A week before its Japanese release on 31 July 2026, the main set of Storm Emeralda is fully known: 76 cards, listed by PokeGuardian and Serebii. The secret rares follow after release. In English, the cards arrive on 6 November 2026 as Delta Reign.
Eight Pokémon ex
Mega Rayquaza ex has the cover. Alongside it come Mega Golurk ex, Mega Golisopod ex, Mega Malamar ex, Raikou ex, Wishiwashi ex, Talonflame ex and Heat Rotom ex. Mega Golurk ex draws the most attention: it can deal 300 damage, but only while you hold ten or more cards in hand.
Legendary Stadiums made of two cards
The set introduces three Stadium pairs – Legendary Trench, Legendary Summit and Legendary Lava Lake, two cards each. The two halves are played together from your hand and form a single Stadium, much like the two-part LEGEND cards of the HeartGold & SoulSilver era. Kyogre and Groudon, which appear here as Pokémon without a Rule Box, have attacks that lean on these Stadiums.
Trainers and other mechanics
The Supporters include Aarune, Zinnia's Trust, Tate & Liza's Training and Emcee's Hype, plus the Tool Mega Rayquaza Cap. Tornadus, Thundurus, Landorus and Enamorus share an Ability: when all four are in play, their attacks drop their Colorless Energy costs.
