The only good thing about Emboar is that his Reckless Head Smash is stronger than Tyranitar's Stone Edge. A Choice Band Reckless set hits harder than just about anything else (it compares to Specs Porygon Z).

Flare Blitz / (fighting move) / Head Smash / (electric Take Down). Not much can switch in on this. Even Physical Skarmory is 2HKOed by pretty much any move. Sure it won't last long but with a Jolly nature and 252 speed EVs you can at least outrun Tyranitar, Scizor and Nattorei.

Play him in a tier with team preview and predict well and it could very well wipe out several Pokemon before going down.
