Fantôme du Chaos GLAS-FRSE1

The damage your opponent takes from a battle involving this card becomes 0. Once per turn, you can target 1 Effect Monster in your Graveyard, banish that target, and if you do, until the end of this turn, this card's name and ATK become the name and ATK of that monster, and it gains that monster's effects. You must control this card face-up to activate and resolve this effect.
