When you activate "Book of Moon" during the Battle Step to flip an attacking monster into face-down Defense Position, the attack stops. No replay is triggered. The attacking monster cannot change its battle position in Main Phase 2, because it is still considered to have declared an attack. (So it cannot be Flip Summoned in Main Phase 2.)

If you are attacking, and you chain "Book of Moon" to your opponent’s "Mirror Force" to flip one of your monsters face-down, that monster is not destroyed by "Mirror Force".

If you chain "Book of Moon" to "Magic Cylinder", "Ring of Destruction", or "Trap Hole" to flip the target of any of those cards face-down, the card’s effect disappears. (See "Activation & Targeting Eligibility" in the Advanced FAQ.)

If you use "Book of Moon" on a monster that had its ATK doubled with "Limiter Removal", the monster is not destroyed at the end of the turn.

If you chain "Book of Moon" to "Bottomless Trap Hole", the now face-down monster will not be destroyed by "Bottomless Trap Hole", but any other appropriate monsters Summoned at the same time will still be destroyed.

If you use "Book of Moon" on "Dream Clown", "Dream Clown"’s effect is not activated.

If you chain "Book of Moon" to the activation of a Flip Effect Monster’s effect, such as "Fiber Jar", "Book of Moon" flips the monster face-down again, but the Flip Effect still resolves as normal.

You cannot flip a Monster Token face-down because Monster Tokens are always face-up.

You cannot activate "Book of Moon" while "Light of Intervention" is active.

​Flipping a monster into face-up Attack Position with "Book of Taiyou" is NOT a Flip Summon.

When a Flip Effect Monster is flipped face-up by the effect of "Book of Taiyou", its Flip Effect is activated. You can Set a monster and use "Book of Taiyou" on it that same turn; its Flip Effect will activate. 

If the monster targeted by “Brain Control” is flipped face-down later in the turn, it is still returned back to the original controller in the End Phase.

You cannot activate “Brain Control” if you already have 5 monsters on your side of the field. 

Placing a Spell Counter on "Breaker, the Magical Warrior" is a chain that begins after it is Summoned. If your opponent chains "Trap Hole" or "Ring of Destruction" to the placement of a Spell Counter on "Breaker, the Magical Warrior", "Trap Hole" / "Ring of Destruction" resolves before the Spell Counter is placed on "Breaker, the Magical Warrior", so you cannot chain "Breaker, the Magical Warrior"'s effect.

"Breaker, the Magical Warrior"'s effect is Spell Speed 1 so you cannot chain it to the activation of a Spell Card.

You can use "Breaker, the Magical Warrior"'s effect multiple times in the same turn as long as you can keep re-supplying him with Spell Counters (using "Pitch-Black Power Stone", etc.).

Removing a Spell Counter is a cost; if you remove a Spell Counter from "Breaker, the Magical Warrior" and your opponent chains "Ring of Destruction", the Spell Counter has already been removed so "Ring of Destruction" deals 1600 damage to each player; "Breaker, the Magical Warrior"'s effect that destroys a card is still applied even though "Breaker, the Magical Warrior" himself has been destroyed at that point.

If I chain "Ring of Destruction" to the placement of a Spell Counter on "Breaker, the Magical Warrior", "Ring of Destruction" does 1600 damage to each player because the action of placing the Spell Counter has not resolved.

​Discarding your hand is not a cost for either player.

A player can activate “Card Destruction” even if they would draw more than the remaining cards in their Deck. (In this case, they would lose the Duel.)

If your opponent uses "Monster Reborn" to Special Summon a monster from your Graveyard, you get to draw a card.

If the Special Summon is negated with "Horn of Heaven" or "Solemn Judgment" you do not get to draw a card.

Drawing a card for this card’s effect is optional, so if you use "Call of the Haunted" when you have no cards left in your Deck you do not lose the Duel. 

You can activate "Chain Disappearance" in response to your own Summon of a monster, in which case your opponent still removes all cards with that name from his hand and Deck.

If you use "Chain Disappearance" in response to a Flip Summon, any Flip Effects like "Penguin Soldier" would still resolve. The Flip Effect is Step 1 of the chain, and "Chain Disappearance" is step 2.

The effect of "Chain Disappearance" can remove multiple monsters that are Summoned simultaneously, for example if your opponent activates "Scapegoat", you can respond with "Chain Disappearance" to remove all 4 "Sheep Tokens" that were Special Summoned from the field.

If your opponent activates "Chain Disappearance" and you chain "Ring of Destruction", "Ring of Destruction" resolves first and destroys the monster and sends it to the Graveyard, and there is no monster of the same name so no cards are removed from play for the effect of "Chain Disappearance". If you chain “Book of Moon”, the monster will be face-down, so no cards are removed from play for the effect of “Chain Disappearance”.

If you use “Chain Disappearance” when a Fusion Monster is Special Summoned, remove from play that Fusion Monster plus all copies of that Fusion Monster in the Fusion Deck.

You can only activate "Chaos Sorcerer"'s effect during Main Phase 1 or 2 of your turn.

You can only activate "Chaos Sorcerer"'s effect once in a turn.

If "Chaos Sorcerer" attacks, you cannot use its effect during Main Phase 2. But if "Chaos Sorcerer" did not attack, you can activate its effect in Main Phase 2.

