Yes — "Storm Emerald" is an early rendering of the Japanese set name "Storm Emeralda." The official English Mega Rayquaza set is called Delta Reign, releasing November 6, 2026.
Same set, different name
If you've seen "Storm Emerald" floating around, that's the Japanese set "Storm Emeralda" (M6) — an early/placeholder rendering of its name. The official English release is titled Delta Reign, and it's built from the same Mega Rayquaza ex set.
Why the confusion
English Mega Evolution sets often get a different name from their Japanese counterpart. The Japanese Storm Emeralda already released, on July 31, 2026; the English Delta Reign follows worldwide on November 6, 2026. So there's no separate "Storm Emerald" English set — it's Delta Reign.
What to search for
For English product, news and preorders, look up Delta Reign rather than Storm Emerald — that's the name on Pokémon's official materials.
