Arena help!!

Gingermann

Hi guys
I'm kinda new to this game, and has played it about 1.5 month.
I have been farming the Phoenix squad since i started playing swgoh so I could get Thrawn. Now that I have him, im starting to wonder what Arena team I should run, so I was hoping that some of you more experienced players could help me find a good arena team that i should start farming with Thrawn in i

This is my roster: https://swgoh.gg/p/117539649/characters/

Empire command - Palpatine, Vader, Thrawn, Tarkin, Tie Pilot is the usual progression.

Keep farming your phoenix to 7* to promote your Thrawn to 7*. Then switch to empire. Another common route is to proceed to NS in arena, but NS don't unlock any new characters like Empire do.
