MetaMons competitive notes

Shellos is a water-type Pokémon whose base stats lean toward HP — at 325 BST it is a low total for competitive play, with slow (base 34) and a mixed attacking profile. Its Sticky Hold 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 Shellos. Build around what Shellos 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.
