Machamp is simply a menace to a lot of teams. I ran a team with TTar, Keldeo, Terrakion, Celebi, Lando-I, and Foretress and basically I was insanely Machamp weak.
Machamp's lead set was stupidly dominant in DPP partially because literally nothing could OHKO it-- pokes like ZAM or Azelf would NEED LO to do it-- something they couldn't use because they needed sash to be effective as leads. Honestly, if there was no team preview I think champ would still be OU. That lead set can fuck an unprepared team even with preview.
