Storm Emeralda's main set runs from 001/076 to 076/076, seventy-six cards in total. Add the secret and secret-rare tier printed above that number, twelve Art Rares, eighteen Super Rares, six Special Art Rares and one Mega Ultra Rare, thirty-seven cards altogether, and the full set reaches 113. Pokémon released it in Japan on July 31, 2026, as the sixth main expansion of the Mega Evolution era, and the official Japanese site now lists every card in that checklist.

That 76-card base is smaller than what came before it. Mega Brave and Mega Symphonia, the two versions that opened the era back in January, each carried 92 cards in their main set. Ninja Spinner, released in March, trimmed that to 83. Storm Emeralda continues the same slide, and the difference isn't just trivia: a smaller base checklist means a larger share of what you actually pull points toward the secret-rare tier instead of toward filling out numbered commons.

Four Mega Evolution ex cards carry the set

Mega Rayquaza ex leads at 058/076. It's a 280 HP Colorless Basic with an Ability that searches the top four cards of the deck for a Basic Energy and attaches it the moment the card is played from hand onto the Bench. Its attack costs one Fire, one Lightning and one Colorless Energy, and deals 50 damage for every Fire and Lightning Energy attached across your whole side of the field. The attack's Japanese name is literally Storm Emeralda, the same three words as the set itself.

Mega Golisopod ex sits at 009/076, a 340 HP Grass-type Stage 1 with the more brutal math of the four. Its first attack starts at 60 damage and adds 160 more if the opponent's Active already has damage counters on it, a real number against any deck that's already traded hits. Its second attack locks the target in place for a turn, which matters more in a format built around retreating out of bad attacks than raw damage usually does.

Mega Golurk ex completes the group of four, though it didn't make it into the copies we photographed for this piece. The full gallery with every printed number lives on Pokémon's own checklist and on the usual Japanese TCG trackers, Bill's Archive and Samurai Sword Tokyo among them, if you want to see it directly.

Wishiwashi ex breaks the Mega pattern

Not every strong card in Storm Emeralda evolved from a Mega line. Wishiwashi ex, 021/076, is a plain Basic Water-type with 260 HP and an Ability that heals 50 HP off itself once per turn while it's your Active Pokémon. Its attack costs four Energy and hits for 220, a heavy price for a heavy number, but the healing Ability is what actually makes it annoying to race down in a real game.

Malamar ex, twice over

Mega Malamar ex shows up in two very different looks: 048/076 as the regular RR, and 094/076 as a Super Rare full-art repaint of the same card. Both share the same 320 HP, the same Darkness typing and the same two attacks, one that scales with how many Pokémon sit on the opponent's Bench and one that confuses the opponent's Active outright. The SR isn't a different card in play. It's the same stat line wearing the set's higher rarity tier, which is exactly what a Super Rare is supposed to be in the Japanese system: presentation, not power.

Three Stadium pairs, not the one we already knew about

Our Delta Reign coverage described one two-card Stadium, Legendary Summit, split across cards 96 and 97 of the English set. Storm Emeralda's full checklist shows Japan actually got three of these split Stadiums, and together they take up the entire back end of the main set. Cards 071 and 072 form Legendary Marine Trench. Cards 073 and 074 form Legendary Summit, the same card our Storm Emeralda chase coverage already pictured. Cards 075 and 076 form Legendary Lava Lake, closing out the checklist.

Legendary Marine Trench is the clearest example of what the mechanic actually does. Play both halves together and every Pokémon in play heals double the HP whenever it recovers HP by any means, yours and your opponent's alike. A single half is still a legal Stadium on its own, but the artwork and the intended effect only make real sense once both pieces are on the table, the same collecting problem Legendary Summit already created for anyone chasing a matched pair.

Most of the set still isn't a chase card

It's easy to read a set through its five most expensive cards and forget the other seventy-one. Sableye, 046/076, is a plain Common: an 80 HP Darkness Basic with an attack that forces a Basic Pokémon out of the opponent's deck and onto their own Bench, useful in the right deck, worth close to nothing on its own. That's most of Storm Emeralda. The chase math we covered separately, roughly one SAR per two to three boxes and the MUR closer to one in fifty to one hundred, only applies to a handful of the set's 113 total cards. The other side of it is exactly this: playable Commons and Uncommons that never show up in a price alert.

What this means if you're buying

If you're chasing Storm Emeralda cards as singles rather than opening packs, the smaller main set actually works in your favor. Fewer numbered cards means fewer near-misses between the card you want and one that looks almost identical at a glance, which is less true up in the secret-rare tier, where a regular RR, an SR and an SAR of the same Pokémon can sit two rarity steps and a large price gap apart. Buyers should also expect the counterfeit pressure we've written about separately to follow the money here first, since the SAR and MUR chases sit in exactly the price range that attracts fakes.
