Thrawn squads without GK or Krennic?

So, I went all in and managed to 7 star Thrawn at the end of the Phoenix event. Thanks double drops and fleet shop luck, and thanks banked arena and cantina currency!

And now I've gotten him to G11, because damn if he isn't a favorite. But... I'm just not sure what sort of squad to build around him, given that most strong options require GK or Krennic, of which I've neither. (Well, I have Krennic at 5 star G7... I'm working on it. Slowly.)

What I do have, is my Zader led arena team, (Zader/TFP/Shoretrooper/Boba/DN) at 7 star/G11, along with a very beefy Palpatine, Deathtrooper a lucky Rancor or two out from G10 and then 11, and a 7 star G11 Tarkin.

I'm just not sure what to build around Thrawn to stop the bleeding as my Zader arena team just isn't working the way it used to. I can still usually get to number one at payout - but it often costs me 50 crystals to run 6 attempts at the Wiggs/Chaze/R2 or Rex/Chaze/X/Y comp at the top, a battle which requires I get about a half dozen sequential RNG checks right to win before Tenacity Up totally neuters me.

So what should I build around Thrawn?
