M Master Deck Build Box Power Style Card List

M Master Deck Build Box Power Style is a Japanese Pokémon TCG deck product from the XY era, released on August 7, 2015 under the set code MMB. It is a compact release with 58 catalog printings. The headline cards define it: Mega Gengar EX leads the card list, with Gengar EX, Charizard EX, Primal Groudon EX and Groudon EX close behind. That makes it a box built around Mega and Primal evolutions and the EX Pokémon that lead into them, rather than a broad expansion.
