You're right, no one has played wrap Ubers extensively, which is why I'm saying M2 requires a new look. On mechanics alone, he's beatable assuming the M2 just sits there and tries to use his uberness to win. One tourney won't be enough to demonstrate anything, especially if it's best of 1 single elimination. It's not as if I said M2 to beat or anything, I just think it's more manageable than it is without wrap. As for whether it's Uber or not, I find the Ubers tier in general pretty pointless in a gen where you still have to use four OUs anyway.
