Sealed Storm Emeralda booster box (Mega Rayquaza ex on the packaging)
“Storm Emeralda” is an expansion pack (set code: m6) for the Pokémon Trading Card Game MEGA Series released in Japan on July 31, 2026. The package mascot is Mega Rayquaza ex. A portion of the included cards will be reorganized and included in the English version “Delta Reign,” scheduled for release on November 6, 2026. However, because the number of cards in the regular set and the allocation of promo cards differ, the two sets do not contain identical content.
This article summarizes the complete list and market prices of all 37 Secret cards, highlighted cards, inclusion differences compared to Delta Reign, pull rates, and purchase methods.

Highlighted Chase Cards
Mega Rayquaza ex MUR (113/076) — the most valuable card in the set
Mega Rayquaza ex SAR (110/076)
Raikou ex SAR (108/076)
Zinnia’s Trust SAR (112/076)
Kyogre AR (080/076) — moves to an ETB promo in the English Delta Reign set
Groudon AR (084/076)
Mega Rayquaza ex SR (095/076) — the competitive-play version
- Mega Rayquaza ex MUR (113/076): The most valuable card in this set, and the only MUR included in Storm Emeralda. Secondary market surveys estimate its pull rate at approximately 1 in 50 Booster Boxes. On the initial release date, Card Rush listed its buyback price at ¥260,000, which subsequently declined by late August to a buyback price of ¥100,000 and a selling price of ¥148,000. The gold-themed exclusive illustration combined with the immense popularity of Rayquaza is considered the driving factor behind its high value.
- Mega Rayquaza ex SAR (110/076): From an initial buyback price of ¥110,000, it settled by late August to a buyback of ¥45,000 and a selling price of ¥58,800. Following precedents where past high-rarity Rayquaza cards (such as Rayquaza VMAX SA) trade at premium prices, some market observers expect sustained collector demand.
- Raikou ex SAR (108/076): Priced at ¥7,480 selling, making it the second most expensive SAR after Mega Rayquaza.
- Zinnia’s Trust SAR (112/076): Features a character deeply tied to Rayquaza in Omega Ruby and Alpha Sapphire. Illustrated by Teeziro. Selling price is ¥2,780.
- Kyogre AR & Groudon AR (080 & 084): Art Rares of the Hoenn Legendary Pokémon, both selling for ¥1,780. The Kyogre AR is excluded from the main set in the English version “Delta Reign” and is scheduled to be included as an Elite Trainer Box promo.
- Mega Rayquaza ex SR (095/076): Selling price of ¥4,580. It features the attack “Storm Emeralda,” which scales in damage based on the amount of Fire and Lightning Energy in play, generating competitive play demand.
Relationship & Inclusion Differences Between Storm Emeralda and Delta Reign
“Delta Reign” is the English version officially announced on August 20, 2026, featuring cards from the Japanese set Storm Emeralda. However, the two sets do not contain identical content.
| Item | Storm Emeralda (Japan) | Delta Reign (English) |
|---|---|---|
| Release Date | July 31, 2026 | November 6, 2026 |
| Regular Cards | 76 types | 103 types (Mega Rayquaza ex is 084/103) |
| Total Cards | 113 types | “135+ cards” (Official Announcement) |
| Additional Content | — | Cards derived from Starter Set MEGA (Eevee ex, Zoroark ex, Meowscarada ex) |
| Pack & Box | 5 cards × 30 packs | 10 cards × 36 packs |
| Kyogre AR | Included as 080/076 | Scheduled as ETB Promo |
According to the disclosed English card numbers, Delta Reign’s regular card set consists of 103 types. This is 27 types more than Storm Emeralda’s 76 types, with the additions containing cards derived from Japanese MEGA Starter Sets. Conversely, because cards like Kyogre AR are shifted to promos, it is not a simple matter of adding 27 cards to the set. Card numbers between the Japanese and English versions do not correspond; it is accurate to view them as “different products reorganized from the same card pool.”
