Raidraptor's Phantom Knights Claw

Counter Trap

When a monster effect is activated: Detach 1 material from your DARK Xyz Monster; negate the activation, and if you do, destroy that card, then if the detached material was a "The Phantom Knights", "Raidraptor", or "Xyz Dragon" card, 1 "Raidraptor" Xyz Monster you control gains ATK equal to that destroyed monster's original ATK. You can only activate 1 "Raidraptor's Phantom Knights Claw" per turn.
