When a monster's attack is negated: Activate 1 of these effects;
●It becomes the End Phase of this turn.
●Target 1 "Utopia" Xyz Monster you control; its ATK becomes double its original ATK until the end of this turn.
If a "Utopia" Xyz Monster you control would detach exactly 1 Xyz Material to activate its effect, you can banish this card from your Graveyard instead.
