Mega Evolution—Chaos Rising Sleeved Booster Pack – Pokémon TCG

10 Cards Per Pack · Mega Greninja ex · Kalos Region Siege Theme

The hustle and bustle of the city turns into havoc as Mega Floette ex brings turmoil to the streets! Filled with courage and determination, Mega Greninja ex gathers other powerful Mega Evolution Pokémon ex, including Mega Pyroar ex and Mega Dragalge ex, to ward off this growing threat in the Pokémon TCG: Mega Evolution—Chaos Rising expansion.[citation:2]

Each sleeved Chaos Rising booster pack contains 10 randomized cards, plus a Basic Energy and a code card for Pokémon TCG Live.[citation:1] Released on May 22, 2026, this expansion features five Mega Evolution Pokémon ex, including Mega Greninja ex, Mega Floette ex, Mega Pyroar ex, and Mega Dragalge ex.[citation:2] The set introduces the “Unstable Evolution” mechanic, where evolving into a Mega Pokémon ex requires a coin flip—a high-risk, high-reward twist on Mega Evolution gameplay.[citation:2]

The sleeved booster format provides an extra layer of protection, as the cardboard sleeve guards against bends and tampering, making it a great choice for collectors who value pack freshness.[citation:2]

Why Chaos Rising Stands Out

Chaos Rising is the fourth set in the Mega Evolution era and is widely considered one of the most exciting expansions of the block, thanks to its dramatic narrative, stunning artwork, and high-value chase cards. The Mega Greninja ex Special Illustration Rare is the card that defines the set, with artist Susumu Maeya crafting a breathtaking three-card connected panorama across Froakie, Frogadier, and Mega Greninja ex.[citation:4] The gold-etched Mega Hyper Rare version is one of the hardest pulls in the entire Mega Evolution block.

With a “collector-friendly” set size of just over 120 cards, this expansion offers a higher concentration of rare hits, making each booster pack a thrilling opening experience.
