Pay 800 LP, then target 1 "Exorsister" monster you control; Special Summon from your Extra Deck, 1 "Exorsister" Xyz Monster with a different name from the cards you control, by using that monster you control as material. (This is treated as an Xyz Summon. Transfer its materials to the Summoned monster.) You can only activate this card during your opponent's turn, unless your opponent controls a monster Special Summoned from the GY. You can only activate 1 "Exorsister Amento" per turn.
