Pokémon Chaos Rising – Sleeved Booster

We don't have this in stock right now. See Boosters & packs for what we have in stock.

Sleeved booster from Pokémon Mega Evolution—Chaos Rising (ME04), English edition released on 22 May 2026.

Chaos Rising is the fourth expansion of the Mega Evolution era and is led by Mega Greninja ex, alongside Mega Pyroar ex, Mega Floette ex, Mega Dragalge ex and Mega Gallade ex. The set is translated from the Japanese release Ninja Spinner but has three English additions not found in the original, and the top of the rarity ladder is a Mega Hyper Rare of Mega Greninja ex.

A sleeved booster is the same pack found in the display, but delivered in an extra plastic sleeve with a hang tab. The sleeve is there for the store shelf and protects the pack during shipping; the card contents are identical to a regular pack from the set. Mega Evolution Pokémon ex have higher HP and harder-hitting attacks than regular Pokémon ex, but your opponent takes three Prize cards instead of two when they are knocked out: the whole era is built around that trade-off.

For those who want a single pack in undamaged condition, or to put one in a gift. The artwork on the sleeve varies and cannot be chosen. Worth knowing: the three English additions are not in the Japanese Ninja Spinner release, so the sets are not interchangeable. The contents of each pack are random and cannot be chosen. English edition with English text on both packaging and cards. The image shows one of the variants.
