The Pokemon Company International announced a new Pokemon TCG expansion called Mega Evolution Delta Reign that features multiple new ex versions of characters like Mega Rayquaza ex. It will also feature the two-card Legendary Stadium cards. It will launch on November 6, 2026. Both booster packs and an Elite Trainer Box are confirmed. However, there will be pre-release tournaments featuring the new cards starting on October 24, 2026, and the cards will be in Pokemon TCG Live starting on November 5, 2026. This follows the October 2025 Mega Evolutions expansion.
The announcement included an overview of what to expect from the set and how many cards will be included. There will be over 135 total. Of those, six will be Legendary Stadium cards that can be played as pairs to create three new Stadiums. (If you get a pack with them, you will get both cards needed to make the Stadium in it.) In terms of ex cards in this Pokemon TCG expansion, there will be three other Mega Evolution ones in addition to Rayquaza and six standard ones. There will also be some special and rare illustration Pokemon and Supporter cards, with 20 total. 17 “ultra rare” Pokemon and Trainer cards will be present as well.
Here’s how the booster packs and Elite Trainer Box will look for this expansion:
