Japanese Inferno X (M2): prices, chase cards and booster box guide

The short version

Inferno X, set code M2, is the Japanese expansion whose cards went into the English Phantasmal Flames. As of mid-September 2026 the Mega Charizard X ex Special Art Rare sells for about $712 on the US market, and the gold Mega Ultra Rare of the same Pokémon for about $699. Those two cards make up about 89 percent of what one copy of every card in the set costs. The third most valuable card is about $27.

The booster box is about $112 for 30 packs of 5 cards, and a loose pack is about $3.92. 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 everything costs today and how it compares with English. If you want one of the two Charizards, the single is the only certain route. If you want to open a box, budget it as entertainment.

What Inferno X is

The official product page gives a release date of September 26, 2025, a suggested price of 180 yen per pack including tax, and 5 cards per pack, inserted at random. It states no box size and no box price. Bulbapedia's set page calls it the second expansion of the Japanese MEGA Series and says each booster box contains 30 packs, so a box holds 150 cards. Thirty packs at 180 yen works out to 5,400 yen, which is arithmetic, not a quoted box price.

The numbered set is 80 cards, with 36 secret cards above it, for 116 in all. Bulbapedia's list puts the secrets at 12 Art Rares (#81 to #92), 17 Super Rares (#93 to #109), 6 Special Art Rares (#110 to #115) and a single Mega Ultra Rare, #116. The set page agrees, with one wrinkle: TCGplayer files Switch #102 as a Promo, so the site shows 16 Super Rares plus that one card.

Bulbapedia states that the cards released in Inferno X are included in Phantasmal Flames, which came out in English on November 14, 2025, seven weeks later. The mapping is close but not one to one. Its Phantasmal Flames page says the English set also takes cards from two Japanese MEGA Starter Sets, and it runs to 94 numbered cards and 130 in all. Going by the two lists, the English Meowth and Paldean Wooper Illustration Rares are not in Inferno X, the Charcadet Art Rare is not in Phantasmal Flames, and one Special Art Rare reached English in a different product, covered below.

The numbers

These are the live figures from the set page. Every one is a US TCGplayer market price for the Japanese printing, not a price in Japan.

The median card is worth about 14 cents, 7 cards clear $10 and only 2 clear $50. One of every card at market costs about $1,588, and the two top Mega Charizard X ex cards account for about $1,410 of it. The other 114 cards together cost about $178.

The 6 Special Art Rares average about $133, but that is one $712 card and five others from about $9.64 to about $27. The single Mega Ultra Rare is about $699. The 16 Super Rares average about $3.05, the 12 Art Rares about $2.43 and the 8 Double Rares about 70 cents. Commons, uncommons and rares average between 9 and 18 cents.

Chase cards

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

The Special Art Rare Mega Charizard X ex, #110, leads at about $712. The gold Mega Ultra Rare #116 is close behind at about $699. After that the prices drop sharply: Oricorio ex #111 at about $27, the full-art Mega Charizard X ex #94 at about $26, and Dawn #115, a Supporter, at about $23. Mega Sharpedo ex #113 is about $14.55, Rotom ex #112 about $11.92 and Mega Lopunny ex #114 about $9.64.

Below the table, the best Art Rare is Piplup #85 at about $6.43, and the full-art Dawn #106 is about $5.50. Four of the eleven most valuable cards are Mega Charizard X ex, down to the regular Double Rare #13 at about $3.24. The site has no Japanese pull-rate data, so it cannot put odds on any of these cards.

Japanese versus English prices

All prices here are as of mid-September 2026, and every pair is the same artwork in the same role. We checked Bulbapedia's card pages for Mega Charizard X ex, Dawn and Piplup. The other pairs match by name and rarity tier across the two set lists.

The Special Art Rare Charizard is about $712 in Japanese (#110) and about $696 as the English Special Illustration Rare (#125), close to parity. The gold card is where the languages split: the Japanese Mega Ultra Rare #116 is about $699 and the English Mega Hyper Rare #130 about $254, so the Japanese copy sells for about 2.7 times the English one. This site's English pull rates, taken from published pack-opening counts, put the Mega Hyper Rare at about 1 in 1,260 packs. There is no Japanese figure to set beside it, so this guide reports the gap without explaining it.

