Delta Reign Chase Cards: Mega Rayquaza ex and Every Secret Rare

Delta Reign is the sixth main set of the Mega Evolution era. It releases on Friday, November 6, 2026, after prerelease events from October 24. Most of its cards come from the Japanese set Storm Emeralda, with extra cards from Japan's Mega starter decks.

Mega Rayquaza ex is the face of the set, and it gets the gold treatment. Here's what to chase, the full secret rare list, and what finishing the set will take.

Card numbers and the secret rare count come from the community set lists published before release. The Pokémon Company has only said the set has "over 135 cards", so we'll confirm the details once English cards are out.

The Delta Reign chase cards

1. Mega Rayquaza ex: Mega Hyper Rare (141/103)

The gold Mega Rayquaza ex is the card of the set. Its Japanese version is the most valuable card in Storm Emeralda. Mega Hyper Rares are the rarest pull in Mega Evolution packs, and Rayquaza has one of the biggest fan bases of any legendary. It's the card most collectors will be hoping for.

2. Mega Rayquaza ex: Special Illustration Rare (138/103)

A full illustrated scene of the set's mascot. For many collectors this is the one they want in the binder: a Special Illustration Rare shows off the artwork in a way the gold card doesn't.

3. Raikou ex: Special Illustration Rare (136/103)

The legendary beasts always draw collectors, and Raikou gets its own SIR here. It's the pick for anyone building a Raikou or legendary-beasts character binder.

4. Mega Golurk ex and Mega Golisopod ex: Special Illustration Rares (137 and 135)

Two of the newer Mega Evolutions, each in a full-art scene. New Mega forms of fan favourites often do well with collectors once English copies are out.

5. Aarune and Zinnia's Trust: Special Illustration Rares (139 and 140)

The set's supporter SIRs. Zinnia is the Hoenn character tied to Rayquaza's story, which makes Zinnia's Trust a natural partner for the mascot in a binder page.

Illustration Rares worth watching

Delta Reign has 14 Illustration Rares, and these are often the cards collectors love most. Groudon (111) is the standout, since it pairs with Rayquaza and the Kyogre promo in the Elite Trainer Box. Eevee (114) and Sprigatito (105) will be popular with character collectors.

What a Delta Reign master set involves

A master set means every card in the set plus every reverse holo. In Mega Evolution sets, the commons, uncommons, rares, Trainers and special Energy in the main set all have a reverse holo version. The ex cards (Double Rares) and the secret rares don't.

So a Delta Reign master set means roughly 141 cards plus a reverse holo for most of the 103 main-set cards. That's well over 200 cards to track. We'll confirm the exact reverse holo count once English cards are in hand.

The Elite Trainer Box promo (Kyogre) and the blister promos have their own promo numbers, so they aren't part of the set count. Many collectors still slot them in beside the set.
