As a Poison-type, Muk fills a straightforward role. Only weak to Ground and Psychic. Known as the Sludge Pokémon. Known as the Sludge Pokemon. The stat spread favors raw physical power.
Muk's built to absorb hits, not race for knockouts. Special bulk with HP doing the heavy lifting. And the medium-fast 1M XP curve means it won't take forever to bring up, worth 2 HP and Attack EVs.
The garbage it eats causes continuous chemical changes in its body, which produce its exceedingly vivid coloration.
While it’s unexpectedly quiet and friendly, if it’s not fed any trash for a while, it will smash its Trainer’s furnishings and eat up the fragments.

Step 2Muk ✓
Muk works as a tank with 500 BST behind it. C-Tier on our list — a situational pick that fills a niche. That 105 base HP does the heavy lifting.
Stench has a 10% chance of making target Pokémon flinch with each hit — that's the one you want on Muk. Poison Touch is the hidden ability. Niche, but it has its uses. Sticky Hold works too if your team needs something different.
Muk is a physical attacker with base 105 Attack. Tanky enough to absorb a few hits, too. But the speed tells the real story — base 50 Speed is low. Priority moves or Trick Room are the way to go. Fits the tank role.
