Pokémon TCG: Chaos Rising — What to Expect from the Next Mega Evolution Set
Mega Greninja ex takes center stage in the fourth Mega Evolution expansion. Here's what collectors and players need to know ahead of the May 22nd release.

Chaos Is Coming to Lumiose City#
The fourth English set in the Mega Evolution series has a name, a release date, and a headliner that the community has been talking about for months. Pokémon TCG: Mega Evolution — Chaos Rising arrives on May 22, 2026, and if you've been following along with the Japanese sister set Ninja Spinner (which hits shelves in Japan on March 13), you already have a pretty good idea of what's coming.
For everyone else — here's what you need to know.
The Set at a Glance#
Chaos Rising carries the set code ME04 and contains 122 cards, making it another smaller English set in line with recent releases like Perfect Order and Phantasmal Flames. This is a near 1:1 adaptation of Japan's Ninja Spinner, which means the full card list is essentially already known for anyone who's been watching Japanese previews.
The official breakdown:
- 5 Mega Evolution Pokémon ex (Mega Greninja ex, Mega Floette ex, Mega Pyroar ex, Mega Dragalge ex, and likely Mega Gallade ex)
- 5 regular Pokémon ex
- 11 Illustration Rare cards
- 18 Ultra Rare cards (full-arts and Trainer cards)
- 6 Special Illustration Rare cards
- 1 Mega Hyper Rare — the ultra-premium gold-textured tier introduced with this block
The narrative framing is set in Lumiose City, where Mega Floette ex is described as causing chaos in the streets, with Mega Greninja ex rallying other Mega Evolution Pokémon to push back. It's a good hook, and the nighttime city setting comes through clearly in the artwork previews.
The Chase Cards#
There's really one card at the top of the pile, and the community has been aware of it for weeks: the Mega Greninja ex Special Illustration Rare.
Greninja has become one of the most consistently popular Pokémon in the TCG — sitting alongside Charizard and Gengar in terms of collector demand. The SIR treatment shows Mega Greninja moving through a rain-soaked, neon-lit Lumiose, with a full-bleed panoramic illustration that reportedly already looks exceptional in the leaked Japanese version. Pre-release secondary market pricing from Ninja Spinner has placed the Mega Hyper Rare equivalent at high values, with the SIR following closely behind.
Beyond Greninja, the other confirmed SIRs worth tracking:
- Mega Floette ex SIR — the set's antagonist gets a striking full-art treatment
- Mega Pyroar ex SIR — Fire-type, popular in illustration form, and with decent competitive relevance
- Mega Dragalge ex SIR — a more niche pull, but the Dragon typing and artwork have fans interested
- AZ's Tranquility — a Supporter SIR based on the Pokémon Legends: Z-A character, described as emotionally resonant and visually striking by those who've seen the Japanese version
One detail worth highlighting for set collectors: Froakie and Frogadier both have Illustration Rares in this set with connecting artwork leading into Mega Greninja ex. Completing the evolutionary line visually is a strong incentive for binder collectors, even if the IRs themselves won't reach SIR-level prices.
The Xerneas Illustration Rare is also worth noting — a gorgeous card, though it's an IR rather than an SIR. The Kalos legendary gets some overdue attention here, even if the rarity tier might limit its ceiling.
Pull Rates: What a Box Actually Gets You#
Based on Mega Evolution era patterns and early Ninja Spinner opening data, a standard booster display (36 packs) is expected to yield roughly:
- 7–9 Pokémon ex
- 2 full art ex
- 1–2 Illustration Rares
- ~50–65% chance of a Special Illustration Rare
- Mega Hyper Rares appear approximately once every two boxes
SIRs sit at roughly one per 40–50 packs. If chasing the Mega Greninja SIR specifically, the math is the math — single purchases from the secondary market are almost certainly more efficient than buying sealed and hoping.
Products Available at Launch#
The standard product lineup at release on May 22:
- Booster packs (individual)
- Elite Trainer Box — 9 booster packs, Illustration Rare promo card (Fennekin), sleeves, dice, and storage box (MSRP ~$49.99)

Worth Collecting?#
Chaos Rising has a few things working in its favour as a collector set. The smaller card count (122 cards) means the pull rate math is a bit friendlier compared to massive 200+ card sets — the chase slots aren't spread as thin. Greninja's popularity isn't going anywhere, which gives the SIR genuine long-term collector demand rather than just launch hype.
The set also continues the Mega Evolution block's track record of strong illustration quality, which has been one of the genuine highlights of this era for binder collectors who care about the art as much as the rarity.
That said: this is a smaller set, and if you're not chasing Greninja specifically, the overall hit density per box is what it is. Know what you're looking for before you open.
Chaos Rising releases May 22, 2026. Prerelease events run May 9–17 at participating stores.
