Delta Reign (ME06) is the sixth Mega Evolution set, releasing November 6, 2026, headlined by the return of Mega Rayquaza ex. Its Japanese predecessor, Storm Emeralda, is already out and points to three more Megas plus a new split-Stadium mechanic.
The Mega Rayquaza set
Delta Reign is the sixth main Mega Evolution Series expansion (ME06), built around the return of Mega Rayquaza ex — one of the most popular Pokémon in the game. The theme leans on Hoenn and the Delta Episode, hence the name.
What's confirmed so far
Delta Reign's Japanese predecessor, Storm Emeralda, released in Japan on July 31, 2026, and its full card list is public. Bulbapedia describes those cards as "expected to be included" in the English Delta Reign, though Pokémon hasn't confirmed an exact match. On that basis, Delta Reign looks set to add three more Mega ex alongside Mega Rayquaza ex — Mega Golisopod ex, Mega Golurk ex and Mega Malamar ex — plus a new split Stadium mechanic, where two Stadium cards are played together as one. English-specific card count, products and pricing are still to be announced.
The Pocket tie-in
Delta Reign launches alongside the Pokémon TCG Pocket set "Ruler of the Skies" on the same November 6 date — a first for the franchise, and a sign of how central Mega Rayquaza is to the release.
