the MU waves are so weird, there is no real rhyme or reason to them, team waves would be a nice winkle they could slide in every once in a while,
they could include redos of main characters, some fringe characters and the main bad guys for that team

so a fantastic 4 wave would have the blue and black costumes, she-hulk in ff uni, some inhumans, the ff kids, mole man, molinoids, puppet master, super skrull, doombots, annihilus

also baddies waves could be cool, like a sinister syndicate wave, a masters of evil, brotherhood wave,

or alternate universe waves AOA, AOU, exiles, 2099, Squadron Supreme

or even an alien wave could have kree, shi`ar, brood, heralds of galactus
