Ok here are the rules ...I hope you know most of these.
Can't normal summon a monster but once per turn unless you use a card effect that says otherwise. Such as Double Summon.
Can't activate quick play spell cards the turn they're set....
Can't activate traps the turn you set em either.
If a monster says "cannot be special summoned except by" then it cant be special summoned except by that effect.
If a monster says it can't be special summoned.....it can't be special summoned.
You cannot bottomless Gorz if hes SS from his own effect.
If a card doesn't say "Target" then it doesn't target.
You cannot and I repeat you cannot negate with Mystical Space Typhoon.
Priority. Priority, Priority. If you summon a monster for the majority of them you CAN activate its eff when its bottomless trap holed. Synch into Black Rose? She gets Bottomlessd? You can still nuke. Attack with Galaxy-Eyes opponent D.Prisons? You can use his eff. ...well ok bad example. But you get the point. And please don't veiler a Rescue Rabbit.....
