Storm Emeralda Leaks (M6): What Is Now Officially Confirmed

Storm Emeralda (M6), the Japanese edition of the Pokémon Card Game MEGA expansion pack “ストームエメラルダ”, has a release date of July 31, 2026 on the official Pokémon Card site, which also lists its featured cards, led by Mega Rayquaza ex. This guide sticks to what official pages and our own listings say.

Updated November 5, 2026

What are the key facts about Storm Emeralda (M6)?

Storm Emeralda is the Japanese MEGA expansion pack with set code M6, a July 31, 2026 release date, and 5 张/包. The table below gives the short version, and each row links the page it comes from.

Two terms matter for the rest of this guide. “Japanese edition” means the Japanese-language product sold in Japan. “Official” means a page on pokemon-card.com or pokemon.com, or a product listing on our own site. Anything outside those pages is not used here.

What does “Storm Emeralda leaks” mean, and what do official pages say now?

For the Japanese set, the official M6 page now lists featured cards by name. This page repeats no unofficial claim, because we cannot tie one to an official source.

What we can do is list what Pokémon’s own pages say, and mark where they stay silent. If a detail is not in the sources linked on this page, treat it as unconfirmed.

Two limits of the official Japanese page are worth knowing before you read on:

• It does not list rarities. A statement about how many SARs or other rarities the set has cannot be sourced to it.
• It shows featured cards, not a full card list. The complete list is not something the page provides.

Our own listings do give card numbers and rarities for two Mega Rayquaza ex cards, which we cover further down. For a broader look at the whole set, see our Delta Reign card list, which maps confirmed cards to Japanese M6 prints.

What did Pokémon officially state about the M6 release?

The official page gives a release date of July 31, 2026, a suggested retail price of 200 yen (tax included) and 5 张/包. These details are on the official M6 page.

The same page adds several notes that collectors often miss:

• Cards are randomly inserted in packs.
• Basic Energy cards are not included in this expansion pack.
• Two-part stadiums (a left half and a right half) may be included up to 4 in total, and the deck tool registers them as one left and one right per set.
• Sealed battle (シールド戦) is a format in which players open unopened packs and build a deck on the spot.
• メガエルレイドex (Mega Gallade ex) is shown as a prize card (SAR) in the sealed battle campaigns.
• A campaign called 「宙駆けるメガレックウザ」 is listed, and the page states that Mega Rayquaza comes to Pokémon TCG Pocket (ポケポケ) on July 30 (Thursday).

The page states these items separately and does not explain how they relate to each other, so we do not add an interpretation.

Which cards are officially featured in Storm Emeralda?

The official page names Mega Rayquaza ex first among its featured cards, followed by stadiums, a Pokémon tool and several other cards. The table lists each name with the details the page gives; where the page gives only a name, we say so.

Source for every row: pokemon-card.com/ex/m6. This is a featured selection, not the full card list. Our site has separate articles for other angles: see the Storm Emeralda chase cards guide and the Storm Emeralda booster box guide.

What does the Mega Rayquaza ex card do?

The Japanese Mega Rayquaza ex has the Ability はしゃのほうこう and the attack ストームエメラルダ, and the English preview describes a card with the Ability Ruler’s Roar and the attack Storm Emerald. The English page does not name Storm Emeralda, so any link between the two is an inference from the Mega Rayquaza ex name and the attack name.

The English preview on Pokémon.com gives these details for the English card:

• Card number 138 (ME06 EN 138), a special illustration rare.
• Artist: Kazuki Minami, described as the grand prize winner of the Pokémon TCG Illustration Contest 2024.
• Colorless type, 280 HP.
• Ability Ruler’s Roar: when played from your hand to your Bench, look at the top four cards of your deck and attach a Basic Energy to Mega Rayquaza ex.
• Attack Storm Emerald: 50 damage for each Fire Energy and each Lightning Energy attached to all your Pokémon.

The English article also says the set contains a variety of powerful new Mega Evolution Pokémon ex, but it does not list them, so we do not either. The official Japanese page lists the Japanese Mega Rayquaza ex’s ability and attack by name only, without the effect text, so the English wording above should not be read back onto the Japanese card.

