Chaos Number 32: Shark Drake Vice

EFFECT:

4 Level 4 WATER monsters
You can also Xyz Summon this card by using a "Number 32: Shark Drake" you control as the Xyz Material. (Xyz Materials attached to that monster also become Xyz Materials on this card.) During either player's turn: You can detach 1 Xyz Material from this card and banish 1 monster from your Graveyard to target 1 face-up monster on the field; that target's ATK and DEF become 0 until your next End Phase. You must have 1000 Life Points or less to activate and to resolve this effect.
