Needing help to improve my marvel

ive been playing for a while and i know combos quite fancy combos and some setups i still fell as though i dont understand some of the game. i run a real front heavy nova spencer doom team but what i really want is someone to play with that could possibly teach me some things and give insight to how to better my team or what would probably be basic knowledge as in when can i do this if they push block here or how to punish this or just main strategies i might not know about. i play on xbl.
