My main team is Akuma/Skrull/X-23. If Iron Fist is decent, I'll probably replace X-23 with him.
My other two teams right now are Cap/Ryu/Wolvie and Morrigan/Trish/Storm. Neither of those will change, but I'll probably start playing with two new teams now:
Chun/Viper/X-23 (I always wanted X-23 for this team anyway, but I liked her too much in my main team.) Strider/Vergil/Zero (I'll probably suck with this team, but I'll be damned if I won't still play the hell out of them.)
