Near Mint Condition
A card in Near Mint condition shows minimal to no wear from shuffling or general play. Cards classified as Neam Mint/Mint are generally indistinguishable from cards in an unsleeved deck of other Near Mint/Mint cards. Foils in this condition have little or no scuffing or clouding on the front and edges of the card.
