Delta Reign is here. Here's what matters.

Mega Rayquaza ex headlines the latest English Pokémon TCG expansion. The November 6 release adds new Mega Evolution Pokémon ex, a two-card Stadium mechanic, and more than 135 cards to collect.

Mega Rayquaza takes the spotlight

Pokémon TCG: Mega Evolution—Delta Reign launched on November 6, 2026. Mega Rayquaza ex returns alongside Mega Golurk ex, Mega Malamar ex, and Mega Golisopod ex. The expansion also features more than 35 Pokémon and Trainer cards with special illustrations. For collectors, that means the set is about more than its headline Mega Evolution cards: the illustration lineup is worth exploring before deciding which pages to build.

Legendary Stadiums bring something different

The expansion introduces Legendary Stadiums, a mechanic built around two Stadium cards that form a connected piece of artwork when placed together. Pokémon says a booster pack containing a Legendary Stadium includes both halves. It is an unusual visual pairing that could make a compelling two-card display—but the individual cards and their identifiers should still be recorded accurately.

Which products are available?

The Booster Display Box contains 36 packs; the Booster Bundle has six. The standard Elite Trainer Box includes nine packs and a Kyogre full-art foil promo. The Pokémon Center Elite Trainer Box increases that to 11 packs and includes two Kyogre promos, one carrying the Pokémon Center logo.

There is also a Build & Battle Box with a 40-card ready-to-play deck, four packs, and one of four foil promo cards. Check the exact product and retailer for its availability; accessory contents and promotion periods differ between releases.

Promo cards are their own collecting decision

Pokémon also announced gift-with-purchase promos for Kyogre, Groudon, and Giratina at participating retailers, while supplies last. Those branded or stamped promotional versions should not be cataloged as ordinary set printings simply because the Pokémon or artwork looks familiar. In Ninefoil, keep the exact variant separate.

A better way to start collecting the set

Browse Delta Reign in Collection → Browse sets to inspect indexed printings, then distinguish owned cards from your wishlist and cards you have not tracked. The set index is a starting point, not a guarantee that every possible stamped, reverse-holo, or promotional variation appears as a separate row. Check the set, number, language, and artwork before adding anything to your binder.
