Once per turn: You can target 1 other face-up Attack Position monster on the field; attach it to this card as a face-up Xyz Material. Once per turn, during either player's turn, when a card or effect is activated: You can detach 1 Xyz Material from this card; negate the activation, and if you do, destroy it.
