Durant

With an exceptional Speed tier, Durant is able to outrun key threats such as Mienshao and Cobalion while also Speed tying with Heliolisk. Having access to Hustle, Durant's already solid Attack is buffed massively, giving it grand wallbreaking potential. Durant also has access to Hone Claws, which not only raises its already high Attack, but raises the accuracy of its moves, removing the appalling downside of Hustle. This is backed up with its fantastic typing not only offensively but also defensively, as Durant's typing has only one weakness, one immunity, and many resistances. However, Durant's decent physical bulk and typing is let down by a very poor HP stat and pitiful special bulk, meaning that even resisted hits will do a hefty chunk to it. Durant's typing also leaves it horribly weak to Fire-type attacks, which are quite common on Pokemon such as Entei and Infernape. Hustle also means that the accuracy of all of Durant's attacks will be lowered to 80% at best without a Hone Claws boost, which means any one of its attacks could miss at a crucial moment.
