Malevolence should be you best bet, Negotiator next, kindy tricky the mirror matches, or Ackbar (with a lot of effort)
Chimera and Executrix could do the trick with geos and maybe some cleanse of Gar Saxon / Plo Koon to pull away those dazes
Really people, start investing on ships please, by saying there's 2 fleets in defense, I assume you're on Div 2 or 1, you should be able to counter them!
I know you may not like them, but they're part of GAC, and if you want some juicy W's, you will need to invest on them
I'm 20k GP away from Div 2 and alredy have 4 viable fleets, and 2 leftover fleets (finalizer and resistance)
I always get to Kyber league, and mostly I can assure you 80% of my wins are because the enemy couldn't beat my fleet lol
