Once per turn, during either player's turn: You can detach 1 Xyz Material from this card; you cannot Special Summon monsters for the rest of this turn, also your opponent randomly chooses 1 card in your Extra Deck, and if it is a "Number" monster with "Number 1" through "Number 99" in its name, Special Summon it from your Extra Deck, by using this face-up card you control as the Xyz Material. (This Special Summon is treated as an Xyz Summon. Xyz Materials attached to this card also become Xyz Materials on the Summoned monster.) During the End Phase, banish the face-up monster Special Summoned by this effect.