If you select a face-up monster with "Chaos Sorcerer"'s effect, and your opponent chains "Book of Moon" to flip the monster face-down, then "Chaos Sorcerer"'s effect disappears. But even if "Chaos Sorcerer"'s effect disappears, its effect was activated so it cannot attack or activate its effect again.

If "Chaos Sorcerer" attacks and the attack is negated with "Magic Cylinder", "Chaos Sorcerer" cannot activate its effect in Main Phase 2.

If "Chaos Sorcerer" attacks and a replay occurs, and you decide not to attack again with "Chaos Sorcerer", you cannot activate "Chaos Sorcerer"'s effect in Main Phase 2.

"Creature Swap" does not target. The monsters are chosen when its effect resolves, not when "Creature Swap" is activated.

The opponent cannot chain "Fairy’s Hand Mirror", "Riryoku Field", or "Shift" to "Creature Swap" because it does not target. For the same reason, "Lord of D." does not prevent Dragon-Type monsters from being selected, and "Freed the Matchless General" will not negate the effect of "Creature Swap".

Both players must have at least 1 eligible monster on the field for "Creature Swap" to be activated. If the opponent chains a card (such as "Ring of Destruction") to destroy the only monster on one side of the field, the effect of "Creature Swap" disappears.

Monsters affected by "Creature Swap" do not return to their owner’s control at the end of the turn, they stay under the opponent’s control until removed from the field or a card effect such as "Remove Brainwashing" says otherwise.

The battle position of monsters affected by "Creature Swap" may be changed by card effects the turn "Creature Swap" was activated.

A player may select a monster that had its battle position changed earlier in the turn (manually or by card effect).

A player may select a Monster Token.

A player may select a monster Special Summoned by "Call of the Haunted" or "Premature Burial". If the "Call of the Haunted" or "Premature Burial", still on the opponent’s side of the field, is destroyed, the monster targeted by those cards is destroyed also.

A player may select a monster that is equipped with "Snatch Steal". The original owner of the creature, who now controls the creature again, will still gain 1000 Life Points each turn from the opponent’s "Snatch Steal" card as long as it remains on the field.

A player may activate "Change of Heart" to gain control of an opponent’s monster, and then activate "Creature Swap" and select that monster to return to the opponent. At the end of the turn, the monster targeted by "Change of Heart" does not switch sides again since it is already on the owner’s side of the field. 

​Spirit Monsters, Toon Monsters, Ritual Monsters, etc. are sent to your hand as they cannot be Special Summoned or must be Special Summoned is a specific way.

Both players reveal all 5 cards to each other, and then the turn player may Special Summon his monsters, then the opponent. After revealing the cards, you may shuffle them around so you can Special Summon monsters face-down without the opponent knowing which monster is which. 

If "Sangan" or "Witch of the Black Forest" was destroyed by "Cyber Jar"’s effect, Special Summon monsters first and then complete "Sangan"’s effect.

If you attacked your opponent’s face-down "Cyber Jar," after its effect resolves you can then attack with any monsters you Special Summoned in Attack Position before you enter your Main Phase 2.

"Torrential Tribute" can be used on monsters Summoned by "Cyber Jar" but not if "Cyber Jar" was flipped face-up in the Damage Step, since "Torrential Tribute" cannot be activated during the Damage Step.

If a player has less than 5 cards in their Deck, they do not lose (since you are picking-up cards, not drawing), they pick up however many cards they have and continue with "Cyber Jar"’s effect.

​You can't activate "D. D. Designator" if you have no cards in your hand, or if "D. D. Designator" is the only card in your hand.

If you have your opponent's card in your hand because of "Exchange", you can remove it from play if you name a card your opponent doesn't have in his hand.

You declare the card name when you activate "D. D. Designator".

If your opponent has no cards in his hand when "D. D. Designator" resolves, the effect of "D. D. Designator" is negated.

You can't activate "D. D. Designator" when your opponent has no cards in his hand.

If you activate "D. D. Designator" and your opponent has 2 copies of the same card in hand, you (the player who activated "D. D. Designator") select which of the 2 cards is removed from play (this can be important if your opponent holds your card because of "Exchange").

​You don't have to activate "D. D. Warrior Lady"'s effect if you don't want to.

When your “D. D. Warrior Lady” attacks your opponent's “Fiber Jar”, if you activate her effect then “Fiber Jar” is Step 1 of the chain, because it is mandatory, and “D. D. Warrior Lady” is Step 2 of the chain because it is an optional effect. "D. D. Warrior Lady” removes from play both monsters, and then resolve the effect of “Fiber Jar”. “D. D. Warrior Lady” and “Fiber Jar” are not shuffled into the Deck.

When your “D. D. Warrior Lady” attacks “Wall of Illusion”, if you activate her effect then “Wall of Illusion” is Step 1 of the chain, because it is mandatory, and “D. D. Warrior Lady” is Step 2 of the chain because it is an optional effect. The effect of “D. D. Warrior Lady” removes from play both monsters, then the effect of “Wall of Illusion” disappears, since the attacking monster is no longer on the field.

If your "D. D. Warrior Lady" attacks your opponent's "D. D. Warrior Lady", your "D. D. Warrior Lady" is Step 1 of the chain and your opponent's is Step 2, and when Step 2 resolves, both "D. D. Warrior Lady" cards are removed from play and your "D. D. Warrior Lady"'s effect disappears.
