Storm Emeralda

Set Overview

Storm Emeralda is the sixth Japanese expansion of the Mega Evolution era. It released in Japan on 31 July 2026.

The set is based on Rayquaza ex, a card first printed in 2003 in EX Dragon. Rayquaza was also the mascot of Pokémon Emerald, released in Japan in 2004.

The Japanese set has 76 cards in the main set. The Art Rares, Special Art Rares and the Mega Ultra Rare take the total to 113. A master set is all 113 cards.

The set was first revealed in June 2026, alongside the English Delta Reign and the Pokémon TCG Pocket set Ruler of the Skies. The main set list was revealed on 23 July 2026.

See below for the 76 main set cards and the 37 AR, SAR and MUR cards.

Storm Emeralda saw the return of connected cards. Three Legendary Stadium cards were released: Legendary Ocean Trench, Legendary Summit and Legendary Lava Lake. Each one is split across two numbered halves that join to form a single artwork, and both halves must be played together. See Connected Cards for how the mechanic works.

Main Set Cards

All 76 main set cards were revealed on 23 July 2026. The set is led by its mascot Mega Rayquaza ex and contains four Mega Evolution ex cards in total: Mega Rayquaza ex, Mega Golisopod ex, Mega Malamar ex, and Mega Golurk ex. It also introduces three split “Legendary” Stadium cards: Legendary Ocean Trench, Legendary Summit, and Legendary Lava Lake. Each is printed across two numbered halves that must be played together as a single Stadium, echoing the LEGEND cards of the HeartGold & SoulSilver era. The four Forces of Nature (Tornadus, Thundurus, Landorus, and Enamorus) share the same Incarnate Union Ability. Mega Gallade ex, a connected tournament promo, is shown at the end of the gallery.

Storm Emeralda Chase Cards

Eight cards carry almost all of the set’s value. Mega Rayquaza ex takes three of the top four places, and its Mega Ultra Rare at 113/076 is the only MUR in the set. Both leaders have fallen since the start of the month: the MUR is down from ¥248,000 to ¥178,000 and the 110/076 Special Art Rare from ¥99,800 to ¥69,800 between 6 and 23 August 2026. Below the top five the set flattens out. The three Art Rares in sixth to eighth are all listed at ¥1,980, and the next three cards sit just ¥200 below, so the gap between a good pull and an ordinary one is narrow.

Prices are Yuyu-tei’s listed sell price on 23 August 2026, converted at ¥158.9 to the US dollar, and move with the market. For the full ranking and the cards that just missed, see the 10 most valuable cards in Storm Emeralda.

Master Set: The 37 Secret Rares

Storm Emeralda’s secret rare section runs from 077 to 113 and sits beyond the numbered 76-card main set. All 37 are shown below. They cover the Art Rares, the full-art ex cards and Trainers, three special Energy, the Special Art Rares, and the single Mega Ultra Rare that closes the set at 113/076. The first two, Growlithe (078/076) and Groudon (084/076), appeared on 26 July 2026 in the pre-release pack opening video on the official Pokémon Card Channel.

Connected Cards

The Pokémon TCG has used a handful of connected card mechanics over the years, where a single card is split across, or built from, more than one physical card. Storm Emeralda brought the idea back with its three Legendary Stadium cards. Here is how each mechanic works.

LEGEND

A Pokémon LEGEND is split across two cards — a top half and a bottom half. You must have both halves in play at the same time to use it. Introduced in the HeartGold & SoulSilver era (2010).

Example: Ho-Oh LEGEND — top & bottom halves (HGSS)

V-UNION

A V-UNION Pokémon is made of four separate cards. You assemble all four from your discard pile onto your Bench to put the complete Pokémon into play. Introduced in the Sword & Shield era.

Example: Greninja V-UNION — four cards (SWSH)

Split Stadium

A split Stadium is spread across two cards that share one artwork. Neither card can be played alone — you combine both from your hand and play them as a single Stadium. Introduced in Storm Emeralda, which has three: Legendary Ocean Trench, Legendary Summit and Legendary Lava Lake.

Example: Legendary Trench — both halves form one Stadium (Storm Emeralda)

Physical Products

Storm Emeralda released in the standard Japanese booster format. Both the booster box and the single pack carry the Mega Rayquaza ex artwork.
