Japanese Tag All Stars (SM12a): prices, chase cards and box guide

The short version

TAG TEAM GX: Tag All Stars, set code SM12a, is the High Class Pack that closed out the Sun & Moon era in Japan on October 4, 2019. It is a retrospective of the TAG TEAM GX years: mostly reprints, with 53 secret cards on top. It has no single English counterpart: the Pokémon and TAG TEAM Supporters that debuted in it went into Cosmic Eclipse, and its reprints trace back to earlier English sets. As of mid-September 2026 the booster box sells for about $944 on the US market and a loose pack for about $116.

The most valuable card is not a TAG TEAM. It is Sightseer #192, a full art Supporter at about $800, and the four most expensive cards in the set are all Trainer cards. Pullnomics has no Japanese pull-rate data and computes no expected value for Japanese products, so this guide cannot say what a box returns on average, only what things cost today. If you want a particular card, buy the single. If you open a box, count the price as the cost of the entertainment.

What Tag All Stars is

The official product page gives a release date of October 4, 2019, a price of 500 yen plus tax per pack and 11 cards per pack, with a TAG TEAM GX or another Pokémon GX promised in every pack. Bulbapedia's set page adds that the eleven cards, up from the usual five, include two holofoil cards, one Energy card and one parallel foil card. The official pages we read do not give a box size. The Japanese card news site pokecanews.com listed the box at 10 packs for 5,000 yen before tax, exactly ten times the official pack price, which makes a box 110 cards.

Bulbapedia calls Tag All Stars the nineteenth and final subset of the Sun & Moon era in Japan, a retrospective of the TAG TEAM block with reprints from Tag Bolt, Double Blaze, Miracle Twin and four subsets. The numbered set is 173 cards with 53 secret cards above it, 226 in all, and the counts on this site agree: 37 Super Rares, 9 Hyper Rares and 7 gold Ultra Rares.

Bulbapedia says every Pokémon that debuted in Tag All Stars, along with its two new TAG TEAM Supporter cards, was released in English in Cosmic Eclipse, which arrived on November 1, 2019, four weeks later. The reprints sit wherever their originals went in English. Of the ones we checked, Sightseer's original print is in Lost Thunder, Green's Exploration's is in Unbroken Bonds and the regular Mewtwo & Mew GX is in Unified Minds.

The set page lists 353 entries, not 226. Bulbapedia notes that each card without a rarity symbol also has a Mirror Holofoil variant. The site lists a parallel as its own card, with the pattern in brackets, as in Mimikyu (Mirror Holofoil) #63, and it has no rarity on file for 261 of the 353 listings.

The numbers

Each figure below is a US TCGplayer market price for the Japanese printing, not a price in Japan.

Of the 353 listings, 327 have a market price. The median is about $1.45, 46 listings clear $10, 21 clear $50 and 13 clear $100. One of every priced listing at market costs about $5,253 as of mid-September 2026.

About 86 percent of that sits in the secret cards. The 34 priced Super Rares average about $109 and add up to roughly $3,693, about 70 percent of the set on their own. The four priced gold Ultra Rares average about $129 and the six priced Hyper Rares about $51. Below them the 22 Double Rares, the tier that holds regular GX prints, average about $11.45, the 17 Prism Rares about $4.77, and the 244 priced listings with no rarity on file about $1.65.

Nine secret cards have no market price right now: three Super Rares, three Ultra Rares and three Hyper Rares. The $5,253 total leaves them out.

Chase cards

These are the eight most valuable listings right now.

Sightseer #192 leads at about $800. Green's Exploration #196 is second at about $463, then Erika's Hospitality #190 at about $450 and Misty & Lorelei #191 at about $398. Those four Supporters add up to about $2,111, roughly 40 percent of the set's listed value. The first Pokémon is Togepi & Cleffa & Igglybuff GX #186 at about $240, followed by the gold Reshiram & Charizard GX #220 at about $221, Blue's Strategy #193 at about $209 and Umbreon & Darkrai GX #181 at about $169. Blue's Strategy is TCGplayer's name for the card Bulbapedia lists as Blue's Tactics.

The top two Supporters carry artwork that Bulbapedia lists only in Japanese. Its Sightseer page records the original Lost Thunder print by Naoki Saito and a Full Art by the same artist released in the Japanese Tag All Stars subset. It lists no English full art. Green's Exploration is similar: English has a Naoki Saito full art, Unbroken Bonds #209, while Bulbapedia's page for the card describes Tag All Stars #196 as a new Full Art by TOKIYA.

Match the number before you pay. Both cards also appear here as ordinary prints, Sightseer as #149 and Green's Exploration as #154. The site has no odds for any secret card, and with 53 of them no box promises a specific one.

