Mega Diancie

Mega Diancie is the Mega Evolution of Diancie, a Rock/Fairy-type Pokémon. Mega Evolving keeps its Rock/Fairy typing while it sharply raises its stats for the duration of a battle.

“It can instantly create many diamonds by compressing the carbon in the air between its hands.”

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 Diancie ex cards in the Scarlet & Violet "Mega Evolution" era — both of which are among the most chased pulls of their sets.

Chase Season tracks 4 Mega Diancie cards across 3 sets, with daily market prices and Chase Index rankings. The most valuable right now is Mega Diancie ex from Ascended Heroes at around $73.15.
