Here is a post Wave 4/Rebel Aces squad. I think it could be absolutely devestating against XXBB and Swarm lists (which is the current meta)

Airen Cracken - Cluster Missiles, Swarm Tactics (25)

Lt Blount - Assault Missiles (22)

Bandit - Assault Missiles (17)

Jake Farrell - Assault Missiles, Push the Limit (32)

Comes to 96 points - thoughts on the last 4 [including upgrading Jake to Tycho maybe?]
