Storm Emeralda: Japan's Next Pokemon Set Lands July 31, Led by Mega Rayquaza ex

Japan's next Pokemon set, Storm Emeralda, launches July 31 with Mega Rayquaza ex on the pack art, and English players will meet the same cards as Delta Reign on November 6. That gap is the whole story, for three months Japan holds the future of the next English chase list, and the last time that happened we watched Japanese prices predict the English market almost card for card. Here is what is revealed, why Rayquaza changes the stakes, and what to watch on launch day.

What Is Storm Emeralda?

Storm Emeralda is Japan's sixth Mega Evolution era set, and the reveals so far sketch its shape:

• Releases in Japan on July 31, 2026, with 76 cards in the main set plus roughly 35 to 40 secret rares, around 115 cards in total.
• Mega Rayquaza ex is the mascot, a Colorless Basic with 280 HP and the Champion's Roar Ability, and the early reveals include Mega Malamar ex, the Talonflame line, and a run of Zinnia-themed Trainer cards, a nod to Rayquaza's lore.
• A new mechanic debuts, a split Stadium card, the first of its kind in the game.
• The English version is confirmed: Delta Reign, November 6, 2026, the name referencing Mega Rayquaza's delta motif. For English collectors the calendar runs 30th Celebration first on September 16, our 30th Celebration hub tracks that set, then Delta Reign closes the year.

The Rayquaza Factor

Set mascots matter, and this one matters more than most. Rayquaza is one of the heaviest chase characters in the entire hobby, and the precedent is concrete, the Rayquaza VMAX alternate art from Evolving Skies trades around $1,027 raw and roughly $1,500 to $2,000 in PSA 10, the second most valuable card of the most collected modern set ever printed, behind only the Moonbreon.

That history is why the hobby watches this launch. A Mega Rayquaza ex Special Illustration Rare would instantly be a candidate for the most hunted card of the fall, in two languages. To be clear about what we do not know, the SIR lineup and pull structure are not fully revealed, and no prices exist until packs open, we do not speculate on cards nobody has pulled. What we know is the character's track record, and it is the strongest in the modern game outside Charizard and Umbreon.

Japan Goes First, and Japan Predicts

This is the third time this year the pattern runs, and we documented the last one in real time. Japan's Abyss Eye launched in May, its gold Mega Darkrai settled around $600 and the Special Illustration Rare around $400, and when the English version arrived as Pitch Black in July, the Japanese signals had called the chase list almost exactly, our Pitch Black chase cards coverage tracked it from preview to launch.

Two lessons from that run apply directly. Japanese launch prices are a preview of demand, not a promise, Abyss Eye prices cooled 15 to 27 percent after launch as supply arrived. And the ranked order matters more than the absolute numbers, what tops the Japanese chase list has topped the English one all era, the full era picture is in our Mega Evolution chase cards guide. For why Japanese cards themselves are a market worth understanding, print quality, pull rates, and all, see our are Japanese Pokemon cards worth more guide.

What Happens on July 31

• The full set list and secret rares go public as Japanese collectors rip the first boxes, including whatever Rayquaza chase tops the rarity ladder.
• The first real prices print within days, and we will publish the ranked Storm Emeralda top list as soon as the sold data exists, the same JP-first coverage that called Pitch Black.
• For English collectors, this is a watching week, not a buying panic. Delta Reign is three months out with the 30th Celebration in between, and the Abyss Eye lesson says early Japanese prices run hot before cooling. Watch the ranked order, note the chases, and let the market settle.

Frequently Asked Questions

When does Storm Emeralda release?

Storm Emeralda releases in Japan on July 31, 2026, as the sixth Japanese set of the Mega Evolution era, with 76 main-set cards plus roughly 35 to 40 secret rares. The English version, Delta Reign, releases worldwide on November 6, 2026, after the 30th Celebration anniversary set arrives on September 16.

What is the English version of Storm Emeralda?

Delta Reign, confirmed for November 6, 2026. The English name references Mega Rayquaza's delta design motif. The card pool carries over from the Japanese set, which is why Japanese launch prices in August will preview the English chase list months early, the same pattern Abyss Eye ran before it became Pitch Black.

What are the Storm Emeralda chase cards?

The revealed headliners are Mega Rayquaza ex, Mega Malamar ex, and the Zinnia-themed Trainer cards, but the secret-rare lineup is not fully revealed and no prices exist until the set launches. Rayquaza's track record is the signal, his Evolving Skies alternate art trades around $1,027 raw, so a Mega Rayquaza Special Illustration Rare would be a candidate for the most hunted card of the fall. We will rank the real chase list when Japanese sold data exists.

Where to Go From Here

Storm Emeralda is nine days out, the reveals point at a Rayquaza-sized autumn, and the Japanese launch will hand English collectors a three-month preview of Delta Reign's chase list. We will be back with the ranked top when the first prices print. Until then, if the era has you opening rather than waiting, the Polkastarter marketplace runs packs that list every card, value, and chance before you open, with a free Lootbox when you sign up.
