I'm not saying its gonna happen. But it would work thematically as a villain who would help fight Terminus.
I'd like a Proletariot hero deck but I just think his villain deck just makes it a bit rough to implement. If he goes by a different name that resolves issues I see with it
I'd personnally see Baron Blade team up with the good side, at least temporally, to prevent the end of the world, ala Lex Luthor...? To give a bit of credibility to this guess, I'd ask you to take out the Ruins of Atlantis deck and look for "The Pillars of Hercules" card. We recognize at least Legacy and Bunker and... Baron Blade in his power armor? They don't seem to be fighting in this particular scene, right? Also, maybe the Ruins of Atlantis holds more secrets than we might think?
He could easily be called Everyman wich is his official translation of his russian superhero name. Of course, then why not call him that in tactics?
