Cap/Skrull/Task seems like it would be an okay team. Cap is pretty easy to combo with and hits HARD, and using Task's assist and backflip should help you get in. If Cap and Skrull both die, you get Taskmaster at anchor, who does stupid damage in XF3 and has great projectiles. I don't know anything about Skrull, and I always have problems fighting the good ones I come across online.
