A "High Class Pack" series, Mega Dream ex is the very first end-of-year set for the Pokémon TCG, meant to revisit some of the most significant cards of the past couple of years. The expansion is especially focused on Pokémon of the Mega Evolution ex variety, which makes it also a subset of the ongoing Mega Series.
Each booster box contains 10 booster packs. Each pack contains 10 cards. All cards are in Japanese.
