Cloyster (ecard1-42, Rare) is a Stage 1 Water-type Pokémon from the Expedition Base Set that evolves from Shellder. It has a low-damage coin-flip attack that can Paralyze and a higher-risk attack that flips four coins to deal 20 damage per heads. Its role leans toward disruptive status play and potential high burst damage with coin luck, tempered by a two Colorless retreat cost and Metal weakness.
