Forum:Summoning effect and Stardust

If you Summon Enishi, Shien's Chancellor, and your opponent activates Bottomless Trap Hole, you can't use effect to chain to bottomless, right? Only Summoning effects activate like that, right? Also, since Stardust's effect doesn't activate when he's Summoned, I can activate bottomless, and my opponent can't negate, right?--Yugioh DED 15:22, June 18, 2010 (UTC)
