Although Intimidate is a nice tool, Arcanine is weak to Stealth Rock, which limits a lot of what it can take. Either way, Bulky Heatran can do the job better. Arcanine isn't exactly built to be a tank. D:
Besides, Smogon's set requires HP Ground, and I pretty much irk at HP breeding..
The standard Adamant/Jolly Arcanine is fine.
