MetaMons competitive notes

Muk is a poison-type Pokémon whose base stats lean toward HP — at 500 BST it is a strong total for competitive play, with slow (base 50) and a physical attacking profile. Its Stench ability matters more than the raw numbers when it hits the field: check what it does before deciding between a sweeper, pivot, or support role for Muk. Build around what Muk actually threatens, not its in-game lore — start from its weaknesses and strongest STAB moves, then decide whether its Speed, bulk, or coverage justifies a team slot.
