Arena team against JTR (no Thrawn)

Hi guys!

I can't take JTR and looks like my all shard can hahahahaha What I gonna do? I have no good Thrawn and actually I use GK Zarris CLS R2D2 and DN.

What is the best team that I can put in arena? (We have just one NS team - thanks God!)

Is Rex lead a good option against JTR?
