Mienshao

Mienshao's base 125 Attack and 105 Speed might make it appear to be yet another run-of-the-mill Fighting-type physical attacker, but it sports a usable base 95 Special Attack stat that allows it to get past would-be counters such as Gliscor with Hidden Power Ice. That's not all: access to a powerful STAB High Jump Kick, a fantastic ability in Regenerator, and U-turn make Mienshao a potent hit-and-run attacker that can tear gaping holes in the opponent's team. It even receives Reckless from the Dream World, jacking up the power of High Jump Kick to obscene levels. However, the presence of Shadow Tag Chandelure means that Mienshao must exercise extreme caution when using High Jump Kick, particularly on a Choice set. Mienshao's poor defensive stats also allow most neutral STAB moves to deal heavy damage if not OHKO. Still, don't let that deter you from using Mienshao; with the proper support, it can run away with games easily.
