It's not official, but Magneto_Acolyte looks to be the winner...Osok or Brandon would have to win out in order to even have a chance, and Magneto would have to finish in last.
It is improbable this will happen given the fact there are still over 20 games to play for Osok and brandon. I won't declare the winner until it is mathematically plausible, but the odds are definitely in Magneto's favor that this tournament is over...
