Storm Emeralda (set code M6) launches in Japan on Friday 31 July 2026, and the main set is already fully revealed: 76 cards, with Mega Rayquaza ex on the cover and an idea the game has not used since the LEGEND era, Stadiums printed across two separate cards that you have to play together.
This article is the complete list of the main set alone, card by card, with large images: tap any card to start tracking its value on DarkDex. No rankings and no prices, because the set is not out yet and the DarkDex price engine does not have a single listing to show on these cards.
In short. Storm Emeralda (M6) is out on 31 July 2026 in Japan, 7 August in Taiwan and Hong Kong. The main set is 76 cards: 8 ex (four of them Mega ex), 7 Holo Rares, 21 uncommons and 40 commons. The special rarities from number 077 up have not been fully revealed, and no card has a price yet. Data as of 28 July 2026.
When does Storm Emeralda come out
In Japan on Friday 31 July 2026, one week to the day from this article. Taiwan and Hong Kong follow on 7 August. It is the sixth set of the Mega Evolution era, and its official code is M6.
These cards do not reach Europe on 31 July. Japanese sets come first and are then reshuffled into Western releases a few months later, often under a different name: it happened days ago with Abyss Eye, which arrived in the West as Pitch Black. So if you are looking for Storm Emeralda in English, for now only the Japanese edition exists.
The four Storm Emeralda Mega ex
Mega Rayquaza ex (#058) is the mascot and it gives the set its name: "Storm Emeralda" is the name of its attack, which does 50 damage for each Fire and Lightning Energy attached to all of your Pokémon. It is Colorless, it has 280 HP, and its Ruler's Roar Ability lets you look at the top four cards of your deck and attach a Basic Energy to it when you put it on your bench from hand.
Mega Golurk ex (#033) is the wall: 350 HP, the highest in the set, and Goliath Punch for 300 damage on just two Psychic Energy. The bill comes with its Power Limiter Ability, which stops it from attacking unless you have ten or more cards in hand, and with the 30 damage it puts on itself every swing.
Mega Golisopod ex (#009) is Grass, 340 HP: Finishing Blow starts at 60 damage but hits for 220 if the opponent's Active Pokémon already has damage counters on it. Mega Malamar ex (#048) is Darkness, 320 HP, and Psychic Marionettes does 70 damage for each of your opponent's Benched Pokémon: the wider they go, the more it hurts.
One rule covers all four: when a Mega Evolution Pokémon ex is Knocked Out, your opponent takes three Prize cards instead of two. That HP and that damage are not free.
Sign up free on DarkDex and add the cards to your collection now: the value switches on by itself as soon as the market posts its first listings, without you chasing them one by one.
The other four ex
- Talonflame ex (#062), Colorless, 280 HP: its Elated Dive Ability puts it straight onto your bench from hand if you have a Colorless Mega Pokémon ex in play. That means Mega Rayquaza ex: this card is written to travel with it.
- Raikou ex (#024), Lightning, 200 HP: Gather Lightning can be used on your first turn if you go first, and pulls a Lightning Energy out of the deck onto it.
- Wishiwashi ex (#021), Water, 260 HP: Oceanic Gain heals 50 damage per turn while it is Active, and Hydro Gain does 220.
- Heat Rotom ex (#015), Fire, 190 HP: Reheat does 30 damage for each Basic Fire Energy in your discard pile, then shuffles them back into the deck.
The Stadiums you play in halves
This is the real structural novelty of the set. Each of the three "Legendary" Stadium cards is printed across two different card numbers: the artwork continues from one half into the other, and the text says you must play both halves at the same time from your hand for them to count as a single Stadium. Anyone with a few years of play behind them will recognise the LEGEND cards from HeartGold & SoulSilver.
What they do:
- Legendary Ocean Trench (#071 + #072): whenever any Pokémon is healed, the healing is doubled. On top of Wishiwashi ex that turns into 100 HP a turn.
- Legendary Summit (#073 + #074): whenever a Colorless Pokémon is Knocked Out by an opponent's attack, the opponent takes one fewer Prize card. On Mega Rayquaza ex, which is Colorless, that means three Prizes become two.
