Delta Reign Booster Packs

Delta Reign is the sixth main expansion of cards for the Mega Evolution Series of the Pokémon Trading Card Game, featuring Mega Rayquaza ex as the central Pokémon. In addition to introducing more Mega Evolution Pokémon ex to the game, Delta Reign also introduces "Legendary Stadiums", which are Stadium cards that are played together as a pair. Legendary Stadiums have combined illustrations between the pair of cards that form them. Any Delta Reign booster pack containing a Legendary Stadium will contain both halves of each pair.^[1]

Delta Reign is expected to include cards released in the Japanese Storm Emeralda expansion. Delta Reign features more than 135 cards,^[2] including four Mega Evolution Pokémon ex, six Pokémon ex, six Stadium cards creating three Legendary Stadiums, 14 illustration rare Pokémon, 17 ultra rare Pokémon and Trainer cards, and six special illustration rare Pokémon and Supporter cards.^[1] Delta Reign will be released worldwide on November 6, 2026.^[1]

Delta Reign was first revealed on June 18, 2026, at the same time as Storm Emeralda and Ruler of the Skies, the latter being a Rayquaza-themed set for Pokémon Trading Card Game Pocket.

-------------------------------

The Delta Reign set will include:

• Over 135 cards
• Four new Mega Evolution Pokemon ex, including Mega Rayquaza, Golurk, Malamar, and Golisopod
• Six Pokemon ex
• More than a dozen Trainer cards, including three new Legendary Stadiums
• 14 illustration rare Pokemon
• 17 ultra rare Pokemon and Trainer cards
• Six special illustration rare Pokemon and Supporter cards

The set will introduce new split Stadium cards, each with "Legendary" in their names. These obviously hearken back to the LEGEND cards of the HeartGold & SoulSilver era, like Lugia LEGEND, where you needed both halves of the card to play it. Because both halves share the same name, you can only ever play two sets of the card in a deck.
