Pokémon TCG Chaos Rising: release date, Mega Greninja ex, and Chaos Rising pre orders UK

If you have ever tried to pick up the latest Pokémon TCG set on release day, you already know the struggle. The minute products go live, bots and scalpers pile in, and suddenly everything is sold out and you are scrambling to find anything at a sensible price. Chaos Rising is the next set generating serious interest in the community for one simple reason: it is strongly believed to be the English set that brings Mega Greninja ex into the spotlight.

Important: while the set name and dates are being widely reported, Pokémon has not published the full official product lineup yet. That means details can change leading up to release. When Chaos Rising pre orders go live at OBSIDIA, you will find them here: Pokémon TCG: Chaos Rising.

Pokémon TCG Chaos Rising release date and pre-releases

The dates being reported right now are straightforward: Chaos Rising is expected to release on 22 May 2026, with prerelease events running from 9 May to 17 May.

If you have done prerelease weeks before, you already know why those dates matter. It is the first moment people can actually get hands-on with the set, and it is usually when hype turns into a proper rush. If you want to avoid the last-minute scramble, do the boring bit early. Decide what you want to preorder, and check in around early May rather than waiting for release week.

Why Mega Greninja ex is the headline everyone is talking about

Greninja is one of those Pokémon that never really cools off. It has the look, it has the fanbase, and it always seems to get artwork that makes people scream. If the leaked artwork and early reports are accurate, Mega Greninja ex is going to be the card a lot of people are chasing in Chaos Rising. I am not even pretending this is complicated for me. If Mega Greninja ex is real for Chaos Rising, it is instantly the number one card I want from the set.

The collector brain goes straight to the same question every time: are we going to see a premium chase rarity for Greninja, like a gold-style card? Nothing is confirmed, but it is exactly the sort of detail people watch for once official reveals start landing.

The other factor is playability. If Mega Greninja ex is even slightly strong in decks, prices can climb quickly, especially early on when supply is tight. If you pull it, are you the type who holds it for the collection, or do you sell into the early demand while the hype is at its peak?

Chaos Rising products and pack counts

Until Pokémon publishes the official Chaos Rising product lineup, the most useful thing we can do is stick to the formats that show up in most modern English releases, and include the pack counts that actually help you plan a preorder.

Important: the pack counts below are typical for recent English releases. Chaos Rising details may change once official product pages are live.

Chaos Rising Elite Trainer Box (ETB)

The classic all-in-one set box. A modern ETB typically includes 9 booster packs, plus sleeves, energy, dice, and a player’s guide.

Chaos Rising booster box

The main sealed display product for a standard set. A booster box typically includes 36 booster packs. This is the one collectors pick when they want a bigger opening, or when they want a sealed box that looks good on the shelf.

Chaos Rising booster bundle

A packs-only option that sits nicely between “a couple of packs” and a full box. Booster bundles typically include 6 booster packs.

Chaos Rising booster packs

The everyday entry point. A standard booster pack is 1 pack. Sleeved boosters are still 1 pack, just packaged for hanging displays.

Chaos Rising blisters

These usually show up as single-pack blisters (1 pack) and 3-pack blisters (3 packs). They are a nice way to keep openings smaller and more paced.

Chaos Rising prerelease products (if confirmed)

If prerelease products are confirmed for Chaos Rising, Build and Battle style boxes typically include a 40-card ready-to-play deck plus 4 booster packs. These are aimed at early play and early openings during prerelease weeks.
