You cannot target a non-effect monster, nor can you target a Gemini monster.
This effect targets 1 Effect Monster in your GY.
The target is removed from play when this effect resolves.
(1) Any Battle Damage this monster inflicts to your opponent becomes 0. (2) Once per turn, you can remove from play 1 Effect Monster in your GY. Until the End Phase, this card's name is treated as that monster's name, and it gains that monster's effect(s) and ATK.
The (1) Continuous Effect applies so long as this card is face-up on the field.
The (2) Ignition Effect activates & resolves on the field.
If this effect removes the target from play, Phantom of Chaos gains its name, ATK, and effect(s).
Phantom of Chaos will not gain the category of TUNER, etc. [REF], nor will it gain any Conditions (ex: if Debris Dragon is copied, you CAN use Phantom of Chaos for the Synchro Summon of a non-Dragon-Type Synchro Monster, the other Synchro Material Monsters may be Level 4) [REF].
If the target is removed from play before this effect resolves, Phantom of Chaos does not gain any traits of the target, nor can it activate its effect again that turn [REF].
You decide when this lingering effect expires during the End Phase (like with Brain Control).
VS. Relinquished: If Phantom of Chaos copies the name, ATK, and effects of Relinquished and equips an opponent's monster, the equipped monster is destroyed during the End Phase [REF].
VS. Prohibition: if a card is named, and later Phantom of Chaos copied its name, ATK, and effects, then it cannot attack, change its Battle Position, etc.
VS. Skill Drain: If you use Phantom of Chaos' effect to copy the name, ATK, and effect(s) of a DARK monster and afterwards Skill Drain is activated, the copied effect(s) are negated, but the copied name and ATK are not negated. If you activate Phantom of Chaos' effect and Skill Drain is chained, the target is not removed from play, and the effect resolves negated.
