Pokémon returns to the Hoenn region on November 6 with a new trading card game expansion as part of the franchise's 30th anniversary celebrations. Pokémon TCG: Mega Evolution—Delta Reign features iconic Gen 3 Legendaries including Kyogre, Groudon, and Rayquaza, which first appeared in Ruby and Sapphire.

The expansion marks Mega Rayquaza ex's return to the TCG for the first time since 2015's XY—Ancient Origins. The set also includes Mega Golurk ex, Mega Malamar ex, and Mega Golisopod ex, with more than 135 cards total.

A new Legendary Stadium mechanic allows players to combine two Stadium cards into a single connected illustration. The expansion contains three Legendary Stadiums, 14 illustration rare cards, and six special illustration rare Pokémon and Supporter cards.

Starting November 6, customers who spend $15 or more on Pokémon TCG products at participating retailers will receive promo cards. In the US, Kyogre goes to Hot Topic, Barnes & Noble, Five Below, and Macy's. Groudon is exclusive to GameStop and Giratina to Best Buy. All three promo cards feature the Pokémon 30 "What's Your Favorite?" anniversary stamp. The promotion runs at select retailers in Canada and Australia while supplies last.

Pokémon TCG: Mega Evolution—Delta Reign launches November 6, 2026, with booster packs and Elite Trainer Boxes available at participating retailers. The expansion arrives digitally on Pokémon TCG Live on November 5.
