Storm Emeralda: Everything You Need to Know

Storm Emeralda is the sixth set of the Japanese Mega era and one of the most anticipated displays of the summer. This guide sums up everything you need to know before buying: dates, the key cards, the new mechanic and whether a display, an ETB or single packs are worth it most.

In short: What is Storm Emeralda?

Storm Emeralda (Japanese code M6) is the sixth expansion of the Mega era in the Japanese Pokemon Trading Card Game and releases on July 31, 2026 in Japan. The Western counterpart follows on November 6, 2026 under the name Delta Reign. The set comprises 76 cards in the main set plus roughly 35 to 40 secret rares, for a total of around 115 cards. At the center stands Mega Rayquaza ex as the mascot, a Colorless Basic Pokemon with 280 HP. Alongside it come Mega Malamar ex, Mega Golisopod ex and Wishiwashi ex as well as the four Forces of Nature. The biggest new feature is the split Stadium card: one artwork that runs across two cards and is played together. For collectors and resellers the set is interesting above all because of Mega Rayquaza ex and the high number of secret rares.

When does Storm Emeralda release?

The Japan launch is July 31, 2026. The West does not get the set in its original form but as an adapted version called Delta Reign on November 6, 2026. If you want the Japanese version, you have to act early with an import retailer, because there are around three months between the JP and Western releases. During that time the Japanese version is often the only source for the new cards.

Which cards are in the set?

The set revolves around Mega Rayquaza ex: 280 HP, the ability “Champion's Roar” and the attack “Storm Emeralda” with 50x damage. Further highlights:

  • Mega Malamar ex and Sableye from the Malamar line
  • Mega Golisopod ex, a Grass-type Stage 1 Pokemon with the attack “Quatro Hold” (160 damage)
  • Wishiwashi ex as well as the Talonflame and Cacnea lines
  • the four Forces of Nature: Tornadus, Thundurus, Landorus and Enamorus

With roughly 35 to 40 secret rares, the set also contains an unusually high number of chase cards, which makes displays exciting for collectors.

What makes the split Stadium cards special?

Storm Emeralda introduces split Stadium cards. A single artwork is spread across two cards that are played together as one large Stadium card. Rules-wise they behave like a normal Stadium card, but visually they are a real eye-catcher and a collectible in their own right. It is already the second take on this idea in the Mega era.

Display, ETB or single packs: what is worth it?

A display offers the best price per pack and the highest chance at the secret rares, but is the biggest investment. An ETB is worth it if you want accessories like sleeves and dice alongside cards. Single packs are good for trying out or gifting, but most expensive per card. If you are after the chase cards, a display serves you best. More on this in our guide “Display vs. ETB vs. Bundle”.

Is Storm Emeralda worth it for collectors and resellers?

A mascot like Mega Rayquaza ex traditionally draws a lot of demand, and the high number of secret rares gives the set long-term appeal. Because the Japanese version releases three months before the Western one, there is a window in which the cards are only available through import. Acting early pays off if you want the version at launch. We will keep you posted here on availability and pricing.
