Forum:Cold Wave vs Diamond dude

If I hit Cold Wave with diamond dude, can I activate it during main phase 2? And also, Can I activate Cold wave, then use a spell effect from a spell card sent to the grave by diamond dude last turn? Last one. Can I d.d. Crow the spell card sent to the grave by diamond dude and stop it's activation? Can I chain to it? War Pigg 01:50, 24 July 2009 (UTC)
