New mechanics: Split stadium in Delta Reign

Delta Reign introduces the split stadium mechanic to the English Pokémon TCG. Split stadium cards consist of two halves that both must be in your hand and played at the same time. Each half has its own effect—often one for each player—and both effects are active simultaneously. The mechanic comes from the Japanese Storm Emeralda set and is expected to influence deck building and gameplay.

Mega Evolution and the hunt for Mega Rayquaza ex

As the sixth main expansion in the Mega Evolution series, Delta Reign clearly focuses on Mega Evolution Pokémon ex. Mega Rayquaza ex stands out as the set’s flagship chase card, and several Mega Pokémon—including Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex—are central to the expansion. While the full English card list has not yet been released, it’s likely these Mega Evolution cards will be among the most sought-after by collectors and players alike.

For collectors and players – why choose Delta Reign?

Delta Reign booster box is an excellent choice if you want a sealed product with collector value or if you plan to open it and chase the latest Mega Evolution cards and split stadium cards. See the full selection of Pokémon sets for more options.
