Strategy & play
How Cloyster plays — derived from its stats and the rules of the game, not an opinion.
- Inflicts Paralysis — the Defending Pokémon can’t attack or retreat for a turn. A reliable one-turn lock; chain it to stall the opponent out.
- Its main attack (Guard Press) needs 3 Energy — a turn-3 swing on manual attachment — you’ll want Energy acceleration to power it up on time.
- Needs Water Energy to attack — your line must supply that color.
- Water type, weak to Grass ×2 — a Grass attacker doing ≥60 effectively one-shots it.
- A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
- Retreat cost 3 — gets stranded Active if gusted; run Switch / Escape Rope or a Float Stone-style Tool.
How to beat Cloyster
- Exploit its Grass weakness — ≥60 damage one-shots it.
- Gust it before the evolution is set up.
- Trap it Active — 3 retreat means it can’t escape without help.
- On the receiving end of a condition? Retreat, switch, or evolve to wipe it — conditions only stick to the Active.

Frequently asked
How can I tell if my Cloyster is real?
Cloyster is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the back-light test (real cards have a black inner layer that blocks light; counterfeits glow through), the rosette dot pattern on the back under magnification, font weight and kerning on the card name, and the holofoil pattern if applicable. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.
