Ghost crew op

So what's up with the ghost crew meta? For a majority of my squad arena battles it's Hera as the leader, the 2 tanks, and usually Ezra and Rex, but lo and behold my pain as I find one of these teams in galactic battles early on, I understand that their team Dynamic is "amazing" and the only potential counter I've found so far is getting hando far enough into the match that he maxes out his ransom and slowly attempts to widle them down, my problem is that this battle is still going on because I know if hando can't take them down the rest of my people can't lay a finger on them since the rest of my top team members for this battle died removing Hera. 

Just to put it into perspective Hera died 3 hours ago, send help 😢
