Mawile

Mawile has a great typing that allows it to check popular Normal- and Grass-types such as Stoutland, Roselia, and Cacturne. Great offensive prowess with Sheer Force-boosted attacks further augmented by Life Orb and the option of going mixed make it a great wallbreaker capable of destroying common defensive cores. Despite mainly being a wallbreaker, it can also sweep offensive teams with Swords Dance-boosted Sucker Punches if given a setup opportunity. Mawile can also pull off a defensive set to check common physical attackers and provide Stealth Rock, though unfortunately, bad natural bulk prevents Mawile from making full use of its great typing because most specially offensive Pokemon such as Mr. Mime will still 2HKO it. It is also overreliant on Sucker Punch against faster Pokemon, which can be exploited with moves such as Substitute and Will-O-Wisp and also makes it not very hard to revenge kill by faster Pokemon that can take one hit.