Which Mega Rayquaza ex cards do we list for Storm Emeralda?

We list two Mega Rayquaza ex cards from Storm Emeralda: the SAR, numbered 110/076, and the MUR, numbered 113/076. Both are PSA 10 (Gem Mint) graded listings from the “Storm Emeralda” expansion pack (M6). These are the two our catalog shows; we do not claim they are the only prints.

Two further listings exist for the same cards: the SAR (second listing) and the MUR (second listing). Product pages show the current status of each one, so check the page before you decide.

Our MUR listing carries the name “MEGA Rayquaza ex MUR No. 113/076” and no separate rarity line. The SAR listing says “Rarity: SAR”. Both product pages note that the PSA case may have minor scratches or marks on its surface, and that stock levels can change, so an order may take a little longer to ship.

For other prints in the set, including the Raikou ex prints, read our Raikou ex SAR and SR guide and the Japanese Storm Emeralda SAR and MUR list.

What do the official deck recipes show about the set?

The official deck article shows three deck recipes built with Storm Emeralda cards, two of them around Mega Rayquaza ex and Mega Golisopod ex (メガグソクムシャex). It is titled 拡張パック「ストームエメラルダ」のカードを使ったデッキレシピを公開！ and is hosted on pokemon-card.com. The page does not state a publication date; the image path suggests July 2026.

Deck 1 is the one that ties directly to the lead card: it names Mega Rayquaza ex, ファイアローex and ぼうけんのランタン, and the page says it aims for over 350 damage with ストームエメラルダ. Deck 2 is built around Mega Golisopod ex, and the page says that card needs only one energy for its attack. Deck 3 is listed on the page, but we have no further detail on it, so we say no more.

The page is a good example of how to read official material: it names cards and attacks, and it states the damage goal for one deck. We add no claim beyond what our source notes record. The Deck 1 and Deck 2 cards also appear in the featured table above, which lets you cross-check names between the two official pages.

How does Japanese M6 relate to English Delta Reign?

The English counterpart appears to be Pokémon TCG: Mega Evolution—Delta Reign, and an article on Pokémon.com dated October 30, 2026 says the set arrives on November 6, 2026. The word “appears” is deliberate: the page does not say “Storm Emeralda”, so the link is inferred from the Mega Rayquaza ex and its Storm Emerald attack.

Do not treat card numbers as interchangeable. A Japanese number like 110/076 and an English number like 138 are different numbers, and the sources do not say that a Japanese print and an English print share the same artwork. For the pre-order angle, see Delta Reign pre-orders: US retailers vs Japan M6 box and the ETB and box comparison.

What is inside the Storm Emeralda booster box?

A Japanese Storm Emeralda booster box holds 30 packs, and each pack has 5 cards, which is 150 cards per box by simple multiplication. Those numbers come from our M6 booster box listing, which also gives the release date of July 31, 2026, the condition “Sealed New” and the language, Japanese.

The listing says sealed and wrap-removed options are available for the regular box. Separately, we have listed two damaged-box versions: one with the factory wrap intact, and one with the wrap removed. The wrapped page says the box is unopened and still in its original wrap, and that the cards inside are unaffected. The wrap-removed page says the inner box remains unopened and the contents are factory-original. Both pages say the discount is for cosmetic damage to the outer box (such as dents or scratches), that the photos are samples, that the item is sold as-is, and that returns and refunds are not accepted.

The damaged-box pages explain why these boxes exist: our warehouse in Tokyo buys large volumes of Japanese trading cards, some boxes arrive with dents or scratches, and those that cannot be sold as mint-condition products are separated during inspection and offered at a lower price. The pages also note that the condition photos are samples and that the box you receive may differ from them.

How can you check a Storm Emeralda claim yourself?

Compare the claim with the official M6 page, the official deck article and the Pokémon.com preview, then note what those pages do not say. The checks below use only facts stated earlier in this guide.

