Hariyama

Hariyama is a victim of circumstances, and rightfully so. It's a tough world for Hariyama in OU when there is Machamp lurking about with STAB No Guard Dynamic Punch at its disposal. Hariyama may seem outclassed in every possible way, but there are a few useful niches that Hariyama can claim and therefore edge out his four-armed rival in some way. Most of these niches stem from useful movepool options such as Fake Out, which can give Hariyama the free turn necessary to activate a status Orb and break Focus Sashes. Generally speaking, in OU you will want to use Machamp, but you may occasionally find Hariyama's features more useful for your team.
