At the beginning of each upkeep, all creatures you control gain flying until end of turn if a creature you control has flying. The same is true for fear, first strike, double strike, landwalk, protection, trample, and vigilance.

Near Mint Condition
A card in Near Mint condition shows minimal to no wear from shuffling or general play. Cards classified as Near 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.
