All playtest-cards must be printed on cardstock of the appropriate thickness and dimensions, ensuring they match the original cards in your library. Playtest cards must also be in color. Additionally, please ensure that your proxies are printed with original WotC art and a resolution that facilitates easy readability for both fellow players and judges. Gold-bordered cards can be used as playtest cards.
