Just saying that this set works absolute wonders in 1v1. Whilst it doesn't beat every Pokemon (nothing does), it beats a whole lot of the top Pokemon a lot of the time. The good thing is, Medicham is not common
at all in 1v1, so the opponent often doesn't know what to expect.
Fake Out is the crux of the set, breaking Focus Sashes (if the opponent doesn't have Protect) and dealing a crapload of damage due to Medicham's 480 Attack. Magic Coat reflects Darkrai's Dark Void right back at them, putting them to Sleep if they hold a Sash and, if they hold Lum Berry, that's where the mindgames commence; I've managed to win against Darkrai a lot more than they win against me. HJK is obscenely powerful, killing a lot after a Fake Out. Ice Punch is there for Skymin, but it beats me 60% of the time, due to Air Slash's flinch rate. Bullet Punch should be used after Darkrai is banned, due to Protect 'Mons, and Ice Punch should be replaced with Psycho Cut for Ghosts.
