Card Rulings:Chaos Emperor Dragon - Envoy of the End


 * "Chaos Emperor Dragon - Envoy of the End" sends itself to the Graveyard as part of its effect, and counts itself for determining how much damage it inflicts.


 * The damage that "Chaos Emperor Dragon - Envoy of the End" inflicts is equal to the number of cards BOTH players send to the Graveyard times 300 points.


 * "Barrel Behind the Door" and "Trap of Board Eraser" can be chained to "Chaos Emperor Dragon - Envoy of the End"'s effect. "Barrel Behind the Door" is, itself, sent to the Graveyard by "Chaos Emperor Dragon - Envoy of the End"'s effect and counts for an additional 300 points as a result.


 * If "Chaos Emperor Dragon - Envoy of the End" is destroyed or removed from play by an effect chained to its own effect, its effect still resolves.


 * Tokens will be removed from the field by "Chaos Emperor Dragon - Envoy of the End"'s effect, but will not add to the damage total because they are not sent to the Graveyard.


 * It is the controller, not the owner, of "Chaos Emperor Dragon - Envoy of the End" that can activate its effect and that inflicts damage to his/her opponent.


 * If you control your opponent's "Chaos Emperor Dragon - Envoy of the End" and you pay the 1000 Life Points, the effect inflicts damage to your opponent even though the monster returns to your opponent's Graveyard.


 * If "Chaos Emperor Dragon - Envoy of the End" is Special Summoned, and the controller immediately activates its effect, and the opponent chains "Torrential Tribute" as Step 2 of a chain, "Torrential Tribute" destroys all monsters on the field and sends them to the Graveyard, then "Chaos Emperor Dragon - Envoy of the End"'s effect resolves, sends all Spell & Trap Cards on the field to the Graveyard[, and inflicts 300 points of damage to the opponent for each Spell & Trap Card sent to the Graveyard by its effect. (Monster Cards do not count toward the damage because they were destroyed and sent to the Graveyard in the middle of the chain by "Torrential Tribute".)


 * If "Waboku" is chained to the effect of "Chaos Emperor Dragon - Envoy of the End", it will not prevent the damage because "Waboku" only applies to Battle Damage. Also, "Waboku" will still be on the field when "Chaos Emperor Dragon - Envoy of the End"'s effect is applied, so it will still count for 300 points of damage to the opponent.


 * When "Minar" and "Electric Snake" are sent to the Graveyard by "Chaos Emperor Dragon - Envoy of the End", their effects are not activated because the modified text on those cards says when they are "discarded to the Graveyard from the hand".

Mentions in Other Rulings

 * Barrel Behind the Door: You can activate "Barrel Behind the Door" against Ignition Effects like..."Chaos Emperor Dragon - Envoy of the End".


 * Big Burn: You can only activate "Big Burn" when an EFFECT that removes monsters in the Graveyard is activated. So you can't activate "Big Burn" when a player removes monsters in the Graveyard as a COST to Special Summon..."Chaos Emperor Dragon - Envoy of the End"...


 * Chosen One: You may not select a monster that can only be Special Summoned by a specific effect for this card's effect, such as a Ritual Monster, "Chaos Emperor Dragon - Envoy of the End"... If the only Monster Card in your hand is a monster such as these, then you cannot activate "Chosen One".


 * D.D. Scout Plane: If "D.D. Scout Plane" is destroyed by "Dark Ruler Ha Des" and then removed from play to Special Summon "Chaos Emperor Dragon - Envoy of the End", "D.D. Scout Plane"'s effect activates and it will be Special Summoned.


 * Dimension Fusion: "Dimension Fusion" cannot Special Summon a "Special Summon-only" monster, like..."Chaos Emperor Dragon - Envoy of the End", unless it was properly summoned first.


 * Elephant Statue of Blessing, Elephant Statue of Disaster: "Elephant Statue of Blessing"'s effect activates when sent from the hand to the Graveyard by the effect of..."Chaos Emperor Dragon - Envoy of the End".


 * Enemy Controller: When the Ignition Effect of..."Chaos Emperor Dragon - Envoy of the End" is activated, and you chain "Enemy Controller" to take control of the..."Chaos Emperor Dragon - Envoy of the End", even if you take control of the monster, you cannot take control of the effect itself. So if your opponent activates..."Chaos Emperor Dragon - Envoy of the End"'s effect, and you chain "Enemy Controller", you still take the damage from..."Chaos Emperor Dragon - Envoy of the End".


 * Last Turn: You cannot Special Summon a monster for "Last Turn" that is a "Special Summon-only" monster like "Chaos Emperor Dragon - Envoy of the End"... Nor can you select a Spirit Monster because they cannot be Special Summoned.


 * Skill Drain: Conditions for Summoning monsters is not negated by "Skill Drain", so you still must remove 1 DARK and 1 LIGHT monster to Special Summon "Chaos Emperor Dragon - Envoy of the End"...


 * The End of Anubis: "The End of Anubis" WILL NOT negate the Special Summon of "Chaos Emperor Dragon - Envoy of the End"...
