The Mega Symphonia m1S Booster Box is a significant product from the Pokémon card series, specifically designed for the Japanese market. This booster box contains a total of 30 booster packs, each including 5 cards. The cards in this set are part of the new Mega Evolution ex series, which was introduced during the Japan Championships 2025. The Mega Evolution ex cards feature a special texture and sparkling effects reminiscent of the existing Tera ex cards. Unlike previous Mega ex cards, which typically represented the final evolution of a Pokémon, the new cards in this set are designed as Stage 2 and evolve from their pre-evolutions. This offers collectors and players an expanded opportunity to build their decks and play strategically.
