What Are the Key Facts About Storm Emeralda (M6)?

The set is Pokémon Trading Card Game MEGA 扩展包 “Storm Emeralda”, set code M6, Japanese edition, released July 31, 2026 per the official Japanese product page. The table below lists the key facts.

Sources: pokemon-card.com M6 page for the Japanese details and the official Pokémon TCG Delta Reign page for the English set. The Japanese booster box we list is the M6 Storm Emeralda Booster Box (Japanese), which our page lists as 1 pack = 5 cards and 1 box = 30 packs, with a release date of July 31, 2026.

When Was Storm Emeralda Released?

Storm Emeralda released in Japan on July 31, 2026, a Friday. The official M6 product page gives that date, a suggested retail price of 200 yen (tax included) per pack, and 5 张/包 with cards randomly inserted.

The same page notes that Mega Rayquaza was coming to the Pokémon Pocket app on July 30, one day before the physical cards. It also advertises campaigns around the set, covered further down. Today is November 11, 2026, so the set has been out for more than three months.

If you searched for a Storm Emeralda English release date, the English set that features the same lead card, Delta Reign, released on November 6, 2026. That is 98 days after the Japanese date, counted from the two official dates.

How Many Cards Are in a Storm Emeralda Pack and Box?

A Japanese Storm Emeralda pack holds 5 cards and a booster box holds 30 packs, which gives 150 cards per box. The cards in a pack are randomly inserted, and the suggested retail price on the official page is 200 yen per pack.

The official page does not describe a Basic Energy card in each pack, so do not assume one. Our page for the regular box says the same 1 pack = 5 cards and 1 box = 30 packs. For a closer look at the box, see our guide to how many packs are in a Storm Emerald booster box and our Japanese Storm Emeralda booster box guide.

What Campaigns Come With the Storm Emeralda Release?

The Japanese M6 page lists campaigns rather than bonus promos inside a box. It names an event for the SAR-rarity Mega ex called SAR Get Battle, a sealed battle event, an at-home shield battle campaign, and a campaign built around Mega Rayquaza.

It also says Mega Rayquaza arrives in the Pokémon Pocket app on July 30. Treat these as events and campaigns advertised by the publisher, not as contents of the packs we ship. The rules and dates of each campaign are on the official M6 page.

What Does the Mega Rayquaza ex Card Do?

Mega Rayquaza ex is the lead card of Storm Emeralda, with an Ability that looks at the top four cards of your deck and an attack that scales with Fire and Lightning Energy. On the Japanese page the card is m6-058, the Ability is described as looking at the top 4 cards of the deck and attaching a basic energy when the card is benched from hand, and the attack Storm Emeralda deals more damage for each Fire and Lightning Energy on all your Pokémon.

The official English preview page for the matching English card gives more exact numbers. It lists Mega Rayquaza ex as a special illustration rare, Colorless, HP 280, illustrated by Kazuki Minami, with the Ability Ruler’s Roar and the attack Storm Emerald, which does 50 damage for each Fire Energy and each Lightning Energy attached to all your Pokémon. The preview is on the official Mega Rayquaza ex card preview.

The Japanese listings in our shop use their own numbering. The Mega Rayquaza ex SAR is number 110/076 and the MUR version is number 113/076, both in the Japanese edition. The English preview does not give a collector number or equate its special illustration rare with those Japanese numbers, so do not assume a one-to-one match.

For more on the Japanese versions of the card, see our Japanese Storm Emeralda SAR and MUR guide.

What Else Is in the Japanese Storm Emeralda Set?

The Japanese M6 page highlights other cards beyond Mega Rayquaza ex, including two pairs of Stadium cards that work as left and right halves. The stadium pairs are m6-073 with m6-074 and m6-071 with m6-072. You can run up to 4 halves in a deck, and the deck builder registers one left and one right half as a set.

A Pokémon Card Channel deck-recipe article on pokemon-card.com confirms a few cards as part of the set: the ex Pokémon whose Ability lets it be benched without evolving, That article gives no release date or rarity list, so it is a deck-building reference, not a set list.

If you want the card-by-card picture, our Rayquaza set 2026 card list for M6 Storm Emeralda and the Storm Emeralda official card facts article go through the cards in more depth than this overview. Our Storm Emeralda character cards guide covers the Pokémon individually.

Is There an English Version of Storm Emeralda?

English readers will not find a set literally called “Storm Emeralda” on the official English pages. They find Mega Evolution-Delta Reign (ME06), which features the same lead card, Mega Rayquaza ex, and released on November 6, 2026.

