This PSA10 Mega Gengar ex card is a noteworthy piece from the Pokémon Trading Card Game, which has seen significant popularity since its debut in 1996, particularly with the Mega Evolution mechanics introduced in Pokémon X and Y.

Gengar, as a fan-favorite ghost-type Pokémon, consistently drives collector demand, especially in limited-edition releases like this one.

The card's pristine condition, verified by PSA grading, enhances its desirability within the Japanese collector market, where properly stored, first-run cards are highly sought after.

Collectors often prize unique traits such as one-owner submissions, making this card particularly appealing for those looking to expand a curated portfolio with authentic Japanese collectibles.
