Need help putting a team together

Hi everyone,

Fairly new player here, my problem is i dont know which characters go well with each other. Recently i found been running SW (champ) and PHX 270 with either IF(champ)/Blade/Magneto (classic)/OML, way too often and im getting bored of them. I have 53 man roster. I have been told Red hulk is a beast i have him at 232 lvl 110 but have no idea who to pair him with. Can anyone suggest a few teams that i might be able to put together?

Thanks in advance

Tipps and Guids are full of rainbow/synergy teams.
