MetaMons competitive notes

Koffing is a poison-type Pokémon whose base stats lean toward Defense — at 340 BST it is a low total for competitive play, with slow (base 35) and a mixed attacking profile. Its Levitate 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 Koffing. Build around what Koffing 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.