- Legendary Lava Lake (#075 + #076): Evolution Pokémon in play, yours and your opponent's, have no Abilities.
For collectors there is a practical consequence: the main set does not close on 76 different cards, it closes on 76 numbers, and three of those entries are pairs worth keeping together.
The seven Holo Rares
Seven cards, and the Hoenn theme is easy to spot: Groudon (#039) and Giratina (#031) are the headline names, but Altaria, Kommo-o, Nidoqueen, Arcanine and Cacturne all get a slot. Kyogre is in the set too (#018), but as a common, not a Holo Rare.
The Forces of Nature quartet
Tornadus (#059), Thundurus (#025), Landorus (#040) and Enamorus (#034) share the same Ability, Incarnate Union: with all four in play, the Colorless Energy in their attack costs is ignored. Four uncommons, so pocket change on the shelf, but a clear job to do in a deck.
The rest of the Trainers digs deep into Hoenn: Zinnia's Trust (#069), Tate & Liza's Training (#070), Aarune (#068) and the Mega Rayquaza cap (#066), already the most charming card in the set.
The Storm Emeralda chase cards: SR, AR and SAR
Everything above number 076: the SR, AR, SAR and the other special rarities, which in recent Japanese sets soak up most of the money in a box. Around forty of them are expected, and none is in the catalogue yet. As soon as they land we will publish the chase card article, with the images and the real prices.
There is a useful precedent right here: on Pitch Black, one week after release, the top three cards in the ranking were all full art and were worth more on their own than the rest of the set put together. We expect Storm Emeralda to follow the same shape, with Mega Rayquaza ex in the Mega Darkrai ex role.
How much are Storm Emeralda cards worth
Today, nothing: none of the 76 cards has a price, because the set is not out and no listings exist. Be wary of anyone quoting precise values before 31 July: those are estimates, not prices.
Real values appear with the first sales, in the days right after the Japanese release, and at first they swing hard: in week one, stock, hype and day-one demand weigh more than the set will six months from now. The numbers become trustworthy later, once the mass box opening dries up.
When that happens, the cards are already in the DarkDex catalogue, in any language and condition, with price history card by card. And we will publish the ranking of the most expensive ones here, exactly as we did for the most expensive Pitch Black cards and for the prices one week after launch.
Careful. As of 28 July 2026 Storm Emeralda is not out yet and none of the 76 cards has a price, simply because there are no listings. Prices arrive after release, and they move a lot in the first few weeks.
Storm Emeralda FAQ
How many cards are in Storm Emeralda?
The main set is 76 cards (001 to 076). On top of those come the special rarities above 076, not fully revealed yet, which will push the total well past a hundred.
What is the best card in the set?
For play it depends on the deck, but the flagship is Mega Rayquaza ex (#058): it gives the set its name through its attack, and the rest is built around it, Talonflame ex and Legendary Summit included. For value, the full art versions will have the last word, and they have not been shown yet.
Is Storm Emeralda coming out in English?
Not under this name and not now. It is a Japanese set: its cards will come back later inside a Western release, the way Abyss Eye came back as Pitch Black.
What are the Stadiums printed across two cards?
Three Stadiums (#071 + #072, #073 + #074, #075 + #076) split into two halves: you play them together from your hand and they count as a single Stadium, with the two illustrations joining into one. It is the same idea as the LEGEND cards from HeartGold & SoulSilver.
Is a Storm Emeralda booster box worth buying?
Right now that cannot be answered with numbers, because neither pack prices nor card prices exist. The rule that always holds: the value of a box sits in a handful of cards at the top, so compare the box price against those, not against the set as a whole.
How to keep an eye on them from day one
On DarkDex you can add your Storm Emeralda cards to your collection right now, before release: the value switches on by itself as soon as listings appear, with price history and your portfolio total always in view. It is how you watch a set move from day one instead of reconstructing it afterwards.
Come back after 31 July: we will update this page with prices and publish the chase card article as soon as they are revealed.
