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 must both be in 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 is taken from the Japanese Storm Emeralda set and is expected to have an impact on 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 has a clear focus on Mega Evolution Pokémon ex. Mega Rayquaza ex appears 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 is likely that these Mega Evolution cards will be among the most sought-after by both collectors and players.

For collectors and players – why choose Delta Reign?

The Delta Reign booster box is a natural choice for anyone who wants a sealed product with collector value, or who wants to open and chase the latest Mega Evolution cards and split stadium cards. See the full selection of Pokémon sets for more options.
