For Raidraptors! And one last surprise from Kurosaki’s signature Deck.

Rank-Up-Magic Battle Up Force
Quick-Play Spell Card
(1) When your opponent attacked: Target 1 “Raidraptor” Xyz Monster you control; Special Summon from your Extra Deck, 1 “Raidraptor” monster that is 2 Ranks higher than that target, by using that target as the Xyz Material. (This Special Summon is treated as an Xyz Summon. Xyz Materials attached to that target also become Xyz Materials on the Summoned monster.)

Kurosaki evolves his his Raidraptor – Rise Falcon into Raidraptor – Revolution Falcon using Battle Up Force. And the second twist is Kurosaki uses Rank-Up-Magic Doom Double Force to Xyz Summon an unrevealed Rank 12 Raidraptor monster.
