During either player's turn, you can remove 1 Xyz Material from this card, then choose 1 of your opponent's Fusion, Synchro, or Xyz Monsters that are removed from play and return it to the Extra Deck, then destroy 1 monster your opponent has in play with the same monster card type (Fusion, Synchro, or Xyz).
