Good luck with that~ ;D
Eh, nothing really to "configure" with the physical set lol:
Arcanine @ Choice Band / Leftovers / Life Orb
Ability: Intimidate / Flash Fire
Nature: Adamant / Jolly / Naughty
EVs: 4 HP / 252 Atk / 252 Spe
- Flare Blitz
- ExtremeSpeed
- Thunder Fang
- Iron Head (Platinum tutor move) / Overheat
Yeah, basic, ExtremeSpeed is what makes Arcanine very invaluable in UU. 8D Thunder Fang for Moltres, and Water-types, but not Quagsire and such. Iron Head for Rock-types, but since it provied awful coverage other than hitting Rock-types, Overheat is worth a slot. Even with no SpA EVs and Adamant / Jolly Nature, it still dents physical walls, but you can opt for Naughy Nature, and add the 4 EVs to SpA.