Because the Japanese version circulates first, its market price is established earlier and is used to predict prices for the English version. Please note that card language eligibility for official tournaments varies depending on the region and tournament classification. Even after the English cards are released, Japanese cards are not guaranteed to be usable in overseas official tournaments, so please check the rules of the specific tournament you plan to attend. For background on price differences between Japanese and English cards, refer to our article explaining why Japanese Pokémon cards are cheaper.
New Mechanic: 2-Card “Legendary” Stadiums
The two “Legendary Summit” cards (073 & 074/076) side by side — they are played together as a single Stadium
This expansion includes 3 pairs of split Stadium cards introduced in this main set: “Legendary Trench” (071/072), “Legendary Summit” (073/074), and “Legendary Lava Cave” (075/076). Lining up the 2 cards side-by-side forms a single connected illustration. In the English version, Legendary Summit is included as 096/103 and 097/103.
To play them, you must collect both left and right halves of the same named Stadium in your hand and play them onto the field simultaneously, treating them as a single combined Stadium. You cannot play a single half onto the field as a regular Stadium. From a collection perspective, the set is complete only when both cards are paired, making it necessary to verify and collect both distinct card numbers.
Pull Rates and Box Configuration (Observed Values)
Pokémon Card pull rates are not officially published. The following are estimates compiled from secondary surveys of unboxing results by card shops and media outlets.
| Rarity | Secondary Survey Estimates |
|---|---|
| MUR | Approx. 1 in 50 to 51 Booster Boxes |
| SAR | Approx. 1 in 3 to 6 Booster Boxes |
| SR or Higher Slot (Pokémon / Supporter) | Approx. 1 per Booster Box |
| SR (Items / Tools / Special Energy) | Approx. 1 per Booster Box |
| AR | Approx. 3 per Booster Box |
| RR | Approx. 4 to 5 per Booster Box |
Depending on the survey source, estimates for SAR pull rates range from approximately 1 in 3.3 Boxes to 1 in 6 Boxes. Because figures fluctuate based on sample sizes and aggregate sources, it is not uncommon to pull no SAR from a single Box, and buyers should operate on the assumption that an MUR may not appear even across several dozen Boxes.
List Price, Market Rates, and Restock Status
The list price is ¥200 per pack and ¥6,000 per Booster Box. However, retail sales upon release centered on lotteries at places like Pokémon Center Online, making opportunities to purchase at list price in physical stores limited. As of August 3, 2026 observations on flea market apps, sealed Booster Boxes traded at market rates between ¥18,000 and ¥20,000—approximately 3 times the list price. Past expansions featuring Rayquaza on the package (Rayquaza’s Sky-High Judgment / Sky Stream) experienced high values for sealed boxes, and Storm Emeralda is viewed within the same context. As of writing, there is no official announcement regarding restock timing or availability.
If your primary target is an MUR or SAR, considering the pull rates, purchasing single cards is far more reliable and frequently keeps total expenditure lower than purchasing boxes.

Frequently Asked Questions (FAQ)
Q. Should I wait for Delta Reign?
If you play using English cards, waiting is a valid option. However, because the Japanese and English versions are distinct products with different regular card set configurations and promo allocations, you should choose the Japanese version if you want to collect specific Japanese illustrations or card numbers. For cards used in overseas official tournaments, please check the language regulations of the specific tournament you plan to join.
Q. Should I buy a Booster Box or individual packs?
If you are targeting Secret cards, buying by the Booster Box unit is the standard approach; however, acquiring boxes at list price is difficult, and flea market prices hover around 3 times the retail price. If you have a specific card in mind, purchasing single cards is the most rational choice.
Q. What are the risks of searched Booster Boxes?
Because “searching” activities exist—where individuals attempt to identify the presence of high-rarity cards from opening marks or weight—caution is required for Booster Boxes with removed shrink wrap or loose packs. Please confirm the listing explicitly states “with shrink wrap” (シュリンク付き).
Q. Why do card numbers exceed 076?
In Storm Emeralda, the regular set consists of numbers 001 to 076, while the Secret card set spans 077 to 113. Therefore, any card numbered 077 to 113 in this set is an AR, SR, SAR, or MUR. How to read rarity notations is explained in our article listing Pokémon card rarities.
