Storm Emeralda (M6) Card List: Japanese Mega Rayquaza ex Set Guide

Storm Emeralda (Japanese set code M6) is the next Japanese Pokémon TCG expansion, headlined by Mega Rayquaza ex and launching in Japan on July 31, 2026 — more than three months before its English counterpart. This is our running guide to what’s in the set: confirmed cards, chase cards, the new split-Stadium mechanic, and how overseas collectors can get it first.

What is Storm Emeralda (M6)?

Storm Emeralda is a main-series Japanese expansion in the Mega Evolution era, built around Mega Rayquaza ex — the fan-favorite Dragon-type returning to the spotlight for the first time in years. The set name plays on the Hoenn region (the “Emerald” era), and much of the confirmed lineup — Rayquaza, the Trainer Zinnia, Sableye, and the Cacnea line — leans into that Hoenn theme, mixed with the Forces of Nature and a handful of new Mega Evolutions.

Japanese now, English “Delta Reign” in November

The single most important thing for overseas collectors: Storm Emeralda is Japan-first. The Japanese M6 set drops on July 31, 2026, while its English-language equivalent — released as Delta Reign in the Mega Evolution series — isn’t due until November 6, 2026.

That’s a gap of more than three months. For collectors chasing Mega Rayquaza ex, Zinnia cards, or the new Forces of Nature, the Japanese printing is the only way to hold these cards in 2026’s summer rather than waiting for the winter English drop. Japanese cards are also widely regarded for consistent print quality and centering — a reason many graders prefer the Japanese originals even after the English set arrives. That Japan-first dynamic is also what’s behind price gaps like the one we track on Mega Lucario ex SAR — same artwork, about 42% of the English price — and if grading is part of your plan, our PSA grading guide covers what to check before submitting.

Why collectors are already watching this set

We sell Japanese single cards to collectors worldwide, and we track — anonymously and in aggregate, never at the level of individual customers — what people search for and view in our store. Storm Emeralda’s headliners are already showing up in that data, weeks before release.

• ”Rayquaza” searches jumped +175%. Over the last 30 days (Jun 22 – Jul 21, 2026), searches for “rayquaza” in our store rose to 33, up from 12 in the prior 30 days — and they spiked in the week of July 13, exactly as Mega Rayquaza ex reveals spread.
• The Forces of Nature are moving. Even before the set lands, existing Tornadus and Enamorus Art Rare cards from other sets saw rising product-page views in our store (Tornadus AR: 0 → 7; Enamorus AR: 5 → 7 over the same window) — all four are confirmed for Storm Emeralda.
• Talonflame has a steady following. Our Talonflame Art Rare listing has held some of the most consistent views of any card in this group — and Talonflame ex is a confirmed Storm Emeralda card.

In other words, the demand isn’t hype we’re inventing: it’s showing up in what real collectors search and click on our own site. (Dark-type Mega chase cards have been running hot too — see our Mega Darkrai ex SAR price watch.)

Revealed cards so far

Below is every Storm Emeralda card confirmed as of July 21, 2026, grouped by type, with a short note on what each does. English card names are our provisional translations until the English Delta Reign release confirms official names.

Mega Evolution ex

Card	Notes
Mega Rayquaza ex	Set mascot. Ability “Sovereign Roar” — when played from hand to bench, look at the top 4 of your deck and attach a Basic Energy. Attack “Storm Emeralda”: 50× the Fire + Lightning Energy on all your benched Pokémon.

Stadiums — “Legend” split cards

Card	Effect
Legendary Trench	Combine two of them as one Stadium — all Pokémon heal double.
Legendary Summit	Combine two of them as one Stadium — when your Colorless Pokémon are KO’d, the opponent takes 1 fewer Prize.

Chase cards & rarities

Storm Emeralda’s full rarity breakdown isn’t official yet, but based on the reveals and how past Rayquaza sets were built, here’s where attention is pointing (treat pre-release rarities as expectations, not confirmed):

• Mega Rayquaza ex — MUR (top chase). Following the recent pattern where the set mascot gets the highest “Mega Ultra Rare” treatment, Mega Rayquaza ex is expected to be the headline pull, reportedly at around one per carton. Its full-art illustration is the single most-anticipated reveal of the set.
• Mega Rayquaza ex — SAR. A Special Art Rare version is expected alongside the MUR.
• Zinnia SAR. “Zinnia’s Faith” continues the Rayquaza-and-Zinnia pairing from the Sky Stream era; Zinnia Trainer cards have been chase-tier before and a SAR is widely expected here.
• ex SAR/SR versions of Mega Golisopod ex, Mega Malamar ex, Wishiwashi ex and Talonflame ex are the usual secondary chases.

The new “Legend” split-Stadium mechanic

Storm Emeralda introduces one of the era’s most talked-about design ideas: split Stadium cards. Legendary Trench and Legendary Summit can’t be played on their own — you combine two matching halves from your hand to put a single Stadium into play. It’s a genuinely new deckbuilding wrinkle, and part of why this set is drawing interest beyond just the Rayquaza chase.

How overseas collectors can get it first

Because the set is Japan-first, the practical question for most collectors is simple: get the Japanese cards now, or wait for the English Delta Reign in November? A few things worth weighing:

• Timing. Japanese singles are available from launch (July 31, 2026); the English versions are more than three months out.
• Print quality. Japanese printings have a strong reputation for centering and surface consistency — a factor if you’re buying with grading in mind (our Japanese vs English comparison covers why).
• Singles vs sealed. If you want one specific card (say, a clean Mega Rayquaza ex or the four Forces of Nature), buying the single you want is usually more predictable than chasing it through sealed packs.

FAQ

When does Storm Emeralda release?

The Japanese M6 set releases on July 31, 2026. Its English-language equivalent, Delta Reign, is scheduled for November 6, 2026.

Is Storm Emeralda the same as Delta Reign?

They’re the same expansion for different regions: Storm Emeralda is the Japanese M6 set (July 2026), and Delta Reign is the English release in the Mega Evolution series (November 2026). Card artwork and contents overlap heavily; the Japanese version simply arrives first.

What is the chase card in Storm Emeralda?

Mega Rayquaza ex is the set mascot and expected top pull, with a MUR (“Mega Ultra Rare”) version reportedly at around one per carton, plus a Special Art Rare (SAR). A Zinnia SAR is also widely anticipated. Rarities are pre-release expectations until officially confirmed.

How many cards are in the set?

The main set is expected to be around 76 cards, with an additional 35–40 secret rares, for a rough total near 115. About 25 cards are confirmed as of July 21, 2026 — we update this page as more are revealed.

Is Mega Gallade ex in Storm Emeralda?

In Japan, the Mega Gallade ex SAR is an event-distribution promo (the “Get Battle” event running July–August 2026), not a card pulled from Storm Emeralda packs.

Why buy the Japanese version instead of waiting for English?

Two reasons: timing (the Japanese cards are available more than three months earlier) and print quality (Japanese printings are known for consistent centering and surfaces, which matters for grading). If you want a specific card, buying the Japanese single is often the most direct route.
