Zeta on combat analysis will help immensely. General strategy is go for thrawn with the opening salvo, since he’s the only one stun will stick on. After that, remove all turn meter from traya with Luke. Then if fastila hasn’t gone yet remove her TM with Han. Goal is to prevent getting hit with either isolate or corrupted battle meditation. If you do that, you’ll win on the the counter-attacks. You should be able to keep traya slow enough that she never gets a turn, and then nuke fastila with 3PO.
