You can activate only 1 card with this card’s name per turn.
(1) When a monster effect is activated: Detach 1 material from a DARK Xyz Monster you control; negate that activation, and if you do, destroy it, then, if the material you detached to activate this card was originally a “The Phantom Knights”, “Raidraptor”, or “Xyz Dragon” card, 1 “Raidraptor” Xyz Monster you control gains ATK equal to the original ATK of the monster destroyed by this effect.
