Arena team tips

Willkimm98

I currently run phasma (L) 7*, ig86 7*, lumi 7*, poggle 6*, and poe 5*. I am f2p and sometimes maybe 40% of the time finish top 10 with 4 top 2 finishes (rank 1 twice). Looking at my other characters, what would you say a better team would be? I am not on a whale server because i never see leia or any chromium only characters. I am thinking about switching lumi out for someone, but dont know who. Should i make any changes? If so, then who should i put in?

Wish my server was whale free I'm doing good to stay in the high 200 or low 300 rank.
