I thought of this while looking through Counter users for my new PBR team (ZeroBPWin), I was suprised to see Houndoom had no Lead set so I made one up.
This set is meant to deal with a majority of Leads stoping or stunting their success.
Froslass was one of original threats I considered when making this up; though you can't outspeed you can Taunt killing 2 birds with 1 stone, Preventing Froslass from laying down another layer of spikes or Destiny Bonding allowing you to OHKO with Sucker Punch or Overheat easily.
Crobat, with a Hasty nature and 0 Defense IVs, Brave bat Crobat will OHKO 100% of the time taking 120% bare minimun, and Counter back KOing the little bat, same applies to Staraptor leads.
Ambipom though Trickier is also beat, Jolly Fake Out (Life Orb+Technician) won't KO Houndoom which allows him to Sucker Punch twice 2HKOing the little monkey, you can't Counter since Fake Out flinches. It can Taunt + Overheat or Taunt + Counter Steelix; Taunt + Sucker Punch(2HKO) Rotom or Overheat if you're weary of Trick, Taunt + Sucker Punch a U-Turing Uxie.
More info, You want to run 0 in def IVs it will allow you to Counter a majority of leads I just listed some of the most prominent, while Taunt can prevent you opponent's Stealth Rocks/Spikes/Toxic Spikes from being laid early in the game. Priority is always great, which is where Sucker Punch comes in. EVs put Houndoom at 279 Atk 2HKO a wide array of threats or OHKO some, while pumping the other half into Speed, and the remainder in SpA to boost Overheat's power.
Forgot to mention abilities, Early Bird is the preffered ability, though if you think you can get Houndoom in later, on a predicted Flamethrower/ Fire Blast / Overheat / Will-o-Wisp, go for Flash Fire.
You get the point. If you want calculations I can provide them. This was partly inspired by lead Arcanine, from Legacy Rider.
I'll re-edit the Speed EVs later if I recall he only needs 216.
