Probably best with Biggs, although I really liked a Jyn Jan U wing with Cassian driving with expertise. Or throw Rey in, Jyn was fun, but only triggered about twice.
ARC-170 and ...?
I had a lot of fun last night at my local club flying this list.
Wes Janson
Juke
R3 Astromech
Integrated Astromech
Luke Skywalker
Juke
R3 Astromech
Integrated Astromech
Shara Bey
Swarm Leader
R2 Astromech
Weapons Engineer
Alliance Overhaul
Not the most competitive list out there but it has a lot of jank in it. Spending an eyeball that you can't do much with anyways into an evade which you can then use to juke is fun. And if the xwings don't have to spend those evades Shara turns them into extra red dice when she attacks. Also it turns out x-wings can be pretty tanky with a focus and evade token.
R3? Do you even X-wing?
I know right how dare I go against the forum group think and play stuff that's not the top end competative stuff on casual game night.
Oddly enough though it was working pretty solid.
Nora + Dutch + Biggs. Nora needs target lock. Dutch fix that. Dutch needs protection. Biggs fix thst.
Non standard suggestions:
Norra, Poe and Rex Tie or A-Wing
Also possibility Norra and Ghost for max damage build
Norra and Dash also seems to work, even if it works better with Miranda imho
