Hello. I have thought of an interesting moveset for an Arcanine.
Nature:: Impish
EV's: 252 HP/252 Atk
Nature: Intimidate
Held Item: Life Orb/Leftovers
Flare Blitz
ExtremeSpeed
Morning Sun
Protect/Toxic
First, the EV's. 252 HP makes it survive most attacks with the assist of Intimidate for physical sweepers.
Second, the last slot. Protect is used for Double Battles and some support by it's partner. Meganium I believe is th best partner to boost up Sunny Day and let Arcanine do the damage. Toxic is for Single Battles to wear down stallers that don't have Rest.
So, what do you think? Any good in some circumstances?
