Dark Requiem Xyz Dragon Yugioh OCG

"3 Level 5 monsters
If this card has "Dark Rebellion Xyz Dragon" as Xyz Material, it gains these effects.
● Once per turn: You can detach 1 Xyz Material from this card, then target 1 face-up monster your opponent controls; its ATK becomes 0, and if it does, this card gains ATK equal to that monster's original ATK.
● During either player's turn, when your opponent activates a monster effect: You can detach 1 Xyz Material from this card; negate the activation, and if you do, destroy that monster, then you can Special Summon 1 Xyz Monster from your Graveyard."
