Pokémon TCG Mega Evolution—Delta Reign Revealed With Mega Rayquaza ex and New Legendary Stadium Cards

The Pokémon Company International has officially revealed new details for Pokémon TCG: Mega Evolution—Delta Reign, the next expansion in the Mega Evolution Series, which is scheduled to arrive at participating retailers worldwide beginning November 6, 2026.

Mega Rayquaza ex leads the new set, joined by Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex. In total, Pokémon says Delta Reign will include four Mega Evolution Pokémon ex along with six additional Pokémon ex.

For collectors, the expansion will include a substantial lineup of higher-rarity cards. Pokémon has confirmed 14 illustration rare Pokémon cards, 17 ultra rare Pokémon and Trainer cards, and six special illustration rare Pokémon and Supporter cards.

One of the more unusual additions to Delta Reign is a new type of Stadium card. The expansion will contain six Stadium cards that can be paired together to form three different Legendary Stadiums. Two corresponding cards are needed to create each complete Legendary Stadium, giving collectors another group of connected cards to assemble within the set.

Delta Reign will be released through a range of familiar Pokémon TCG products. The product lineup includes booster packs, Elite Trainer Boxes, and various collections at participating retailers worldwide.

The Elite Trainer Box also puts Kyogre in the spotlight with a promotional card included with the product. A Pokémon Center version of the Elite Trainer Box will also be offered through Pokémon Center.

The arrival of Mega Rayquaza ex is likely to make Delta Reign an especially closely watched release among Pokémon card collectors, but the newly announced rarity lineup gives the set considerably more to chase beyond its featured Legendary Pokémon. The illustration rares, special illustration rares and connected Legendary Stadium cards provide multiple collecting angles for anyone looking to build out the complete expansion.
