Oki, after about a week since I bought it myself, this is what I use:
Main team: X-23, Jill, Morrigan
CHEAP team (if I'm annoyed and cbb to play very fairly): Akuma, Dr. Doom, Sentinel
Secondary team (I don't use this too often however): X-23, Amaterasu, Morrigan
My gamertag is Gingerfoxy
I do have about 3 weeks left of the Xbox live
