THE BEST OF XY is a subset in the Pokémon Card Game Sun & Moon Era in Japan. It was released on April 21, 2017.
THE BEST OF XY focused on Pokémon-EX, M Pokémon-EX, and Pokémon BREAK and included various reprints of popular cards from the XY and XY BREAK Eras, while also including a number of new cards and Full Art prints. Despite being released during the Sun & Moon Era, the cards are printed with their original card template, with only a slight change in the positioning of the card number, and the lack of printed rarities. All the regular cards included within the subset also had a Reverse Starlight Holofoil print. Each pack contained fifteen cards instead of five, guaranteeing one Pokémon-EX, M Pokémon-EX, or Pokémon BREAK, as well as one Reverse Starlight Holofoil card.
