C3PO is a big miss from that team (Arena speaking)
It’s worth farming Ewoks early as they are pretty solid secondary team with zeta Chirpa and Logray + Wicket. Also Wicket = extra zeta mats from their event. Also the teams is often underestimated in GA(C) & TWars.
Saying that.....options in the meantime =
Thrawn —> Universal plug and play with Fracture and protection recovery, TM swap etc
Old Ben —> Mind Tricks (with high potency = win), Taunt & benefits from R2 and CLS. Only zeta his taunt, the other zeta is a waste.
Bistan —> “wild card” choice, needs to be fast as possible and low enough health that he gets Chewies Guard. The idea is that you are going to use Frenzy early and then take a bunch of extra turns with Chewies Guard assisting = massive early damage.
