Pokémon TCG Delta Reign Brings Mega Rayquaza ex and Two-Card Stadiums
GAME MODE Staff·Oct 18, 2026· 2m read
Prerelease events start October 24 at select Play! Pokémon stores, two weeks before the Mega Evolution expansion launches on November 6.

Mega Rayquaza ex is almost here. The Pokémon Trading Card Game’s next expansion, Mega Evolution—Delta Reign, launches on November 6, 2026, and you can play it early at Prerelease events in select Play! Pokémon Stores from October 24.
Two cards, one Stadium
Delta Reign has more than 135 cards, including over 20 Trainer cards and more than 35 cards with special illustrations. Mega Rayquaza ex leads the set, with Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex alongside it, but the standout new idea is the two-card Stadium.
Legendary Pyroduct, one of the first, needs both of its cards to be played. While it’s in play, both players’ Evolution Pokémon have no Abilities. That locks out Abilities that are popular in the current Standard format, such as Drakloak’s Recon Directive and Alakazam’s Psychic Draw.
Other early reveals include Aarune, a Supporter that finds up to three Supporter and Stadium cards in any combination, and Kecleon, whose Colorful Whip does 30 damage for each Pokémon of a different type revealed from the hand.
Inside the Build & Battle Box
Prerelease events use the Delta Reign Build & Battle Box, which contains:
- four booster packs
- a ready-to-play 40-card deck
- one of four foil promo cards: Masquerain, Magmortar, Enamorus or Kommo-o
Prerelease rules versus a normal game
| Rule | Prerelease | Usual game |
|---|---|---|
| Deck size | 40 cards | 60 cards |
| Prize cards | Four | Six |
That format keeps matches quick. Find a nearby event with the Play! Pokémon Event Locator, and if you can’t make it, you’ll be able to buy Build & Battle Boxes when the expansion launches on November 6.
