Mega Evolution — Chaos Rising: The Most Important Pokémon TCG Set of Spring 2026

On May 22, 2026, the fourth set of the Mega Evolution era launches worldwide: Pokémon TCG: Mega Evolution — Chaos Rising. For collectors and players in Switzerland, this is one of the most exciting releases of the year — featuring five new Mega Evolution Pokémon ex, over 120 cards, and a storyline set in Lumiose City at night.

At Celestrion, the set is available for pre-order at MSRP, and shipping is directly from Switzerland. This guide gives you the essential information about the set, the chase cards, and all the products available at launch.

What is Mega Evolution — Chaos Rising?

Chaos Rising is the fourth main expansion of the ongoing Mega Evolution era, which started in early 2026 with Ascended Heroes. The storyline: as night falls over Lumiose City, chaos breaks out — Mega Floette ex causes turmoil, and the other Mega Pokémon must rise to meet the threat.

The set contains:

• 5 Mega Evolution Pokémon ex

• 5 regular Pokémon ex

• 11 Illustration Rares (IR)

• 18 Ultra Rares (UR)

• 6 Special Illustration Rares (SIR)

• Over 120 cards total, with more than 35 cards featuring special illustrations

Pre-release tournaments took place from May 9 to 17, 2026 — players who attended already got hands-on with the first Build & Battle Boxes featuring the promo cards Delphox, Ampharos, Crobat, and Goodra.

The 5 Mega Evolution Pokémon ex in Detail

Mega Greninja ex

The flagship card of the set. Greninja has always been a fan favorite, and the Mega Evolution returns him as the protagonist defending the city against Mega Floette. For competitive players, Greninja is one of the most interesting new deck options of the season.

Mega Floette ex

The antagonist of the set's storyline. Mega Floette ex brings chaos to the city and is visually one of the most unusual Mega Evolutions — a seemingly harmless Pokémon turned threat. Collectors will be watching the Illustration Rare and SIR versions in particular.

Mega Pyroar ex

A Fire-type Mega Evolution with an aggressive playstyle. Pyroar rounds out the trio with Greninja and Dragalge as they stand against the threat.

Mega Dragalge ex

An unusual choice for a Mega Evolution — Dragalge is a niche card in competitive play, but as a Mega version with high-quality artwork it's likely to be an attractive collector piece.

Fifth Mega Pokémon ex

The set's final Mega Pokémon completes the lineup. Details will be confirmed at launch — the Special Illustration Rare is likely to be one of the most sought-after cards in the set.

Chase Cards: What Collectors Should Watch

For Chaos Rising, the 6 Special Illustration Rares (SIR) are the cards with the highest collector value. SIRs are full-art illustrations with alternative artwork — they're the most valuable pulls from Booster Boxes and the cards traded most actively on the secondary market.

Beyond the SIRs, also keep an eye on:

• The 11 Illustration Rares (IR) — cheaper than SIRs, but often with artwork that appreciates long-term

• The Mega Pokémon ex in Ultra Rare format — playable cards in high demand from competitive players

• Trainer cards with special illustrations — particularly Supporter cards see heavy competitive play and are sought-after as SIR versions

Which Chaos Rising Products Are Available at Celestrion?

Booster Box (Booster Display)

The Booster Box contains 36 Booster Packs with 10 cards each plus one Basic Energy. This is the best product for collectors who want to chase the full set and the most reliable way to pull multiple SIRs. Available at MSRP.

Elite Trainer Box (ETB)

The standard choice for players and collectors. Each Chaos Rising ETB contains 9 Booster Packs, a full-art promo card featuring Fennekin, 65 card sleeves, 40 Energy cards, damage counter dice, a coin-flip die, a plastic coin, and a player's guide. Bonus: everything comes in a high-quality storage box that doubles as a long-term organizer.

3-Pack Blister & Booster Bundle

For collectors who don't want to commit to a full box. The Booster Bundle contains 6 packs, the 3-Pack Blister even smaller quantities — solid entry products or supplements for targeted pulls.

Additional Releases on May 22, 2026

Two more important products launch alongside Chaos Rising:

Mega Zygarde ex Premium Collection

A premium box containing a foil promo card featuring Mega Zygarde ex, an oversize lenticular card, a tech sticker, and 8 booster packs from various expansions. Premium Collections are popular with collectors targeting exclusive promo cards.

Mega Lucario ex League Battle Deck

A ready-to-play 60-card deck featuring Mega Lucario ex as the centerpiece. Includes reprints of Secret Box and Fezandipiti ex — both cards seeing significant play in current decks. For competitive players, the League Battle Deck is an affordable way to get multiple meta-relevant cards at once.

Bottom Line

Chaos Rising is one of the visually strongest sets of the Mega Evolution era. For collectors, the SIRs are the main draw; for players, the new Mega Pokémon ex and the meta cards in the League Battle Deck. Anyone who wants the set at launch should pre-order now — the Premium Collection and ETBs tend to sell out fast.
