Naughty Nature (+Atk, -SDef)
- Sucker Punch
- Spite
- Reversal
- Overheat
Houndoom has terrible defense, and as a lead, you want to survive as long as possible to do serious damage before going down. Focus Sash easily takes care of this problem. It also helps to boost Reversal drastically, seeing its based on how little your HP is. Overheat is there as an altnerative in case Physical Walls. Sucker Punch will also help to rid the enemy of the little HP they are left with in case Reversal didn't take them out. Spite is mostly therefor filler, but can help to annoy stuff like Dugtrio's Sucker Punch and Meinshao's (rare) Detect.