The full-art Charizard is about $26 in Japanese (#94) against about $22 in English (#109), and the Dawn Special Art Rare about $23 (#115) against about $19 (#129). The regular Double Rare #13 runs the other way, about $3.24 against $5.24, and so do three more Special Art Rares: Mega Sharpedo ex is about $14.55 against $17.73 (#127), Rotom ex about $11.92 against $16.08 (#126), and Mega Lopunny ex about $9.64 against $14.24 (#128). Among the Art Rares, Piplup is about $6.43 (#85) against about $12.46 for the English Illustration Rare (#98).

Oricorio ex #111 has no twin in Phantasmal Flames. Bulbapedia's card page says that artwork reached English as MEP Black Star Promo 024 in the Mega Charizard X ex Ultra-Premium Collection. A promo packed in a collection is not a pack pull, so it is not compared here.

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 $112. At the 30 packs Bulbapedia gives, that is about $3.74 a pack, against about $3.92 for a loose pack. For scale, the English Phantasmal Flames booster box is about $398 for 36 packs of 10 cards. A Japanese box holds 150 cards and an English box 360, so those prices describe different products.

What a box guarantees, going by the sources: 30 packs of 5 randomly inserted cards, and nothing more. The official page promises no rarity per pack or per box, and Bulbapedia's set page states no box pattern either. Shop blogs publish per box hit counts and odds for this set, but a shop blog is not a source this site uses for odds, so none of those figures appear here. The sealed EV board covers English products only and says nothing about this box.

Do not judge the box by its wrap. Our resealed product guide has the background: Screen Rant reported in March 2025 that Pokémon Center stores in Japan remove the plastic wrap from booster boxes at sale, so a listing that says "without shrink" is not evidence of tampering by itself. It also 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 Poké Ball logo wrap test for English boxes does not apply.

How to buy it

Every Japanese card and product page shows the US market price, a price history from September 18, 2026, the price that counts as 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 is capped at 12 percent under market on the item price and the second has no cap. Both are affiliate links. The block below opens the capped searches for this set's booster box and booster pack.

The cap is on the item price, so add shipping yourself. A listing counts as below market only when the landed price is at least 12 percent under market: about $99 delivered for the box. The methodology only scores items with a market price of at least $5, so a lone pack at about $3.92 sits outside it. 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.

Because the buttons are limited to US sellers, those listings 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. Check the language too: Bulbapedia lists Korean and Traditional Chinese versions of Inferno X, both official products, so confirm the Japanese text and the Japanese back from the photos.

For singles, site prices are raw Near Mint, and a Lightly Played copy is measured against 85 percent of market. A Near Mint Special Art Rare Charizard #110 has to land near $626 to count as below market, and a Lightly Played one near $532. eBay's Authenticity Guarantee covers trading cards sold for $200 or more in the US. In this set that means the two top Charizards and nothing else, and it does not cover boxes or packs. At these prices, read how to spot fake cards before you pay.

Who it suits

• Charizard collectors who want the Japanese Special Art Rare or gold card. Both are single card purchases near $700.
• People who want a box to open at about $112: 30 small packs, with no promise about what is inside.
• Art Rare collectors on a budget. All 12 Art Rares together cost about $29 at market.
• Completists: about $1,588 for all 116 cards, of which about $178 buys everything except the two Charizards.
• Players should look elsewhere. Japanese cards are not legal at US Championship Series events.

Bottom line

Inferno X is the Japanese expansion whose cards went into Phantasmal Flames, which also draws on two MEGA Starter Sets. It has 80 numbered cards and 36 secrets, and comes in 5 card packs at 180 yen and 30 pack boxes. On the US market it is a box at about $112 and a set where two Mega Charizard X ex cards near $700 hold about 89 percent of the value. The Special Art Rare costs about the same in both languages, the gold card about 2.7 times as much in Japanese, and three of the other Special Art Rares less. No expected value exists for the box, and no source we rely on states a box guarantee. 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.
