Japanese Eevee Heroes (S6a): prices, chase cards and box guide

The short version

Eevee Heroes, set code S6a, is a small Japanese Sword & Shield set from May 2021 built around the eight evolutions of Eevee. The Eeveelution cards English collectors know from Evolving Skies appeared here first. As of mid-September 2026 a sealed booster box sells for about $841 on the US market, for 30 packs of 5 cards, and a loose pack for about $25.

That is a lot of money for 150 cards, and Pullnomics cannot say what they are worth on average, because the site has no Japanese pull-rate data and computes no expected value for Japanese products. What the prices do show: ten cards hold about 85 percent of the value the site can price, and the median card is worth 30 cents. If you want those cards, buy them as singles. A box or a pack is expensive entertainment.

What Eevee Heroes is

The official product page gives a release date of May 28, 2021, a price of 165 yen per pack and 5 cards per pack, plus one puzzle card from a promotion that ran with the set. It gives no pack count for a box. PokeBeach, describing a Pokémon Center bundle, counted two booster boxes as 60 packs, so a box is 30 packs and 150 game cards.

Bulbapedia's set page calls it an Enhanced Expansion Pack, a subset and not a main expansion, with 101 cards. PokeBeach reported 69 cards before the secret ones, with all eight Eeveelutions as Pokémon V and Umbreon, Leafeon, Glaceon and Sylveon also as Pokémon VMAX. On the set page that works out to 8 Double Rares (the regular V cards), 4 Triple Rares (the regular VMAX cards) and 32 cards numbered above 69: 18 Super Rares, 10 Hyper Rares and 4 gold Ultra Rares.

The English counterpart is only a partial match. Bulbapedia's Evolving Skies page says the English set, released August 27, 2021 with 237 cards, was built from the Japanese sets Skyscraping Perfection and Blue Sky Stream, plus some cards from Eevee Heroes and leftovers from three other Japanese sets. It adds that some Eeveelution cards skipped Evolving Skies and came out in English as promos. So Evolving Skies, which arrived thirteen weeks after Eevee Heroes, is the English home of the chase cards below, but it is a far larger set.

The numbers

These are the live figures from the set page, all US TCGplayer market prices for the Japanese printing and not prices in Japan.

The site has a market price for 98 of the 101 cards. The median is 30 cents, 21 cards clear $10 and 10 clear $50. One of every priced card costs about $2,055.

The 69 cards up to the printed total, regular V and VMAX cards included, add up to about $44, and the 4 gold Ultra Rares to about $27. The 18 Super Rares average about $68 and total about $1,221. The 7 priced Hyper Rares average about $109 and total about $763. Those two tiers are more than 95 percent of the priced value, and the ten cards above $50 alone are about $1,746, or 85 percent. The three unpriced cards are all Hyper Rares, so a complete set costs more than that.

Chase cards

These are the eight most valuable priced cards in the set right now.

Glaceon VMAX #91 leads at about $370, ahead of Leafeon VMAX #89 at about $306 and Umbreon V #85 at about $287. Then come Sylveon V #83 at about $152, Espeon V #81 at about $136, Glaceon V #77 at about $117, Flareon V #73 at about $108 and Leafeon V #71 at about $98. Vaporeon V #75 (about $94) and Jolteon V #79 (about $78) complete the ten, and then the list falls to about $42 for Umbreon VMAX #94.

The Eeveelution V cards come in pairs of Super Rare printings with consecutive numbers, and the gap inside each pair is wide. Bulbapedia's card pages identify Umbreon V #84 and Espeon V #80 as the standard full art and #85 and #81 as the special full art by a different illustrator. Umbreon V #84 is about $38 against $287 for #85. Pairs we did not check show the same split, Sylveon V #82 at about $24 against $152 for #83 and Glaceon V #76 at about $18 against $117 for #77, so reading every odd number from #71 to #85 as the special full art is an inference. Bulbapedia also lists Glaceon VMAX #91 and Leafeon VMAX #89 as special full arts and the numbers just below them as rainbow versions.

Two chase cards are missing. As of mid-September 2026 three Hyper Rares have no market price in our data: Sylveon VMAX #92 and #93 and Umbreon VMAX #95. Bulbapedia lists #95 as the special full art Umbreon VMAX, the most expensive card in English Evolving Skies, and #93 as the special full art Sylveon VMAX. This guide does not guess at either price. Treat the table above as incomplete at the top.

Japanese versus English prices

All prices are as of mid-September 2026. Each pair was matched on Bulbapedia's page for the card, which lists both numbers and every print's illustrator.

