Thank you all for taking the time to give me your answers! I really do appreciate it. I've reached the maxed out 4* wall, and I'm having trouble advancing any further.
Doc, Rouge, Hawkeye, Bishop (I know people are mixed about him but I personally like him), and If you can awaken him Dr Voodoo first (if not wait for duped)

Also Hawkeye & Elektra
If you awake your Voodoo its one of the best choices by far
I would focus more on those before the Champ
