- Cloyster's Water / Ice typing is best attacked with Electric (2x), Grass (2x), Fighting (2x). Start with those attacking types when choosing moves or counter Pokémon.
- Avoid relying on common Ice, Water attacks unless they have unusually high power or a secondary purpose, because Cloyster resists or ignores those matchups.
- This guide uses the modern Gen 6+ type chart only. Abilities, held items, Terastallization, weather, fields, and special move rules can still change real battle outcomes.
