Since it destroys your swarm tiles, it should be cheaper so you can actually cycle through multiple times per match. I feel like that would make wasp much more fun to play. It should be cheap, like 7AP or so.
Call the swarm, is just bad over all. The match damage you do, over a couple or few normal match moves, is basically equal to the damage Call the Swarm does. Granted, this is depending on the amount of swarm tiles on the board. All of her abilities are so bad, there really is no reason to want to cast them again, once you have enough swarm tiles on the board.
Crazy. You have enough time to use call the swarm in a match?!?
