10 Hardest Cloyster Pokémon Cards to Pull
Ranked by estimated pull rates from English booster packs.
Cloyster’s older holo and reverse-holo printings add variety beyond its ordinary set appearances. A shared illustration can belong to multiple finishes or numbered cards. This countdown keeps those English identities separate while comparing the existing estimated odds.
Pull rates are estimates—see how this ranking works.
Estimated odds, limited coverage. This uses the same estimates as our pull-rate calculators, including labelled rough models and very-low-confidence assumptions. It does not establish the hardest Cloyster ever printed; nearby estimates may not represent a real difference in difficulty.

This BREAKpoint printing adds a reverse-holo version to the Pokémon’s checklist. The estimate concerns the exact collector number shown. An ordinary card with the same artwork does not count as this foil pull.
Where this estimate comes from
Assumes 1 effective ordinary reverse-holo slots per pack, shared equally across 99 eligible reverse printings. This simplifies special-card replacements and unequal print sheets; the slot allowance is a modelling assumption.

The reverse holo is a separate finish of this numbered 151 card, rather than an illustration rare. A shared artwork image does not show every foil difference, so match the finish as well as the collector number.
Where this estimate comes from
Assumes 1.5 effective ordinary reverse-holo slots per pack, shared equally across 153 eligible reverse printings. This simplifies special-card replacements and unequal print sheets; the slot allowance is a modelling assumption.

How we compare Cloyster pull rates
We compare the chance of pulling one exact card from one English pack of its release. A rarity’s overall hit rate is different from the odds of finding a particular Cloyster within that rarity. Evidence ranges from reported community openings and print-sheet models to rough comparisons and assumed rarity frequencies. Each rough estimate carries its warning beside the odds; expand its explanation for the actual basis.
Japanese cards, guaranteed promos, deck cards and box toppers are outside this ranking. Vintage editions with shared odds take one position. Distinct pack-pulled finishes can qualify separately. Prices do not affect the order, and a missing price does not remove an otherwise eligible card.
Up to ten cards are selected automatically from available estimates, with any tie at the cutoff kept together. Estimates are rounded to two significant digits for comparison, not presented as precise measurements. New cards can enter when a matching printing and estimate are available; prices refresh with the catalogue. Descriptions stay with their card when the order changes.
Cloyster pull-rate questions
Which Cloyster card is hardest to pull?
Cloyster 51/264 (Fusion Strike, Reverse Holofoil) has the lowest estimated chance among the qualifying cards here: about 1 in 220 packs. This is the current model’s ordering, including any rough assumptions labelled above. It does not cover every Cloyster ever released.
Will opening 220 packs guarantee the top-ranked card?
No. For the first card listed at rank 1, opening 220 independent packs gives an estimated 63.8% chance of at least one copy. The average waiting time is not a promise; actual packs and factory collation can behave differently from this model.
Is the hardest Cloyster to pull also the most expensive?
Not necessarily. Artwork, demand, condition and how much product exists also matter to collectors. This guide ranks estimated pack odds. Our most expensive Cloyster guide compares available raw prices instead.
Do a booster box or an Elite Trainer Box guarantee a Cloyster?
These estimates do not establish any product-level guarantee. A named Cloyster promo included in a product is separate from the random cards inside its booster packs. Use the exact-card calculator to explore pack quantities and its stated assumptions.
Why can a reverse-holo Cloyster rank above a rarer-looking card?
This compares one exact printing. A large reverse-holo pool can make a particular card’s modelled chance small even when reverse holos overall are common. Most of these estimates assume equal chances within the pool. That does not prove this Pokémon is short-printed, and it does not describe the ordinary non-holo version.
