Cloud
Cloud is a basic land type that was added to the five regular ones (Plains, Island, Swamp, Mountain, and Forest) when the Mystery Booster set was released. It provides colorless mana, which may be used to pay generic mana costs.
Cloud is not legal for Constructed play. It only appears on a test card (Barry's Land).[1]
