Thirty-six packs at £154.44 RRP. Chaos Rising is a small set at 86 cards in the main run and 122 in total, so a full box represents a serious attempt at completing it rather than a sample of a much larger pool, which is the main argument for buying at box level here rather than in bundles. Mega Greninja ex is the card the set is built around and by some distance the one driving demand, with Mega Floette ex, Mega Pyroar ex, Mega Dragalge ex and Mega Gallade ex making up the rest of the Mega Evolution ex lineup. Greninja has a long history of pulling more interest than its rarity alone would explain, which is worth factoring in when comparing box prices across the Mega Evolution sets. Released 22 May 2026, so sealed boxes are still normal retail stock rather than collector supply.
