Two wookie commandos are probably better than breach specialists here. You need some offense.

What a pain the wrong list posted.......but yeah needs more offense, I want two of these to work but probably not gonna happen

Wullffwaroo is the weak link here - he doesn't actually serve any purpose other than as a damage shield so:

Lowhhrick (28)
Auzituck Gunship (28), A Score to Settle (0), "Chopper" (0)

Biggs Darklighter (29)
X-Wing (25), R2-D2 (4)

Captain Rex (14)

Heff Tobber (29)
U-Wing (24), Collision Detector (0), Jyn Erso (2), Jan Ors (2), Pivot Wing (0), Tactical Jammer (1)

Totalling 100 points.

If you fly it right (Heff in fron of Biggs, everyone at R1 of Biggs) you get an AGI 3 damage tank (because of tactical jammer), that has probably 3 focus and 1 evade token (that cannot be blocked due to Heff's ability), plus a extra evade from the spent reinforce token, plus -1 attack die on the big hitting enemy ship. Plus shield regen. This is about as tough as you can make Biggs. Of course if Biggs dies then you've lost the game, but that's okay.
