The 10 most expensive pokemon cards of XY (Chase cards)

Released on February 5, 2014, XY is the inaugural expansion of the XY series, introducing the Mega Evolution mechanic to the Pokémon Trading Card Game alongside the Fairy type as a brand-new TCG type. The set features the Kalos region's starter Pokémon and powerful Pokémon-EX including Mega Venusaur-EX, Mega Blastoise-EX, Xerneas-EX, and Yveltal-EX — the latter becoming one of the most dominant competitive cards of the entire XY era. As the foundation of a new generation that brought modernized card design, Mega Evolution, and the Fairy type to the game, XY established the framework that would define the TCG for years to come. Here are the 10 most expensive cards from this expansion.
