Size and origin of the set

Delta Reign holds more than 135 cards, 103 of them regular and the rest secret rares. That makes it the largest main set since Mega Evolution from September 2025.

The contents come from two Japanese sources. It takes over almost all 113 cards of the Japanese expansion Storm Emeralda plus most of the new cards from the Japanese Mega Starter Set ex Decks. One Pokémon ex is expected to be left out: Storm Emeralda and the starter decks together hold seven Pokémon ex, Delta Reign only six.

The official description reads: “A thundering rumble announces the arrival of a glorious ruler of the skies! Mega Rayquaza ex's unmatched strength in battle inspires Mega Golurk ex, Mega Malamar ex and Mega Aggron ex to step forward and put their own abilities to the test.”

The four Mega Pokémon ex

Rayquaza returns in its Mega form for the first time since the XY series. Three further Mega Pokémon ex join it:

  • Mega Rayquaza ex 084/103 – the Ruler's Roar Ability attaches a Basic Energy from the top four cards when played. Emerald Storm does 50 damage for every Fire and Lightning Energy attached to all of your Pokémon.
  • Mega Golurk ex 047/103 – Goliath Strike hits for 300 damage with 30 recoil. The Limited Activation Ability only allows attacks with ten or more cards in hand.
  • Mega Malamar ex 069/103 – Psychic Puppetry does 70 damage per Benched Pokémon your opponent has. Spectral Surge hits for 200 and confuses.
  • Mega Aggron ex 011/103 – Final Strike does 60 damage and 160 more if a damage counter is already on your opponent. Fourfold Grip hits for 160 and prevents retreat.

Legendary Stadium cards: the new mechanic

The set introduces a card type that has not existed in this form before. Legendary Stadium cards consist of two halves and may only be played together. The principle recalls the LEGEND cards from the HeartGold and SoulSilver series.

Because both halves carry the same name, a deck may only hold two sets of any one Stadium card. Booster packs containing a Legendary Stadium always deliver both halves. Three stadiums are confirmed so far:

  • Legendary Peak 096/103 and 097/103 – when a Colorless Pokémon is knocked out, that player's opponent takes one fewer Prize card.
  • Legendary Trench 098/103 and 099/103 – doubles every heal in play, for both players.
  • Legendary Lava Lake – Evolution Pokémon in play have no Abilities.

Secret rares and promo cards

Above the 103 regular cards sit the secret rares. Confirmed so far are Masquerain 104/103, Sprigatito 105/103, Growlithe 106/103, Pincurchin 109/103, Eevee 114/103, Azurill 115/103 and at the top the Special Illustration Rare Raikou ex 136/103.

Three promo cards follow, each tied to a product:

  • Spritzee MEP 115 – in the checklane blister
  • Seel MEP 116 – in the 3-pack blister
  • Kyogre MEP 117 – in the Elite Trainer Box

What this means for buying

A set this size with a draw like Mega Rayquaza pulls a lot of demand at launch. The card list is known, the date is set, and pre-orders typically open six to eight weeks before release. If you want a display, put 6 November in your calendar.

Because Delta Reign builds almost entirely on Storm Emeralda, the Japanese set is a good guide to which cards will be sought after. The Special Illustration Rares and the three Legendary Stadiums are where the attention will concentrate.
