The Delta Reign set is part of this broader expansion, introducing new Legendary Stadium cards and Mega Evolution Pokémon. The set is expected to be a major release for collectors and players alike, with high-value secret rares driving interest in the secondary market.

How outlets are covering it

PokéBeach and Joseph Writer Anderson both reported on the leaked secret rares, with PokéBeach focusing on the social media posts by fans and Joseph Writer Anderson providing a detailed list of the revealed cards. Wargamer.com focused on the main set list and the gameplay implications of the new cards, particularly the interactions between Groudon, Kyogre, and the new Legendary Stadium cards.
