The Pokémon TCG Mega Evolution Chaos Rising Build & Battle Box (ME4) launched May 22, 2026, giving players a ready-to-play 40-card deck, four Chaos Rising booster packs, one of four foil promos, and a Pokémon TCG Live code card. The underlying Chaos Rising expansion carries a strong secret rare layer headlined by multiple Mega ex Special Illustration Rares and a Mega Hyper Rare, which is what makes even an entry-level product like this worth cracking.
What's In The Box
Each Build & Battle Box contains one 40-card ready-to-play deck, four Chaos Rising booster packs, one of four foil promo cards, and one Pokémon TCG Live code card.
The Checklist
Chaos Rising (ME4) contains at least 122 cards: 86 in the base set and 36 secret rares. The set centers on Mega Evolution mechanics, bringing Mega Greninja ex, Mega Dragalge ex, Mega Floette ex, and Cinccino ex into the spotlight across multiple rarity tiers. The secret rare layer is dense enough that the top of the set carries real collector weight.

What It Costs
The Build & Battle Box retails at $69.99. The Chaos Rising Build & Battle Display Case is trading on the secondary market around $348. On the singles side, Mega Greninja ex SIR (#116) is currently at approximately $160, making it the clear value anchor for the set.
Why Collectors Care
Mega Evolution is a mechanic with deep nostalgia pull, and Chaos Rising is the first ME4 expansion to give Mega Greninja ex the full Special Illustration Rare and Mega Hyper Rare treatment simultaneously. A $69.99 Build & Battle Box is a low-friction entry point into a set where the top singles are already trading at meaningful prices, which means the pull math is at least worth running.
What To Watch After Launch
Watch the Mega Greninja ex Mega Hyper Rare (#122) closely as more sealed product gets opened and supply becomes clearer. If the SIR holds above $150 with volume, the Hyper Rare has room to move significantly higher.
