For the sake of decent synergy, Rescue can actually be useful in the event using Polaris and BrB where possible.

Rescue must be set at 3/5/5 (blue will mostly be for Polaris). Normally yellow is trash. But as it happens, once Polaris starts doing her magic, yellow will turn ALL friendly tiles to defence one’s. At that point you are basically immortal, especially in regular nodes where brb will generate ap nonstop, and also aids do or die.

Ideally have carol’s communicator support attached to Rescue, she will need it as the main flaw is she tanks everything and the first turns might get some punishment. Once the tile bonanza gets going she will be topped back in no time.
