Mods for Commander skywalker?

I've gone crit damage crit chance.

Im thinking speed/potency
Speed arrow
potency cross

Secondaries: offense, speed, and potency

Run him with a super fast r2, im not sure about the rest. Can throw in chaze, gk, nihilus, thrawn, rex, or old ben. Im just thinking of speed. Possibly raid han. Im mainly thinking of using him in a mixed team, not just rebels.

A basic rebels team could be luke lead, r2, raid han, and chaze. All of them super fast ahould keep you in the top 50 of arena.
