Forum:Stardust and coldwave Rulings...

Mmmmmm......I was just wandering if I can activate other spells or traps before I can activate Cold Wave itself? and I was just puzzled about ATEMVEGETA's answer when he said that Stardust Dragon cannot negate Snipe Hunter's effect because he said it is not sure whether that card it will be destroyed but what about after it is sure,cant I still negate it with stardust??...please I need verification,answers...except coming from ATEMVEGETA(no offense)