The Delta Reign set page lists Mega Rayquaza ex next to Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex. The Japanese page also lists a Mega Golisopod ex card (m6-009), so both lineups include Mega Golisopod ex and Mega Rayquaza ex. The official pages give no card-by-card cross-reference between M6 and ME06, so the two are linked here only by their lead card and attack name.

The names differ because the Japanese title carries a trailing “a” in Storm Emeralda, and our shop uses that spelling, while the English rendering of the official Japanese page and the English card text use Storm Emerald.

How Do Japanese M6 and English Delta Reign Compare?

The Japanese M6 pack has 5 cards and the English Delta Reign pack has 10 cards, so the two products are built differently even though they share a lead card. The table puts the official figures side by side.

On the English side, the official page says Delta Reign is Standard legal and legal for Play! Pokémon tournament play as of November 20, 2026. Our listings for this set are Japanese-edition products, so for English cards you need another seller. Our Delta Reign ETB and booster box versus Japanese Storm Emeralda article compares the two formats, and our Delta Reign pre-order guide covers US retailers.

Which Japanese Storm Emeralda Products Do We Sell?

The regular booster box page describes the product as Japanese Pokemon Card Game MEGA Storm Emeralda, condition sealed, new, release date July 31, 2026, 1 pack = 5 cards, 1 box = 30 packs, language Japanese. It also notes that if you order the box with other products, the entire order ships together; to receive other items earlier, order them separately.

The unsealed box is a separate listing with its own product page. Its page carries a product image with an Unsealed label and no written description, so check the photo before buying.

The PSA 10 singles are graded Mega Rayquaza ex cards in the Japanese edition. Our pages describe them as graded PSA 10 (Gem Mint) and note that the PSA case may have minor scratches or marks on its surface. The MUR listing shows number 113/076 and the SAR listing shows 110/076. Per our shipping policy, PSA graded cards may also be offered through our other sales channels, so an item shown online can already be sold before we lock the allocation for your order. Once your payment has cleared, we secure the PSA graded card matching your order, even if additional sourcing is required, and dispatch may take longer in that case.

How Do the Storm Emeralda Box Listings Differ?

The regular box is sealed and new, the unsealed box is a separate listing, and the two damaged-box listings are discounted for cosmetic damage to the outer box. The damaged-box pages state that one version has its factory wrap intact and the other has the factory wrap removed with the inner box still unopened.

On the damaged-box pages the photos are samples, and the item you receive may differ from them. Because both damaged-box listings are currently sold out, the regular box is the listing to look at if you want a standard sealed Japanese box. For the trade-offs between a box and a graded card, see our Storm Emeralda (M6) buying guide: booster box, PSA 10 single or damaged box.

We list several separate PSA 10 pages for the SAR 110/076 card and for the MUR 113/076 card. Each page describes the same graded card type, so pick by the product photos on the page you open.

Which Storm Emeralda Product Should You Buy?

Buy the regular booster box if you want to open Japanese packs, and buy a PSA 10 single if you want the Mega Rayquaza ex card itself. The table below matches common goals to our Japanese-edition listings.

A box gives you the pack-opening experience with randomly inserted cards. A graded single gives you a known card in a PSA case. Decide which of those you want first, then pick the listing.

How Do Shipping and Payment Work for Storm Emeralda Orders?

We ship Japanese Storm Emeralda from Tokyo with FedEx, and the stated transit estimate is usually 3-7 business days for standard shipping after dispatch. Expedited shipping through FedEx International Priority is usually 2-5 business days. Both are estimates only.

Shipping cost is calculated automatically at checkout from your delivery address. There is no minimum order amount or quantity. The shipping policy says most orders are processed and shipped within 5 business days after PayPal or Wise payment has cleared, and that this handling window is an estimate. Business days exclude weekends and Japanese national holidays. Customs processing, carrier congestion and weather can add time after handoff to FedEx, and these transit delays are outside our control. FedEx cannot deliver to P.O. Boxes, so give a physical address.

All payments are made in Japanese yen. The payment methods page lists Wise bank transfer, PayPal, and credit or debit cards through PayPal with Visa, Mastercard, American Express and JCB. PayPal and card payments carry a 5% payment processing fee; Wise bank transfer does not. PayPal Pay Later, where PayPal shows it at checkout, splits an eligible order into interest-free instalments, for example Pay in 4 in the United States and Pay in 3 in the United Kingdom. Availability is decided by PayPal.

If you are weighing a box against a graded single, the payment method matters for the total, so check the fee line at checkout before you pay.
