10/1/2008: This ability changes the targeted land's land types. It doesn't affect its name, its supertypes (such as whether or not it's legendary, snow, or basic), or its other types (if it's also a creature, for example). The ability will cause the land to lose all of its printed abilities and gain the ability "{T}: Add {B} to your mana pool."
