I have quite a few Rebels to hand,what should I field do you think?

6x Z-95's; 3x X-Wings; 2x Y-Wings; HWK-290; YT-1300; YT-2400; YV-929

Z swarm is good. Luke Biggs Wedge is classic.

Is there an alternative to the overcosted x-wing trio?

Corran Horn (42) E-Wing (35), R2-D2 (4), Fire-Control System (2), Veteran Instincts (1)

Bandit Squadron Pilot (12) x 3

Lieutenant Blount (22) Z-95 Headhunter (17), Assault Missiles (5)

Not sure, but how about this? Corran does his thing, and Blount is your swarm/interceptor insurance... No EU for Corran tho :/

Sorry,but I don't have an E-Wing,as it's even more expensive than the x-wing and I don't like the model.

Here's an interesting one: 99 points

Cracken

Dutch - R5K6 and Blaster Turret

Dreis - R3A2

Roark - Blaster Turret

Get extra abilities out of everyone, stress enemies, quite a bit of red dice each round.
