Tank suggestions for arena

Bill0207

I'm currently running palpatine, vader, nihlus, thrawn and shoretrooper. I was running gk as my tank but decided against it due to him giving bonus speed to opposing vader. I've been thinking about sion because of his synergy with nihlus but mines only 3* until he becomes farmable. I'm open to any suggestions as well https://swgoh.gg/u/bill0207/

If I'm not mistaken even at 3* gear 11 especially with his zeta Sion is very viable

Sion at 3 star is still great, if you gear him up. I'm keeping mine at gear 9 and he's still good. Have to save pieces for BOSSK

I strongly recommand Sion. He is fantasic. With zeta, he is the most cruel tank on the dark side.
