Corvus or Havok, but if you can awaken nick fury, then I'd say go for him. Not sure if She hulk will serve you any good right now. Have you completed variant 3?
You don’t have a 6* worth ranking (unless that domino is? (Can’t see)6* are the long game, rank domino and Corvus if they are 5* I just had to decided between 6* domino or 2 maxed 5* I figure domino can wait a bit longer anyway, so I ranked Corvus and now deciding between domino or ghost 5* next for t5b use
