>>19914536did you mean using it against Psychic/Ghosts? If yes, don't worry, I always use that to take them down.
Or did you mean my opponents knocking off the vest? If so, Lum Berry could also be knocked off. Additionally, I doubt that many would dare use it against a powerful Fighting type that resists Dark, no? Machamp ma not be bulky, but he's not frail either. If opponents are knocking off his AV he gets one free pass to potentially OHKO an opponent. Then you can maybe pull withdraw him.
