Night falls on Lumiose City — and chaos is about to bloom. The Pokémon TCG: Mega Evolution — Chaos Rising Elite Trainer Box is the definitive way to experience the fourth chapter of the Mega Evolution block, and one of its most dramatically conceived and narratively charged sets yet. The city that defined the Kalos region is under threat — and the Pokémon who answer the call are among the most powerful Mega Evolution Pokémon ex ever printed.
The story begins with Mega Floette ex — a Fairy-type force of nature that has blossomed into a dangerous agent of chaos, unleashing havoc across the bustling streets of Lumiose City. In response, Mega Greninja ex rises to meet the threat, gathering a fearsome coalition of Mega Evolution Pokémon ex to push back against the growing darkness. Mega Pyroar ex and Mega Dragalge ex stand alongside Greninja in a lineup that represents the most thematically cohesive and most narratively driven set in the entire Mega Evolution series — a genuine clash of forces set against the iconic backdrop of one of the Pokémon world's most beloved cities.
Chaos Rising introduces a landmark new gameplay mechanic — the Unstable Evolution rule. When you evolve into a Mega Evolution Pokémon ex, your turn does not end. Instead, you flip a coin — heads and the evolution is successful, allowing you to continue your turn as normal and unleash your Mega Evolution's full power immediately. Tails and the evolution is disrupted, with consequences that make every Mega Evolution an act of genuine risk and drama. It is one of the most exciting and most genuinely unpredictable mechanics introduced to the Pokémon TCG in years, and it makes every game featuring Mega Evolution Pokémon ex feel entirely different to what has come before.
The set spans over 120 cards featuring new Mega Evolution Pokémon ex, Trainer's Pokémon, Special Illustration Rares and the brand-new Mega attack rare subset — featuring attack names in Japanese katakana — that has become one of the most collected and most visually distinctive rarity types in the entire Mega Evolution series. With Mega Greninja ex and Mega Floette ex leading a checklist of debut Mega Evolution Pokémon ex, the pull potential across all nine booster packs is as strong and as exciting as any set in the block.
The Elite Trainer Box is the most complete and best value single product in the Chaos Rising lineup — nine booster packs, a full accessories suite and an exclusive full-art foil promo card featuring Fennekin, the beloved Kalos Fire-type starter, making this box as compelling for collectors as it is for competitive players.
Released globally on 22 May 2026 — the most anticipated Mega Evolution release since Ascended Heroes.
