Pokémon TCG: Mega Evolution marks the first expansion in the upcoming Mega Evolution Series, which will feature the highly anticipated return of Mega Evolution Pokémon to the Pokémon TCG. These mighty Pokémon first appeared in the Pokémon TCG in the XY Series and were last seen in the Sun & Moon Series. In the Mega Evolution expansion, players will be able to discover and collect cards featuring powerful Mega Evolution Pokémon ex, including Mega Lucario ex and Mega Gardevoir ex.

Though powerful and equipped with increased HP and attack damage compared to regular Pokémon ex, Mega Evolution Pokémon ex will give up three Prize cards when Knocked Out. In addition, Mega Evolution Pokémon ex appear as Basic Pokémon, Stage 1 Pokémon or Stage 2 Pokémon and do not require an extra Evolution step (for example, Mega Lucario ex evolves from Riolu, rather than from Lucario).

Players can also look forward to discovering a new art style for ultra rare Mega Evolution Pokémon ex, which may feature a silhouette of the regular version of that Pokémon (for example, Lucario appears in silhouette on the ultra rare card featuring Mega Lucario ex). Furthermore, Mega Evolution will expand ultra rare cards beyond Pokémon and Supporter cards, with the introduction of ultra rare Item, Stadium and Pokémon Tool cards.
