Chaos Rising (ME04): Is It Worth Buying?
Chaos Rising landed on May 22, 2026 as the fourth English set of the Mega Evolution era, and it arrived with a very clear identity: fast, sneaky, and built around one of the most popular Pokémon of the past decade. Two months after release, the dust has settled enough to answer the real question — should you buy it?
What Chaos Rising is
The set runs to 122 cards once the secret rares are counted, sitting on a base list of 86. It is a compact set by modern standards, which cuts both ways: fewer filler cards, but also fewer lottery tickets in the rare slots. The headline mechanic is unchanged from the rest of the era — Mega Evolution Pokémon ex that hit extremely hard and give up three prizes when they go down — and Chaos Rising contributes five new Mega ex to that roster, six Special Illustration Rares, and a single gold Mega Hyper Rare at the very top of the rarity ladder.
Coming just two months after March's Perfect Order (ME03), Chaos Rising had every chance to feel like filler. It does not — largely because the theme is coherent. Water, poison and fighting types dominate, the artwork leans into night scenes and motion, and the whole set reads like it was designed around its cover star rather than assembled from leftovers.
Chase cards to know
This is Mega Greninja's set, full stop. The Mega Greninja ex Special Illustration Rare is the card everyone opens for, and interestingly it has led the set's prices since day one — ahead of the gold Mega Hyper Rare version of the same card, which is technically the rarer pull. That inversion says a lot about how much collectors currently favor SIR artwork over gold treatments.
Behind the frog, the supporting cast is stronger than a 122-card set has any right to be: the Mega Dragalge ex Special Illustration Rare is a moody standout, Mega Gallade ex gives fighting decks a genuine reason to open packs, and the Cinccino ex Special Illustration Rare has been the set's lovable surprise — an unassuming Pokémon with artwork good enough to hold a real price. For what each of these goes for right now on Cardmarket and TCGplayer, see the live Chaos Rising top cards page.
One practical note: because the Greninja SIR is the card people grade from this set, condition matters from the second you pull it. Sleeve it immediately, check the centering in good light, and if you are thinking about a submission, price the whole process first with our grading cost calculator — for a fresh pull in clean shape it is often worth the fee, but not at every service tier.
Which product should you buy?
Chaos Rising gets the full standard product lineup: 36-pack booster boxes, Elite Trainer Boxes and booster bundles. Because the set is small and its value is concentrated in a handful of cards, the per-pack price matters more than usual — overpaying per pack in a set with one dominant chase card is the classic way to end up disappointed. Run whatever deal you find through our price-per-pack calculator, and read our booster box vs ETB vs bundle guide if you are unsure which format suits you. Before committing to a box, glance at the Chaos Rising pull rates to calibrate expectations: a typical box delivers a solid stack of hits, but the Greninja SIR is a genuine long shot in any single box.
Verdict: who is this set for
Chaos Rising is for Greninja fans first — if that SIR is your grail, nothing else in 2026 scratches the same itch — and for collectors who enjoy small, focused sets where every rare slot feels relevant. Players get real tools in Mega Gallade ex and the disruption package around it. Who should skip it? Anyone opening packs hoping for a broad, deep set full of chase cards; that description fits Mega Evolution (ME01) far better. And if you only want one or two specific cards, check the singles prices first — in a set this concentrated, buying the card you want is very often cheaper than hunting it in packs.