Japanese versus English prices

All prices here are as of mid-September 2026. Because the set has no English twin, this section pairs only what the sources support.

The one match we confirmed is Mewtwo & Mew GX. Bulbapedia's card page says the Regular print, the Mitsuhiro Arita artwork that English lists as Mewtwo & Mew-GX, Unified Minds #71, was reprinted in Tag All Stars, where it is #52. The Japanese copy is about $39, the most valuable Double Rare in the set. The English copy is about $139.

What cannot be paired:

• Sightseer #192 and Green's Exploration #196 have no English printing with the same artwork, going by the Bulbapedia pages above.
• Misty & Lorelei #191 is a Full Art, and Bulbapedia's page for the card says only the Regular print went into Cosmic Eclipse.
• We did not check Erika's Hospitality, Blue's Strategy or the gold cards print by print, so do not assume an English full art or gold print is the same card.
• The official page advertises Super Rares with newly drawn illustrations and names Eevee GX and Dedenne GX, so each Super Rare Pokémon needs its own check.

Neither language is the better buy. They are separate markets, and Japanese versus English cards explains why one artwork can carry two prices.

Sealed product

The booster box is about $944. At 10 packs that is about $94 a pack, against about $116 for a loose pack, so ten loose packs would cost about $1,160. The lowest TCGplayer asking price in our data is about $1,500, well above the market figure, which reflects recent sales. This is a 2019 product, and part of its sealed price is a collector premium for the sealed box itself.

What a box guarantees, going by the sources: 10 packs of 11 cards, a TAG TEAM GX or Pokémon GX in every pack, and at least one card of SR or better in the box. It does not guarantee any particular secret card. The official page says rarity rates differ from a regular expansion and publishes none. Bulbapedia puts so-called god packs, 10 Super Rares plus the Energy card, at roughly 1 in 250 packs. The official page gives no such figure, so treat it as a community estimate. The sealed EV board covers English products only.

Do not judge the box by its wrap. Our resealed product guide explains why: Screen Rant reported in March 2025 that Pokémon Center stores in Japan remove the plastic wrap at sale, and we found no authoritative description of Japanese factory wrap. A bare box is not proof of tampering, and wrap alone does not prove a box is untouched. 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.

How to buy it

Each Japanese card and product page shows the US market price, a price history that starts on September 18, 2026, the price 12 percent below market, and two eBay buttons. Both open eBay filtered to Buy It Now listings from US sellers whose titles say Japanese, JPN or JP, with proxies, lots and other languages excluded, sorted by price plus shipping. The first caps the item price at 12 percent under market, the second has no cap, and both are affiliate links. The block below opens the capped searches for this set's booster box and booster pack.

The cap applies before shipping, so add shipping yourself. A listing counts as below market only when the landed price is at least 12 percent under market: about $831 delivered for the box and about $102 for a pack. If the capped search is empty, nothing is listed below market at that moment. Use the second button to see every current price, then eBay's "Save this search" so eBay emails you new matches.

Listings from US sellers have no import step. If you widen the search to sellers in Japan, a shipment of any value can now pick up import charges, so find that line at checkout before you pay.

For singles, site prices are raw Near Mint. Under the methodology a Lightly Played copy is measured against 85 percent of market, so a Near Mint Sightseer #192 has to land near $704 to count as below market and a Lightly Played one near $598. eBay's Authenticity Guarantee covers trading cards sold for $200 or more in the US, which takes in seven cards in this set at today's prices. It does not cover boxes or packs. Confirm the language from photos of the front and back, and read how to spot fake cards before you pay three figures for a Supporter.

Who it suits

• Collectors of the full art Supporters: Bulbapedia lists the Sightseer #192 and Green's Exploration #196 artwork only in Japanese.
• People who want to open a box: about $944 for 110 cards, with no promise of any particular card.
• Completists and TAG TEAM GX collectors should know the scale: a 226 card checklist, 353 listings with parallels, about $5,253 for the priced ones and nine secret cards with no current price.
• Players should look elsewhere. Japanese cards are not legal at US Championship Series events.

Bottom line

Tag All Stars is the Sun & Moon era's closing High Class Pack: 10 packs of 11 cards in a box of about $944, with at least one SR or better promised per box. Its value sits in 53 secret cards, led by four Super Rare Supporters from Sightseer at about $800 to Misty & Lorelei at about $398. The one English match we confirmed, Mewtwo & Mew GX, is about $39 in Japanese against about $139 in English. No expected value exists for the box, so open one only if opening it is the point. For a specific card, start from the set page or the Japanese index and compare landed prices with the Japanese market price only.
