Okay, here is a combo that has occurred to me recently.
Take a red squad vet, give her Comm Relay, and Cool hand with integrated mech. Get another X wing to bring Hyperwave Comm and give the Red pilot a perma evade token for a psuedo +1 health. Whenever you want, you can pop Cool hand for an evade that will do the same.
+ Integrated Astromech, we have a X wing that has Pseudo 9 ht points
But the madness does not end here, give them R3 Astromechs (which can generate evade tokens without actions) and you have something on par with a Falcon or even a Defender!
