This is an excellent support for 4* Gamora at ranks 3-4. The bonus Blue AP on matches adds up very quickly, and the special tile improvement when firing a power is pretty handy when her two most-fired powers both generate special tiles themselves.

The boost to Blue match damage also ensures that she gets to use the rank 3 bonus even when paired with a stronger Blue user (say, Rocket and Groot).
