I need a good fire poke for my team. I'm not sure what one, or what role. (sorry if that isn't help) I was thinking about a Flareon as a physical sweeper, or a Houndoom as a Special Sweeper.

Flareon (+Atk. -Spd.) [252 Atk. 252 Spd. 6 HP]
Overheat<>Shadow Ball<>Return<>Quick Attack/Wish

Houndoom (+Spd. - Atk.) [252 Spd. 252 Sp. Atk. 6 HP]
Crunch<>Fire Blast<>Pursuit<>Counter

These are just a couple of my thoughts. These are not the only 2 pokes that my decision is limited to, and I've already got a Fighting so Blaziken is probably out. Any other help would be appreciated.