• Umbreon V, special full art: about $287 in Japanese (#85), about $386 in English (#189).
• Espeon V, special full art: about $136 in Japanese (#81), about $241 in English (#180).
• Leafeon VMAX, special full art: about $306 in Japanese (#89), about $410 in English (#205).
• Glaceon VMAX, special full art: about $370 in Japanese (#91), about $313 in English (#209).
• Umbreon VMAX, regular: about $8.21 in Japanese (#48), about $29 in English (Evolving Skies #95).

Four of the five are cheaper in Japanese and one is dearer, so no rule carries over to the next card. The special full art Umbreon VMAX (about $2,283 in English, #215) and Sylveon VMAX (about $384, #212) cannot be compared, because our data has no price for the Japanese copies. None of this makes either language the better buy. They are separate markets, and Japanese versus English cards explains why the same artwork carries two prices.

Sealed product

The booster box is about $841. At 30 packs that is about $28 a pack, while a loose pack is about $25. Thirty loose packs would cost about $736, so roughly $105 of the box price is a premium for an intact box from a 2021 set. English Evolving Skies shows the same gap on a bigger scale: about $68 a pack in a $2,450 box of 36, against about $46 for a loose pack.

Two bundles are tracked by price only. The VMAX Special Set is about $286. PokeBeach reported it as eight Eevee Heroes packs plus a promo pack with one of four full art VMAX cards (Vaporeon, Jolteon, Flareon or Espeon), at 1,870 yen. Eight loose packs cost about $196. The Gym Box is about $2,078. US shop listings describe it as a Pokémon Center bundle with two booster boxes, which fits the Eeveelution Set PokeBeach reported at 11,330 yen: two boxes, accessories and the promo pack. No official page confirmed that for us, so check the contents of any listing. Two boxes alone cost about $1,682.

What a box guarantees, going by the sources: 30 packs of 5 cards. The official page, Bulbapedia and PokeBeach state no guaranteed Super Rare, Hyper Rare or special full art per box, and the hit counts that circulate for Japanese boxes are hobby lore we could not source. The sealed EV board covers English products only, and even the English pull rates behind it group special full arts with every other card of the same printed rarity, so there are no measured odds for a specific special art in either language.

Do not judge the box by its wrap. As our resealed product guide explains, a Japanese box without shrink wrap is not proof of tampering, but it leaves no outer seal to inspect. Importers' rule of thumb is that many Japanese boxes open through a cardboard tear strip that cannot be put back, so ask for a photo of it. The same guide flags loose packs from expensive sets, because a loose pack cannot show where it came from.

How to buy it

Each Eevee Heroes card and product page carries the US market price, a price history that begins on September 18, 2026, the figure that counts as 12 percent below market, and two eBay buttons. They search Buy It Now listings from US sellers with Japanese, JPN or JP in the title, leave out proxies, lots and other languages, and sort by price plus shipping. The first caps the item price at 12 percent under market and the second drops the cap. Both are affiliate links. The block below runs the capped search for the booster box and booster pack.

Shipping is not part of the cap, so add it yourself. The test is the landed price: at least 12 percent under market, which for the box means about $740 delivered. An empty capped search means nothing is listed below market right now. Open the uncapped button to see what sellers are asking, and use eBay's "Save this search" so eBay emails you new matches.

Listings from US sellers have no import step. If you look at sellers in Japan instead, a shipment of any value can now pick up import charges, so find that line at checkout before you commit.

Card prices here are raw Near Mint, and the methodology measures a Lightly Played copy against 85 percent of market. A Near Mint Umbreon V #85 has to land near $253 to count as below market, a Lightly Played one near $215. eBay's Authenticity Guarantee covers trading cards sold for $200 or more in the US, the range of Glaceon VMAX #91, Leafeon VMAX #89 and Umbreon V #85, so look for its badge. It does not cover boxes or packs. Confirm the language from photos of both sides, and read how to spot fake cards before paying three figures for a single.

Who it suits

• Eeveelution collectors who want a Japanese special full art. Buy the single: the ten priced above $50 run from about $78 to about $370.
• Collectors on a budget. The 69 card numbered set is about $44, and the regular Umbreon VMAX #48 about $8.
• Sealed collectors who accept a premium of about $105 for an intact box that may have no outer seal to check.
• Pack openers get 5 cards for about $25 and no documented odds.
• Players should look elsewhere: Japanese cards are not legal at US Championship Series events.

Bottom line

Eevee Heroes is a 101 card Japanese set in which ten cards hold about 85 percent of a roughly $2,055 priced checklist and the 69 numbered cards cost about $44 together. A box is about $841 for 30 five card packs, with no expected value, no documented guarantee and a premium of about $105 over loose packs. Most matched cards are cheaper in Japanese than in English Evolving Skies, Glaceon VMAX is not, and the Japanese special full art Umbreon VMAX and Sylveon VMAX have no price in our data. For a specific card, start from the set page or the Japanese index, use the eBay buttons there, and compare landed prices with the Japanese market price only.
