Pokémon TCG: Mega Evolution—Chaos Rising Build & Battle Box

Pokémon TCG: Mega Evolution—Chaos Rising Build & Battle Box is a sealed Chaos Rising product. Chaos Rising is the fifth Mega Evolution expansion, released May 2026, and its sealed launch cycle saw Elite Trainer Boxes and Build & Battle Boxes sell through first, with Booster Bundles and Triple Packs restocking most often since. The set's top cards include Mega Greninja ex in Special illustration rare and Mega Hyper Rare, Cinccino ex, Mega Dragalge ex, Mega Floette ex and AZ's Tranquility, all Special illustration rare.

What comes in the box

• 4 booster packs
• A 40-card ready-to-play deck
• One of four promo cards

The Build & Battle Box pairs 4 booster packs with a ready-to-play deck and a promo card, while the Booster Bundle offers 6 packs with no accessories and the Elite Trainer Box carries 9 packs with sleeves, dice and a storage box. It sits between the Triple Pack's 3 packs and promo and the larger sealed configurations in pack count.

That is the retailer's list price — these posts are restocks, not markdowns. Of the 90 other Pokémon listings tracked right now, 45 are cheaper.

What makes it worth opening is the set rather than the box: Chaos Rising is chased for Mega Greninja ex, and the full list sits in the set guide below.

This is a price record, not a pull report. We do not open sealed product, so nothing here describes what came out of a box. Sealed prices move quickly on cards, and the figure above is the one the monitor read when it posted on 7 October 2026.
