Forum:Stellarknight Constellar Diamond VS Burning Abyss

Situation: Stellarknight Constellar Diamond destroys (by battle) a rank 3 monster that has Graff and Cir as xyz materials. My question is, can he negate the activation of both of their effects, or just the last one that activated? (since his ruling states that this quick effect must be chained directly to the activation of a DARK monster's effect)
