A list I've been proxying (bring on Wave 8!) and that's been proving very durable is the following:
Blue Squadron Pilot (22)
Tractor Beam (1)
Blue Squadron Pilot (22)
Tractor Beam (1)
Gold Squadron Pilot (18)
Twin Laser Turret (6)
R3-A2 (2)
BTL-A4 Y-Wing (0)
Warden Squadron Pilot (23)
Tactician (2)
Advanced SLAM (2)
Total: 99
The Sarlacc is composed of the B's (the tentacles) flanking the Y (the teeth). The Warden is the skiff, sailing about, herding people towards the kill zone and cutting off escape routes.
I'm not entirely convinced of the Tactician, I might switch him out for an Intelligence Agent and a Seismic Charge.
You don't use both Tractor Beams every turn of course, just when you would like to bring an opponent closer for feeding.
