Dunno that Missingno would have done better in a day match. There are more votes in a day match so rallies matter less. And Missingno couldn't replicated the Power Hour in a day match because even though a day match gets much more votes overall, the first hour gets much less, and there isn't such a big surge for Nintendo/Pokemon/Jokes and against FFVII in it either.
Interestingly enough, Bowser/Charizard got 6000 more votes than Mario/Charizard. That suggests Charizard did not get bandwagoned between those matches, though perhaps he was already getting extra support in the Bowser match. Not conclusive either way, but Mario only being at 58% on Bowser as the Charizard matches is sort of strange as he's always been above that.
