Light Wing Shield

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.
