Did it after a lot of tries with :
7* poe lvl 80 gear 8
7* Rey llvll 80 gear 10
6* Finn lvl 74 gear 8
7* resistance pilot lvl 72 gear 8
5* ressistance ttrooper lvl 72 gear 8
You need a lot of luck in the last part against Rey. Basically she needs to use her special on your Rey having foresight and after you need to stun her with Finn. Obviously, this to 3* it otherwise much easier.
I did it with Rey, Poe(as lead), and RP at 7*. Finn and RT at 5*. All gear 8. Put my mods from my arena team on them. All lvl 82. All ability ar 7 except for poe's taunt and Finns lead. Speed helps a lot so you go first in the first round. Luck helps too Rey only used her basic on me the very first time I tried it.
Even with a half decent team it all comes down to is rey going to attack Poe if she hits any of the weaker ones they are one shotted took me about a week to do it with 7 star g10 80 rey g9 80 Poe g7 72 piolt and trooper and 5 star g8 72 fin all modded health and defense
