The Pokemon Company has revealed the next expansion for the Pokemon Trading Card Game. Dubbed Astral Radiance, the upcoming Sword & Shield expansion releases in May and hones in on the recently released Switch game Pokemon Legends: Arceus.

The Astral Radiance expansion includes cards for various Hisuian forms introduced in Legends Arceus, including Decidueye, Typhlosion, and Samurott. Card backgrounds will also feature artwork inspired by Legends Arceus and the Hisui region.

The set also introduces a new gameplay mechanic and card type called Radiant Pokemon. According to the Astral Radiance press release, Radiant Pokemon cards have “a powerful Ability or attack with the potential to impact the Pokémon TCG metagame.” Radiant Pokemon cards will also feature “Shiny Pokémon illustrated in etched artwork” for the key art. The expansion will have three Radiant Pokemon in the full set. As per the new rules, players can only run one Radiant Pokemon in a deck, but these new cards could add an interesting wrinkle to matches.
