Houndoom

Houndoom is UU's most powerful Nasty Plot sweeper, and often the most deadly as well. Its great dual STAB and auspicious stat distribution allow Houndoom to cut through unprepared or weakened teams like a hot knife through butter. Although its function is fairly one-dimensional, Houndoom's methods can vary greatly between sets, and this versatility is what makes Houndoom such a dangerous threat. Each of its sets has a different trick up its sleeve, and making assumptions about which set you're facing can often lead to your demise. Unfortunately, Houndoom's Stealth Rock weakness and subpar defensive stats mean it cannot take hits nearly as well as it gives them out.
