Overview
- The Pokémon Company confirmed on Thursday that Delta Reign will hit stores on November 6, 2026, and that prerelease tournaments at participating Play! Pokémon locations will begin on October 24.
- Official materials unveiled first-look artwork for the Elite Trainer Box and booster packs and listed the set’s card mix, including over 135 cards and counts for rarities such as 14 Illustration Rares and 17 Ultra Rares.
- Delta Reign centers on Mega Evolution ex cards and brings back Mega Rayquaza ex for the first time since 2015, alongside new Mega Golisopod ex, Mega Golurk ex, and Mega Malamar ex.
- The expansion introduces a new Legendary Stadium mechanic made from two paired Stadium cards that form extended artwork, and boosters that contain a Legendary Stadium will include both halves needed to play it.
- Reporters and retailers note likely tight supply because recent special releases sold out quickly, so collectors are being advised to watch pre-orders, third-party sellers, and the Pokémon Center for stock updates.