1. Is the card named on the official M6 page? The page features the cards in the table above by name. If a card is not among them, the page does not tell you anything about it either way.
2. Does the claim include a rarity? The official M6 page does not list rarities, apart from showing メガエルレイドex as a prize card (SAR) in the sealed battle campaigns. Other rarity claims need another source, such as a product listing that shows the number and rarity.
3. Is a Japanese number being used for an English card, or the reverse? Our listings show Mega Rayquaza ex as 110/076 and 113/076. The English preview shows 138 (ME06 EN 138). They are different numbers.
4. Is the English set being called Storm Emeralda? The Pokémon.com preview does not use that name. The link to Delta Reign is an inference.
5. Is a value forecast attached? No source in this article supports one, and we make none.

The Pokémon.com preview gives the Mega Rayquaza ex details quoted above, a count of over 135 cards, and a general statement that the set has a variety of powerful new Mega Evolution Pokémon ex. It does not name the other cards. Our pages on the Build & Battle Box and the Pokémon Center Online lottery cover related news.

How does shipping work for Storm Emeralda orders?

We ship by FedEx: Standard (FedEx International Connect Plus) usually takes 3-7 business days after dispatch and Expedited (FedEx International Priority) usually 2-5 business days. Both are estimates only, and the cost is calculated at checkout from your delivery address. These details are in our shipping policy, last updated September 8, 2026.

The policy also says that delivery dates shown on our website, at checkout or in carrier tools are estimates only. They do not include handling time, pre-order release timing, supplier allocation delays, quality inspection holds, weekends, Japanese national holidays, customs processing, carrier congestion, weather or destination-country conditions. Business days exclude weekends and Japanese national holidays.

If dispatch is delayed, the policy says we will contact you by email as soon as practical with the revised estimate, and for significant delays before handoff to FedEx we may offer the option to wait or to cancel with a full refund. Once an order is dispatched, you can check the tracking number and the carrier’s latest delivery estimate from your account or shipping confirmation email.

For PSA graded cards such as the Mega Rayquaza ex listings above, the policy adds that PSA cards may also be offered through our other sales channels. A PSA item shown online may already be sold before the allocation is locked for your online order. Once payment has cleared, we will secure the PSA graded card matching your order, even if additional sourcing is required, and dispatch may take longer in that case.

Before you order, check the address carefully. The policy says the customer is responsible for a complete and accurate shipping address. While an order is paid and its shipment has not yet been scheduled, you can update the shipping address yourself from My Account > Orders. The destination country cannot be changed, and the carrier, shipping method and FedEx service level stay as selected at checkout.

How do payments work for Storm Emeralda orders?

All payments are made in Japanese yen, and Wise bank transfer is the only method without the 5% payment processing fee. This is stated on our payment methods page, last updated November 5, 2026.

The Wise deadlines are specific. Without a screenshot, your order is cancelled automatically if payment has not been received within 12 hours of placing it, or within 3 hours if the order contains a pre-order item. With a screenshot, you upload it within 5 days of placing the order, and the order price is then held for a total of 10 days. The screenshot option requires an account and is not available at guest checkout. Enter the payment reference issued with your order, SST-{order number}, exactly as issued.

If you pay by SWIFT, the page says a receiving fee of JPY 611 is deducted before the funds reach us, so you should add JPY 611 to your order total. It also advises selecting the OUR charge option so that correspondent bank fees are covered on your side. If the amount received is short, order processing is paused until the shortfall is paid and confirmed.

For card payments, the card form opens in PayPal’s own secure window. We never see, receive or store card details, and a PayPal account is usually not required for a card payment. Your card issuer may apply 3-D Secure authentication, a step handled between PayPal and your issuer.

The page lists the interest-free PayPal Pay Later options seen at our checkout: United States and Canada, PayPal Pay in 4 (4 payments, one every 2 weeks); United Kingdom, PayPal Pay in 3 (3 monthly payments); France, PayPal Paiement en 4X (4 monthly payments); Italy, PayPal Paga in 3 rate (3 monthly payments); Spain, PayPal Paga en 3 plazos (3 monthly payments); Australia, PayPal Pay in 4 (4 fortnightly payments). In other countries PayPal may show a different option on different terms, and the terms PayPal displays are the ones that apply.
