Forum:Assault Counter vs. Stardust Dragon

If my opponent has Stardust Dragon on the field and I control an Assault Mode monster and I activate a card to destroy cards on my opponent's side of the field and he activates Stardust's effect to negate my card, can I activate Assault Counter to negate the Stardust's effect and destroy it or could he save it? Thanks. Mastermind6656 05:56, 8 March 2009 (UTC)
