The 10 most expensive Pokémon cards of Ultra Prism (Chase Cards)

Prism Star cards debut on February 2, 2018, carrying a diamond symbol as part of the card name and limited to a single copy per deck: any that would reach the discard pile is sent to the Lost Zone instead, so it is normally played once and never seen again. Six appear here, on black borders whose artwork window is edged in rainbow. Sinnoh arrives with them through Ultra Space, in Dialga-GX and Palkia-GX and in Supporter cards for Cynthia, Gardenia and Mars, while Fossil Pokémon go back to their older rule and hatch from a Trainer card that doubles as a Basic Pokémon on the field.
