I rarely if ever make Smash suggestions as jokes, everything I vouch for, even if it's a fundamentally comedic idea like the Sega logo or something, there's always some underlying logic or cool factor... that being said, if I was put in charge of a Real Actual Smash game, I would pull a "grimdark Epic Mickey" and just make a fake roster filled with the most stupid Nintendo references that would never ever work no matter how creative you are just to test what Nintendo allows - Who's ready to fight as "Zelda key piece from Nintendo Cereal System" or "Torn out page from Nintendo Power promoting an aborted contest to appear in the cancelled Mask 2"?
