What Is Chaos Rising?

Chaos Rising is the fourth English-language set in the Mega Evolution series (set code ME4). It's based on the Japanese Ninja Spinner set, with three English-exclusive additions, the most notable being Mega Gallade ex, sourced from January's Mega Gallade ex Special Set in Japan.

The set contains over 120 cards. The headline pulls are Mega Greninja ex, Mega Floette ex, Mega Pyroar ex, and Mega Dragalge ex. TCG Watchtower singles out Mega Greninja ex as the most anticipated pull in the set, which will likely drive pack prices on the secondary market once we're past the 22 May release.

There's also narrative cross-promotional relevance. Mega Floette ex is tied to Pokémon Legends: ZA, described as wreaking havoc as night falls in Lumiose City. Whether that drives demand depends on how the game lands with players, but it's worth noting for collectors tracking cross-media momentum.

Build & Battle Events: What to Expect

If you've not done a prerelease event before, here's what to expect. A Build & Battle Box contains four booster packs and a 40-card prerelease kit with a stamped promo card. You use those cards to build a 40-card deck on the spot and play a few rounds against other players at your local store. It's casual, beginner-friendly, and typically costs around £5–£15 depending on the store, though entry prices vary by venue.

Events run today through 17 May 2026. To find your nearest participating store, use the Play! Pokémon Event Locator on the official Pokémon website. Filter by your postcode and select Build & Battle. Spaces are usually limited, so if you want to play, contact your local store today to confirm availability.

The promo card you receive at prerelease is stamped with a special prerelease stamp. These have some collector value but aren't typically high-demand singles, depending on which card is included.

The Products: What's in Each Box

No UK retailer has confirmed GBP pricing as of 9 May 2026. For context, standard ETBs in the Mega Evolution series have historically landed around £45–£55 at most UK retailers, and booster boxes in the £100–£130 range, though Chaos Rising pricing may vary. Expect UK listings to appear in the coming days ahead of the 22 May release. If you spot a UK listing, check it against those reference points before committing.

Chaos Rising Pull Rates: What We Know (and Don't)

Pull rate data for Chaos Rising does not exist yet. The set only entered prerelease today, 9 May 2026. Anyone publishing pull rate percentages right now is either fabricating them or extrapolating from the Japanese Ninja Spinner set, which is a reasonable proxy but not confirmed for the English print run.

The Japanese rarity structure from Ninja Spinner gives a rough framework. Special Illustration Rares and Hyper Rares in Japanese sets of this size typically land at roughly one per two to three booster boxes, though English print runs have historically varied. Once the community starts opening boxes on and after 22 May, pull rate data will emerge quickly on sites like Limitless TCG and through community tracking on r/PokemonTCG.

We'll update this article with confirmed English pull rate data as it surfaces post-release.

Chase Cards: What to Watch

Five cards are worth tracking from a collector and competitive standpoint:

• Mega Greninja ex: The marquee pull. Water-type with strong competitive pedigree for the archetype and the face of the standard ETB. Expect this to command the highest singles price at launch.
• Mega Floette ex: Fairy-type with Pokémon Legends: ZA narrative tie-in. Could have speculative collector demand depending on how the game is received.
• Mega Pyroar ex: Fire type, solid mid-tier hype. Worth watching if Fire decks see competitive play post-rotation.
• Mega Dragalge ex: Dragon and Poison typing. Niche competitive potential but strong collector interest given the unusual type combination.
• Mega Gallade ex: English-exclusive promo. Not in the Japanese Ninja Spinner set. This is the most interesting card for collectors who track what's unique to the English print run.

Pokémon Center ETB: Worth It?

The Pokémon Center exclusive ETB gives you 11 packs versus the standard nine, plus two full-art Fennekin promos. Whether that's worth the premium depends on what Pokémon Center charges for it, which isn't confirmed yet.

If the price difference over the standard ETB is £8–£12, the two extra packs alone justify it at typical UK pack prices. The Fennekin promos add collector value on top. If the premium is higher than that, you're paying for exclusivity as much as product content.

Stock on Pokémon Center exclusive products tends to move quickly. Set a reminder for 22 May and check the Pokémon Center UK site early if you want one.

What to Do Now

If you want to play prerelease, today is day one. Find your nearest Build & Battle event via the Play! Pokémon locator, confirm with the store that they have spaces, and register. It's a good format for newer players and a cost-effective way to get your hands on Chaos Rising packs before the general public can buy them.

If you're buying sealed product to open, hold off on paying secondary market prices for booster boxes until UK RRP is confirmed. UK retailers should be listing Chaos Rising stock in the next few days ahead of the 22 May release.

If you're buying singles, wait until after 22 May. Launch week pricing on new sets is almost always inflated. Mega Greninja ex will almost certainly be cheaper two weeks post-release than it is on launch day, unless it immediately dominates a tournament. Watch the results from the first major events after release before spending significant money on singles.
