Once per turn, during either player's turn, if a card(s) you control would be destroyed by battle or by a card effect while this card has Xyz Material: You can activate this effect; it is not destroyed, also you can destroy 1 face-up card your opponent controls. If this card has "Number 74: Master of Blades" as an Xyz Material, it gains this effect. ● During either player's turn: You can detach 1 Xyz Material from this card to target 1 card on the field; until the end of this turn, when any of your opponent's card effects resolve that targeted that card at activation, negate those effects.
