Bug: can't put more than one Wastes in an EDH deck

{"ops":[{"insert":"Really liking this site! I'm in the process of importing some of my decks over.\nI was loading a Kozilek deck and noticed that it threw an error \"You may only have one copy of a card in a commander format - Wastes\". It should be legal since Wastes are a basic land.\n\n"}]}
