This is the squad I've been using lately
Chewbacca (15)
Diala Passil (7)
Jyn Odan (5)
Rebel Saboteur (5)
Rebel Satobeur (5)
Gideon Argus (3)
Total: 40
I have only played this squad a couple times so far but I have found it very solid, with a strong combination of firepower, speed, and control (via stun).
I have however, been unsure on the best command cards, this is what Ive got at the moment.
Debts Repaid (Chewbacca - 3)
Take it Down (Gideon - 3)
One in a Million (Jyn - 2)
Sarlacc Sweep (Diala - 2)
