MetaMons competitive notes

Cloyster is a water/ice-type Pokémon whose base stats lean toward Defense — at 525 BST it is a strong total for competitive play, with mid-pack speed (base 70) and a mixed attacking profile. Its Shell Armor 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 Cloyster. Build around what Cloyster 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.
