So when {Clever Impersonator} enters the battlefield as a copy of {Master of Waves} do I get more 0/1 creature tokens or just +1/+1 to the existing tokens? If I get more elemental tokens I'm guessing I count the {Clever Impersonator} as one blue mana symbol because its a copy of {Master of Waves}?
You do get more tokens, and the impersonater will count for one blue mana symbol.
Thanks.
