Pokémon TCG: Mega Symphonia (M1S) Booster Box – Japanese

Pokémon TCG: Mega Symphonia (M1S) Booster Box – Japanese

Thirty packs. A new golden rarity. The Mega Gardevoir ex MUR as the marquee pull. One of two launch sets of the Japanese Mega Evolution era.

Mega Symphonia is one half of the Japanese Mega Evolution era launch alongside its sister set Mega Brave, and the Japanese counterpart to the English Mega Evolution base set. Released August 1, 2025, this is the set that introduced the MUR (Mega Ultra Rare) rarity to the Pokémon TCG, a single golden-holo card per set that sits above all existing rarities. Mega Gardevoir ex headlines both as the MUR and as an SAR. As a launch pillar of the Mega Evolution era, sealed Mega Symphonia boxes are a natural cornerstone hold.
