Pendulum Xyz
Target 2 cards in your Pendulum Zones; Special Summon both targets, but negate their effects, then, immediately after this effect resolves, Xyz Summon 1 Xyz Monster using only those 2 monsters. When you do, you can treat the Level of 1 of the monsters the same as the other monster's. You can only activate 1 "Pendulum Xyz" per turn.
