Forum:Shooting Quasar Dragon vs Steelswarm Roach

If Player A summons Quasar and Player B responds to the summon with Steelswarm Roach's Effect, can Player A activate Quasars effect to negate that card? I'm not sure whether that works or not since Roach responds to the summon, where Quasar is (theoretically) not yet on the field. --.·:BronzeJohnson:·. (talk • contribs) 18:12, November 11, 2014 (UTC)
