M6: Storm Emeralda Card List

The Hoenn weather trio, in Mega form

Storm Emeralda (M6) is the Japanese Mega Evolution set landing July 31, 2026, built around Mega Rayquaza ex and the legendary weather trio it commands. English players meet the same set as Delta Reign on November 6.

• Mega Rayquaza ex is the set mascot, joined by the newly introduced Mega Malamar ex, Mega Golisopod ex, and Mega Golurk ex.
• Introduces split 'Legendary' Stadiums: two halves (Ocean Trench, Summit, Lava Lake) that combine into a single card, echoing the HeartGold and SoulSilver LEGEND cards.
• 76 cards in the main set, with roughly 35 to 40 secret rares still to be revealed before launch, for about 115 total.
• Zinnia anchors the Trainer lineup, tying the set back to Hoenn's Delta Episode and the Rayquaza mythos.
