Pokémon Chaos Rising is set to release on May 22, 2026, giving the Mega Evolution era its fourth expansion and one of its most story-driven themes yet. Built around the world of Pokémon Legends: Z-A, the set drops collectors and players into a Kalos-region crisis centered on Lumiose City, where Mega Floette ex and Mega Greninja ex stand at the heart of the conflict.
For collectors, Chaos Rising has multiple hooks. Mega Greninja ex leads the product line and the chase conversation, while AZ’s Tranquility adds one of the most emotional character cards in the release. For players, the headline is the return of Mega Evolution with a new gameplay twist called Unstable Evolution, a mechanic that adds risk to the reward of powering into bigger attackers.
The set includes 122 total cards, made up of 86 base cards and 36 secret rares. It features Double Rares, Illustration Rares, Ultra Rares, Special Illustration Rares, and one Mega Hyper Rare, giving the release plenty of depth across sealed ripping, deckbuilding, and high-end collecting.

Mega Greninja ex is the set centerpiece
Chaos Rising is clearly built around Mega Greninja ex. Greninja has long been one of the franchise’s most popular Pokémon, and its Mega Evolution debut gives the set an immediate identity. From a branding standpoint, it is the face of the expansion. From a market standpoint, it is also the card family many collectors will target first.
The biggest visual draw tied to Mega Greninja ex is a connected three-card artwork spanning Froakie, Frogadier, and Mega Greninja ex. Froakie and Frogadier appear as Illustration Rares, while Mega Greninja ex lands as a Special Illustration Rare. Together, the trio forms a panoramic scene that should make complete sets especially attractive to collectors who value display appeal as much as rarity.
That alone would have been enough to keep attention fixed on the line, but competitive interest adds another layer. Players have already been tracking tournament chatter connected to Japanese play, and Mega Greninja ex entered the English release with more momentum than most set mascots receive. That mix of playable buzz and collector appeal usually creates strong early demand.
How Unstable Evolution changes Mega Evolution decks
The biggest gameplay addition in Chaos Rising is Unstable Evolution. Under this mechanic, evolving into a Mega Pokémon ex does not automatically end your turn. Instead, you flip a coin. On heads, the evolution succeeds and your turn continues normally.
That creates a very different kind of Mega Evolution deckbuilding puzzle. The upside is obvious. If the coin lands in your favor, a player can reach a stronger board state without surrendering tempo. The risk is just as important, though, because the mechanic introduces variance into turns that would usually be carefully scripted.
For competitive players, that means Chaos Rising is not just another release with stronger attackers. It is a set that asks players to decide how much uncertainty they are willing to accept in exchange for explosive turns. Cards that improve setup consistency, mitigate bad flips, or take maximum advantage of a successful Mega evolution will be watched closely as decklists develop.
Xerneas, Special Red Card, and some of the utility Trainers in the set may also draw attention because they fit the type of tempo-sensitive environment that Unstable Evolution can create. Even before the full English metagame settles, Chaos Rising looks positioned to matter in both local play and broader tournament conversation.
Top chase cards in Pokémon Chaos Rising
The top card on many collector want lists is card 122, Mega Greninja ex Mega Hyper Rare. It sits alone at the top of the rarity ladder and enters release week as the set’s primary prestige pull. Whenever a popular Pokémon gets the only card in a highest-tier rarity, demand tends to form quickly, and Chaos Rising fits that pattern.
The six Special Illustration Rares are the next major targets. Mega Greninja ex SIR should remain a headline card because of its connection to the Froakie and Frogadier Illustration Rares. Mega Floette ex SIR and Mega Dragalge ex SIR also strengthen the premium side of the set, while Cinccino ex SIR gives the lineup a slightly different flavor from the usual Mega-heavy upper tier.
AZ’s Tranquility SIR may wind up being the card with the broadest emotional appeal. The artwork centers on AZ and Floette, tapping directly into one of the more memorable story threads from the Kalos era. Story-based Trainer cards often perform well when they land with fans, and this one looks positioned to become a standout even beyond pure scarcity.
Roxie’s Performance SIR rounds out the SIR lineup, and Special Red Card appears as an Ultra Rare with meaningful competitive relevance. That matters because playable full-art Trainers often age well if they remain useful in decks.

Set size, rarity breakdown and collector snapshot
Chaos Rising has 86 main-set cards and 36 secret rares for a total of 122 cards. That gives it a manageable core checklist with a substantial premium layer above it. The rarity mix is broad enough to support both affordable collecting and more ambitious rainbow-topper style chasing.
- Common: 38
- Uncommon: 26
- Rare: 12
- Double Rare: 10
- Illustration Rare: 11
- Ultra Rare: 18
- Special Illustration Rare: 6
- Mega Hyper Rare: 1
The 11 Illustration Rares offer a particularly balanced middle ground for collectors. Chespin, Froakie, Frogadier, Ampharos, Xerneas, Claydol, Crobat, Metang, Sliggoo, Tauros, and Watchog all receive IR treatment. That variety helps broaden the appeal of the set beyond just the marquee Mega cards.
Collectors chasing themed pages will also notice several evolutionary lines that work well in binders, especially the Froakie to Frogadier to Mega Greninja ex progression and the Beldum to Metang line paired with Metang’s Illustration Rare appearance.

What collectors should watch at launch
Early attention is likely to center on three parts of the checklist. The first is the premium Mega Greninja ex ladder, especially the SIR and MHR versions. The second is the connected Froakie and Frogadier Illustration Rares, which could see strong demand from collectors who want the full visual sequence. The third is AZ’s Tranquility SIR, a card with the kind of story resonance that can keep collector demand healthy even after release-week hype fades.
On the playable side, Special Red Card is one of the trainer names worth monitoring, while Mega Evolution decks as a whole will shape how much sealed demand stays elevated after launch. If Unstable Evolution strategies prove strong enough to matter consistently, Chaos Rising could remain relevant well beyond the initial opening weekend, with Mega Greninja ex and the set’s premium Trainers sitting at the center of that interest.
