Mega Evolution debuted in Pokémon X & Y (2013) as a temporary, in-battle transformation. In the Pokémon TCG it appears first as “M” Pokémon-EX cards in the XY era, and again as Mega Gengar ex cards in the Scarlet & Violet "Mega Evolution" era — both of which are among the most chased pulls of their sets.
Chase Season tracks 6 Mega Gengar cards across 3 sets, with daily market prices and Chase Index rankings. The most valuable right now is Mega Gengar ex from Ascended Heroes at around $1,311.99.
