[Overview]
If your team really, really needs Chimecho out of the way, then your long search for a solution is over. Houndour is typically immune to Chimecho's offensive moves, and with STAB Pursuit and Crunch Houndour can easily take it out, even if it tries to switch out or has boosted with Calm Mind. Houndour is also decently strong, meaning it's not totally useless outside of this specific role. Don't get your hopes too high though, as Houndour's frailty is extreme, meaning it's easily OHKOed by almost everything faster than it or by anything that can withstand one of its STAB moves. Diglett is going to be a better trapper for your team almost 99% of the time, but if your team absolutely needs Chimecho crippled or out of the game then Houndour may be the solution you're looking for.

[SET COMMENTS]
- Pursuit and Crunch ensure that Chimecho will be severely maimed and deal a decent amount to most of the Pokemon slower than it
- Fire Blast can get a Flash Fire boost and takes out Mawile and Grass-types
- Will-O-Wisp allows Houndour to cripple slower tanks like Relicanth and hard switches like Hitmonchan
- Taunt protects Houndour from status from Chimecho and ensures it can't stay in and keep boosting with Calm Mind
[ADDITIONAL SET COMMENTS]
- Timid lets Houndour outspeed as much as possible as it's pretty much KOed by anything faster than it
- Overheat an option over Fire Blast for more power
- BlackGlasses or Charcoal an option over Leftovers since Houndour isn't going to eat more than an attack or two anyway
- Sunny Day and Solar Beam an option as well to support Bellossom and Tangela
- Needs a teammate that appreciates Chimecho crippled or out. Agility Hitmonchan, Choice Band Golbat, Dragon Dance Pupitar examples
[Other Options]
- Sub + Reversal
- Thief and Toxic
- Hidden Power Grass or Water
[Checks and Counters]
- Anything faster than it not named Haunter
