Got a game tomorrow with a local chap who plays Rebels pretty well. I'm more than sure there will be at least a Wedge in there. Here are the two lists I put together. Still on the fence about which to run...

Boba Fett

Gunner

Stay on target

Marek Steele

Determination

Obsidian Ties x2

-or-

Echo

Adv cloak

Intel Agent

Predator

Shadow Phantoms x2

Adv cloak

if you go with th eshadows take stygium

Isn't Stay On Target redundant on him?

While I love an underdog, I don't think Maarek Steele is worth it at the moment. I think you would do better with maybe Dark Curse and another Tie Fighter.
