Enchant land
Enchanted land is a Swamp.
Illus. Sandra Everingham

10/1/2009: The enchanted land loses its existing land types and any abilities printed on it. It now has the land type Swamp and has the ability "{T}: Add {B} to your mana pool." Evil Presence doesn't change the enchanted land's name or whether it's legendary, basic, or snow.
