Agility Arcanine
EVs: 252atk 252speed 4def/sp.def
Nature: Adamant
Item: Life Orb
Ability: Flash Fire/Intimidate
Move 1: Flare Blitz
Move 2: Agility
Move 3: Crunch
Move 4: Thunderfang/Dig
Intimidate is great but getting the Flash Fire boost is even better on a sweeper like this. Everything is self explanatory except for the last move. Thunderfang works for Gyarados, but it is too weak for almost all other enemies (compared to Flare Blitz). Dig just makes it so this set isn't completely walled by Heatran, and it saves some HP if you want to attack some random Poison type. Good for late game when counters are gone.
