Chaos Ascendant (ME04) card preview
What is Chaos Ascendant (ME04)?
Pokémon Mega Evolution: Chaos Ascendant is the fourth major expansion in the block that launched in fall 2025, tied directly to Pokémon Legends Z-A. In English the set is Chaos Rising (ME04); in France it hit shelves on Friday, May 22, 2026.
After Mega Evolution, Phantasmal Flames, and the block’s interim releases, ME04 refocuses the series on Kalos and chaos in Lumiose—less a rules revolution than a new visual and narrative chapter. The set is generous for collectors: a little over 120 cards, including dozens of special illustrations starring Pokémon and Trainers. You’ll find five Mega ex, eleven Illustration Rares, eighteen Ultra Rares, and six Special Illustration Rares!—enough to fuel openings and the secondary market for weeks.
Chaos Ascendant story: chaos in Lumiose
On story, The Pokémon Company sets the scene: night falls on Lumiose, the City of Light in Kalos, and Mega Floette ex spreads chaos in the streets. To push back, players can count on Mega Greninja ex as the set’s headline, flanked by Mega Delphox ex and Mega Chesnaught ex—Pokémon straight from Pokémon Legends Z-A. As with every expansion in the block, the latest video game shapes the paper collection.
Why does the Mega Evolution release pace divide fans?
Since October 2025, shelves haven’t caught a break: five Pokémon TCG expansions in barely eight months—a pace even collectors struggle to follow, not to mention TCG Pocket and its own rotations (Paradox Rift). The Pokémon Company was already citing “very high demand” in spring 2025 after Prismatic Evolutions and Destined Rivals shortages; with so many wallets stretched, shortages have become almost structural.
Facing pushback from specialty shops, some distributors cap purchases (often two items per person) or target scalping. On the publisher side, the promise is more printing—but on the ground, the window around May 22 is still when supply is most abundant before chase cards climb.
What are the chase cards in Chaos Ascendant?
Mega Evolutions still dominate the set. Mega Greninja ex (Greninja in English) is the competitive and collector star: its Mega Hyper Rare 122/086 is currently the top chase, with pre-order estimates around €400. Mega Floette ex embodies the narrative chaos; Mega Delphox ex and Mega Chesnaught ex round out the Kalos trio. Other ex in the set—Pachirisu ex, Beedrill ex, Cobalion ex, Gourgeist ex, Krookodile ex—add competitive depth and themed collections.
Illustration Rare and Ultra Rare
- Illustration Rare (11): Froakie, Frogadier, Ampharos, Xerneas, Gardevoir, Golbat, Metagross, Sliggoo, Tauros, Heliolisk, Chespin…
- Ultra Rare / Full Art: Beedrill ex, Mega Delphox ex, Mega Greninja ex, Mega Floette ex, Gourgeist ex, Cobalion ex, Mega Chesnaught ex, Pachirisu ex, Emma, Energy Retrieval, Special Red Card…
Special Illustration Rare (SIR) — the priciest
- Mega Greninja ex (116/086) — chase SIR, ~€400 pre-release
- Mega Floette ex (117/086) — narrative art, high demand
- Mega Chesnaught ex (118/086) — ~€115 estimated
- Pachirisu ex (119/086)
- AZ's Tranquility (120/086) — ~€125 estimated
- Roxie's Performance (121/086)
What are the Chaos Ascendant (ME04) pull rates?
ME04 shares the me_standard pull model of other Mega Evolution (ME01, ME02) sets. Each booster has 10 cards plus a basic Energy and a Pokémon TCG Live code. Exact rates are never published officially; estimates below come from community pre-release openings.
- Double Rare (ex): ~1 in 4 packs
- Illustration Rare: ~1 in 10 packs
- Ultra Rare: ~1 in 13 packs
- Special Illustration Rare (SIR): ~1 in 30–40 packs
- Mega Hyper Rare (gold): ~1 in 80–120 packs
For one specific SIR (e.g. Mega Greninja ex), divide the global SIR rate by the number of SIRs in the set (~6): odds per pack stay low, and buying the single on the secondary market is often more rational than dozens of openings.
Is a 6-pack ME04 bundle worth it?
The 6-pack Mega Evolution: Chaos Ascendant (ME04) bundle is the most accessible entry on Amazon (~€36 at launch, depending on offers). Six boosters × 10 cards = 60 cards total, all random from the set—see the 6-pack listing in the grid above.
- Good odds of 1–2 hits (an ex or Illustration Rare)
- Often: at least one Double Rare Pokémon ex
- A SIR or Mega Hyper Rare is still very unlikely in only 6 packs
- Community reports vary—sometimes 2 IRs in 20 packs, sometimes no SIR in 60+ — variance is real
Which sealed products for Chaos Ascendant ME04?
The ME04 line follows usual Pokémon TCG formats. Indicative MSRPs below are launch benchmarks—compare our price page and Amazon when you buy.
- Single booster — ~€5.99 — occasional try
- 6-pack bundle — ~€36 — best way to sample the set without an ETB
- Elite Trainer Box (ETB) — 9 packs, Fennekin promo, sleeves, dice, guide — ~€55.99 — players and collectors
- 36-pack display — ~€180 — high volume
- Battle Strategies box — 40-card prerelease deck + 4 boosters + holo promo

Each Elite Trainer Box includes 9 ME04 boosters, a full-art Fennekin promo, 65 sleeves, 40 Energy cards, game accessories, and a guide to build a deck from the expansion. The ETB remains the reference format for booster volume plus useful local-league accessories.
Chaos Ascendant competitive impact: meta picks
Mega Greninja ex should weigh heavily on the Standard meta after ME04, with synergies around Mega Evolution decks already tested in Play! Pokémon pre-releases. Support cards like Secret Box and Dudunsparce ex (from other products in the block) stay in demand. Pre-releases let you refine lists before street date—handy for local Pokémon Leagues.
Chaos Ascendant vs ME01, ME02 and the Mega Evolution block
ME01 (Mega Evolution) popularized Mega Charizard and Mega Lucario; ME02 (Phantasmal Flames) focused Fire, Darkness, and Psychic with Mega Charizard X ex; ME03 and ME04 extend the Z-A and Kalos link. If your budget covers one set in the block, ME04 offers the freshest art and the Lumiose narrative—but ME01–ME02 SIRs already have established price history. A balanced play: one ME04 ETB plus a few ME02 boosters.
