MetaMons competitive notes

Tentacool is a water/poison-type Pokémon whose base stats lean toward Special Defense — at 335 BST it is a low total for competitive play, with mid-pack speed (base 70) and a mixed attacking profile. Its Clear Body 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 Tentacool. Build around what Tentacool 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.
