Delta Reign: Everything You Need to Know

Delta Reign (German Delta-Herrschaft) releases on 6 November 2026. It is the Western version of the Japanese set Storm Emeralda, led by Mega Rayquaza ex. Here is everything you need to know before release: dates, products, prices, the key cards and the new card type.

Quick answer: What do you need to know about Delta Reign?

Delta Reign is the sixth main expansion of the Mega series and releases on 6 November 2026, with the Build & Battle Box arriving early on 24 October. The set has more than 135 cards: 103 regular cards plus secret rares, including 14 Illustration Rares, 17 Ultra Rares and 6 Special Illustration Rares. It takes almost all 113 cards of the Japanese set Storm Emeralda and most of the new cards from the Japanese Mega Starter Set ex decks. Four Mega Pokémon ex lead the set: Mega Rayquaza ex, Mega Golurk ex, Mega Malamar ex and Mega Golisopod ex. New are the split Stadium cards, which consist of two halves and can only be played together. A booster pack contains 10 cards, 3 of them holographic. At Pokémon Center Germany, the Elite Trainer Box costs €61.99 and a booster display €165.99, both as pre-orders. The top of the confirmed secret rares so far is the Special Illustration Rare Raikou ex 136/103.

When does Delta Reign release?

The official release is on Friday, 6 November 2026. From then on, booster packs, displays, Elite Trainer Box, Booster Bundle and blisters are in stores. The exception is the Build & Battle Box: it releases two weeks earlier, on 24 October 2026, so prerelease tournaments can be played with the new set.

The Japanese original Storm Emeralda already released on 31 July 2026. Delta Reign arrives a good three months later, but directly in German.

Which products are there?

• Booster pack: 10 cards, 3 of them holographic and at least one rare. There are four booster designs, one per Mega Pokémon ex.

How much does Delta Reign cost?

Pre-orders are open at Pokémon Center Germany. There, the Elite Trainer Box costs €61.99 and a booster display €165.99, each plus shipping. With the Elite Trainer Box you pay €6.89 per booster on paper, and the Kyogre promo and accessories come on top. The Elite Trainer Box was already sold out at Pokémon Center at one point. Other retailers set their own prices, which often rise around release.

Which cards are the highlights?

Rayquaza returns in its Mega form for the first time since the XY series. The four Mega Pokémon ex at a glance:

• Mega Rayquaza ex 084/103: When you play it, its Ability attaches a basic Energy from the top four cards of your deck. Its attack does 50 damage for each Fire and Lightning Energy attached to all of your Pokémon.
• Mega Golurk ex 047/103: Its attack hits for 300. Its Ability only allows attacks while you have ten or more cards in hand.
• Mega Malamar ex 069/103: Its attack does 70 damage for each of your opponent's Benched Pokémon.
• Mega Golisopod ex 011/103: Its attack does 60 damage and 160 more if your opponent already has a damage counter on them.

Confirmed secret rares so far include Masquerain 104/103, Sprigatito 105/103, Growlithe 106/103, Togedemaru 109/103, Eevee 114/103 and Azurill 115/103. The top card is the Special Illustration Rare Raikou ex 136/103.

What are split Stadium cards?

Delta Reign introduces a card type that has never existed in this form. A split Stadium card consists of two halves that may only be played together. The idea is reminiscent of the LEGEND cards from the HeartGold and SoulSilver era. Because both halves share the same name, only two sets of a Stadium fit into a deck. A booster pack with a split Stadium always contains both halves. (English card names are not yet confirmed, the names below are the German ones.)

• Legendärer Gipfel 096/103 + 097/103: If a Colorless Pokémon is Knocked Out, the opponent takes one fewer Prize card.
• Legendärer Graben 098/103 + 099/103: doubles all healing in play, for both players.
• Legendäre Lavaröhre 094/103 + 095/103: Evolution Pokémon in play have no Abilities, both yours and your opponent's.

Delta Reign or Storm Emeralda?

Both sets have almost the same cards. Delta Reign comes in German and additionally includes most of the new cards from the Mega Starter Set ex decks. One Pokémon ex is expected to be dropped: Storm Emeralda and the starter decks have seven Pokémon ex between them, Delta Reign only six.

Storm Emeralda, on the other hand, is available right now, with Japanese card quality and Japanese layout. If you do not want to wait until November or you collect Japanese cards, you can find the Storm Emerald Display with 30 boosters in our shop.

What is worth it for whom?

• Collectors chasing Raikou ex or Mega Rayquaza ex: a display, because only with many packs do your chances at Special Illustration Rares go up noticeably.
• Beginners and players: the Elite Trainer Box with Kyogre promo, sleeves and accessories, or the Build & Battle Box with a ready-made deck.
• To try it out: the Booster Bundle or the 3-pack blister with the Seel promo.
