Moldy Crow is possibly the best upgrade of 2.0, so any list that can run a Crow should consider doing so. Here is a rebel 4 ship list based around Biggs and Rex that aims to have a Moldy Crow and Wedge late game:

Biggs Darklighter (48)
Servomotor S-Foils (0)

Captain Rex (32)

Kyle Katarn (38)
Selfless (3)
Perceptive Copilot (10)
Moldy Crow (12)

Wedge Antilles (52)
Servomotor S-Foils (0)

Total: 195

I think I like the basic principle here, though Rex may be too expensive. Wedge gets to hammer with double modded shots while Biggs/Rex protect him. Kyle is useful through the entire game, both as support and as durable gunship. Points of tweaking I see:

• Roark may be useful to boost Rex, but loses mods for Wedge and becomes a lot less useful when Rex is inevitably dead
• Initiative is all over the place - not much you can do here
• Selfless may be a bad upgrade here, or maybe Wedge should have it, too, if it is good
• Either way, Wedge could use some gear possibly, though the bid also is a good thing to have for him

Rebels' problem in general at the moment, IMO.

I think a talent on Wedge is way more valuable than Selfless on Kyle.

I agree you probably want some points held back for a bid, but Selfless kinda means you need to weld Kyle to either Wedge or Biggs, depending on how you're expecting to spread fire around and I'm not sure that's best for him.

Kyle's ability goes out to range 3, and I think that's where he wants to be flying really. At a distance, engaging indirectly with the turret and occasionally turning in for a primary.

Wedge's talent is a tricky one. It depends a lot on what you want to do with him. I think in this sort of list, he probably wants to be at range 3 a lot of the time, so I'm hesitant to suggest a bullseye ability. Trick Shot is solid. Elusive might be okay too, as he needs a bit of defensive help. Probably too expensive though.

I actually wonder if maybe the best use of those 3 Selfless point is in fact Engine Upgrade on Kyle. Boost feels like a pretty powerful action at the moment, and not limiting your dial immediately after using it might be wise.

Rest of the list looks solid, I think. I know of at least one school of thought that suggests dropping Wedge down to Thane would let you take Attack Shuttle Sabine instead of Rex, and she looks like a very solid filler.
