10 Hardest Slowpoke Pokémon Cards to Pull
Ranked by estimated pull rates from English booster packs.
Slowpoke’s collection ranges from its relaxed TAG TEAM with Psyduck to patterned foil versions of ordinary cards. Master Ball, Poké Ball and other finishes are distinct collecting targets. This guide compares their existing English estimates and identifies the precise version beside each figure.
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 Slowpoke ever printed; nearby estimates may not represent a real difference in difficulty.

This Aquapolis 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 151 eligible reverse printings. This simplifies special-card replacements and unequal print sheets; the slot allowance is a modelling assumption.

This reverse holo offers a smaller collecting target alongside Unbroken Bonds’ GX chases. Its estimated chance concerns this particular number and finish, not the probability of finding any reverse holo.
Where this estimate comes from
Assumes 1 effective ordinary reverse-holo slots per pack, shared equally across 179 eligible reverse printings. This simplifies special-card replacements and unequal print sheets; the slot allowance is a modelling assumption.

This entry ranks the Poké Ball Pattern version of 018/131. The ordinary and other patterned finishes are separate collecting targets. A shared artwork scan may not show the selected foil, so match the actual pattern as well as the number.
Where this estimate comes from
The estimated rarity frequency is divided across the eligible cards in that pool, assuming equal individual chances. It is not a measured count of this particular card.

Psyduck and Slowpoke share the rainbow treatment on this secret TAG TEAM. Number 239/236 distinguishes it from both full-art versions in Unified Minds. Its very-low-confidence estimate uses an assumed rarity frequency.
Where this estimate comes from
Illustrative starting assumption: one Rare Rainbow group hit in about 80 packs, shared equally across 13 eligible cards. No measured rate supports this assumed frequency; use it only as a rough scenario.

How we compare Slowpoke 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 Slowpoke 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.
Slowpoke pull-rate questions
Which Slowpoke card is hardest to pull?
Slowpoke (Master Ball Pattern) 18/131 (Prismatic Evolutions, Holofoil) has the lowest estimated chance among the qualifying cards here: about 1 in 1,400 packs. This is the current model’s ordering, including any rough assumptions labelled above. It does not cover every Slowpoke ever released.
Will opening 1,400 packs guarantee the top-ranked card?
No. For the first card listed at rank 1, opening 1,400 independent packs gives an estimated 64.2% 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 Slowpoke 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 Slowpoke guide compares available raw prices instead.
Do a booster box or an Elite Trainer Box guarantee a Slowpoke?
These estimates do not establish any product-level guarantee. A named Slowpoke 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 Slowpoke 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.
