Forum:Negation

Alright, my opponent has 1 facedown s/t and one Evolzar Dolkka.

I have Brionac, Dragon of the Ice Barrier on the field and The Fabled Catsith in hand.

I activate Brionac's effect, discarding The Fabled Catsith, and target his facedown s/t for Brionac's effect. For Catsith's effect, I target his Dolkka.

Question now is : Which effect can my opponent negate? Brionac, Catsith, both or neither? Thanks. Xopiel (talk • contribs) 13:42, June 23, 2012 (UTC)
