There have been a lot of physically offensive movesets, but with base 119 defense, why not make him a physical wall? He counters Talonflame very well and has worked effectively on battle spot.

With the Strong Jaw boost, I feel that Poison Fang outclasses Toxic, despite the 40% lower poison chance (90% accuracy to 50% chance).
Dragon Tail phases out any special attackers that may want to switch in, while also dishing out STAB damage.
Your Rock move of choice gives further coverage and STAB. I prefer these to Head Smash whilst using him as a physical wall because damaging yourself won't help your cause.
Stealth Rock is always nice if you can set it up, especially before the likes of Talonflame and Volcarona come into the battle, or any sash user for that matter.
Lacks reliable recovery, but functions well at what he does.
This is my first post and any constructive criticism would be much appreciated.
