A rebel list that I made with one core that does alright is Corvette B with Dodanna and Dodanna's Pride, Neb B Refit with Redemption, 2x X-Wing and Luke. Obj cards are Precision strike, Fleet Ambush and Intel Sweep.
Intel Sweep is a pretty obvious one, just fly around grab a couple objectives and game is over. Precision Strike is nice with Dodanna and Luke, slow crawl it until you can use the squadron ability, again no reason to blow up anything, just land a few hits and get the objective points in round 5 and 6. Finally Fleet Ambush. Puts the Star Destroyer in the middle of the map, which opens up the flank right away. It takes a lot of movement away from the Vic.
