CLS, Han, R2, GK and?

Double Kenobi. A zzOB under CLS is a pita to kill and the tm gains make it even better.

Thrawn is a great addition to this team to indeed fracture Sion or Palp. I recommend fracture on palp so his stun and shock dont slow you down and then kill Sion first

Another option if you have rex is to run a rex lead with cls raid Han gk thrawn. Then you can put tenacity up after Sion dispel so stuns etc don't stick. Makes EP teams a lot easier to beat

@WitnessedJarl Thanks for the reply. Definitely haven't worked much on Rex but its a good idea. Ive often been able to instantly kill EP with han and CLS so a fracture on sion to follow would be an easy win.

Would this also work against the 2 whales with JTR and bb8?

It should. Do note that a lot also comes down to mods. Versus rjt teams you want to use Han to shoot bb8 first. you want to put buff immunity on gk if they run him so he doesn't get his taunt and when you get the chance fracture Rey or else bb8.

Even Palp is a good addition.Most of the guys will use Leia for her stealth.
