Chaos Rising: The Mega Greninja Set Everyone Saw Coming
Set code: ME04 · Released May 22, 2026 · 122 cards · Fourth Mega Evolution expansion
The newest English Pokémon set dropped three days ago. You already know the story if you've walked into a shop this week. This is a Mega Greninja set. Everything else in the box is the supporting cast.
That's not a knock. It's just where the value and the attention sit. Here's the full breakdown — what the set is, what to chase, what it costs right now, and the one rule change that actually matters at the table.
What Chaos Rising Actually Is
Chaos Rising is the English version of Japan's Ninja Spinner. It's a small, focused set — 122 cards. The English print added three numbered cards Japan didn't get: Mega Gallade ex, Krookodile ex, and the Adversity Policy trainer. That's worth noting, because English sets usually ship with fewer cards than the Japanese version, not more. This time EN collectors came out ahead.
Small set size works in your favor if you're opening product. Fewer cards in the pool means better odds at any specific chase card. There's less filler to pull through. January's Ascended Heroes was a 290-card monster — Chaos Rising is the opposite. Lean and direct. The tradeoff is that a small set tends to live or die on its top card, and this one definitely does.
The Cards Worth Chasing
The value here is stacked at the very top. One card runs the whole set, and there's a hard drop right behind it. Know that going in.
Mega Greninja ex
Greninja sits in the top three most popular Pokémon worldwide and has for years — the Smash Bros. crowd locked that in. His Mega design has been one of the most-requested cards in the game's history. So the demand isn't a surprise. What matters is how the printings break down:
- Mega Hyper Rare (gold) — the top card of the set. The Japanese version was already trading near $500 before English packs shipped. Same ceiling here.
- Special Illustration Rare (#116) — the full-art version, and the one most collectors actually want to own. Running $470–600 depending on the day. This is the artistic centerpiece of the set.
- Full Art Ultra Rare — stronger than a Full Art usually sells for, riding the same wave.
- Double Rare — the version you actually play, around $4.
Hold on that last number. Nearly every other Double Rare in the set sells for 75 cents or less. The playable Greninja is worth several times any other card at its rarity. If you want a single number that tells you where this set's demand is pointed, that's it.
Mega Gallade ex — the English exclusive
This is the one to watch if you can pull your eyes off the frog. Mega Gallade ex is a Fighting-type, 350 HP, and it's English-only — it came from a January 2026 Japanese special set and was never in Ninja Spinner. English exclusives tend to age well for a simple reason: there's no Japanese print run flooding the supply, so demand has nowhere else to go. Easy to overlook right now. Worth keeping on the list.
Everything else in the chase tier
The other Special Illustration Rares — Mega Floette ex, Mega Pyroar ex, Mega Dragalge ex — are landing around $55–$109 each. There's also a Froakie / Frogadier / Greninja connected-art triptych at the Illustration Rare tier that collectors are displaying as a single three-card piece. Froakie peaked near $54 in pre-release and has settled around $26, but the three together have held interest better than any single mid-tier SIR.
The Rule Change Nobody's Talking About: Unstable Evolution
This is the part getting buried under price talk, and it's the thing that actually changes how the game plays.
Since the Mega Evolution era started, evolving into a Mega ex ended your turn. No attack that turn, every time. Pure downside. Chaos Rising changes that into a coin flip — Unstable Evolution:
- Heads: the evolution works, your turn continues, and you can attack with the Mega you just evolved.
- Tails: the Mega takes 50 damage and your turn ends. No attack.
It turns a guaranteed loss of tempo into a 50/50 shot at a huge swing. That's a real shift, and it'll decide whether the Mega decks in this set are competitive or just good-looking. For Standard, Mega Greninja ex has a real case on its own — Water already has strong energy acceleration, and its spread damage punishes bench-heavy boards.
Should You Buy In?
Your call, not mine. But here's the straight version for each kind of buyer.
Building the master set: your whole budget comes down to one decision — your Greninja position. SIR only (~$470–505), Mega Hyper Rare only (~$400–485), both (~$900), or neither. That single call, plus the cluster of non-Greninja SIRs, is the difference between a $300 set and a $1,500 one. The rest is cheap.
Opening product for fun: the small set size is on your side. Better hits per box than the bloated sets, and the triptych is a satisfying display goal you can actually reach without the $500 gold.
Holding for later: Greninja's reach rivals Charizard with younger fans, and sealed product tends to hold a premium on hype like this. But the set leaked almost entirely before launch, prices are still bouncing while packs flood in, and a one-chase-card set is a one-card bet. Buy it knowing that's what it is.
One more thing on the clock: Pitch Black drops July 17 with Mega Darkrai ex. Attention moves to the next set fast. If you're completing Chaos Rising, you've got a short window before the spotlight shifts.
Bottom Line
Small set, one massive card. Unstable Evolution is the sleeper, Mega Gallade ex is the quiet pick, and Mega Greninja ex is the whole show. It was always going to be a Greninja set. Go get your frog.
