Also see here for the ruling on the card reverberate


8/15/2010   When {Reverberate} resolves, it creates a copy of a spell. You control the copy. That copy is created on the stack, so it's not "cast." Abilities that trigger when a player casts a spell won't trigger. The copy will then resolve like a normal spell, after players get a chance to cast spells and activate abilities.
