About the Mega Evolution era
Mega Evolution is the current English block, and this collection brings its expansions together in one place: Ascended Heroes, Phantasmal Flames, Chaos Rising and Perfect Order, so you can compare releases without hopping between pages.
Formats vary by expansion. Some get a full booster box, others lead with Elite Trainer Boxes, booster bundles, tins or collection boxes. Each listing states the exact contents and current availability, and the booster box vs ETB vs booster bundle guide explains which format gives you what.
