The Pokémon Company has unveiled the Delta Reign expansion for its Trading Card Game, arriving November 6 and marking the return of Mega Rayquaza to the collectible card format after an eleven-year absence. The set contains more than 135 cards spanning multiple rarity tiers, including four Mega Evolution Pokémon ex and numerous special illustration variants, along with contributions from featured artists.

Delta Reign introduces a new gameplay element called Legendary Stadiums, which pair two Stadium cards to create expanded artwork when placed side by side. Players can sample the new cards at pre-release tournaments beginning October 24, whilst digital players gain access through Pokémon TCG Live on November 5, with standard booster packs and Elite Trainer Boxes available at retail.
