i like to use the following and reasons why:
ghost rider - power, and team work, plus abilities to strike more than 1 person
thor - raw power, plus flying abilities
wolverine - vicious, strong, and he can heal himself, a true fighter
deadpool - great special abilities, and teleporting ability saves a lot of time
im gonna get black panther, but havent unlocked yet, i also like to sue spiderman, silver surfer, human torch, and captain america as subs if im up for a challenge.
