certain Cryptozoic deck builders have the same back for integreation. The LotR deck builders all can mix.DC can mix with Street Fighter or even the new Naruto deck builder as they have the same backs to the cards.
I would not just mix it all but choose which parts to add to make sure all are viable together.
With mixing the Street Fighter and DC you choose which end condition to play with. Either the Street Fighter Victory condition or the DC Super Villains but do not use both for end game.
