Unlucky Cabbage Merchant [Avatar: The Last Airbender]

When this creature enters, create a Food token. (It's an artifact with "2, T, Sacrifice this token: You gain 3 life.")
Whenever you sacrifice a Food, you may search your library for a basic land card and put it onto the battlefield tapped. If you search your library this way, put this creature on the bottom of its owner's library, then shuffle.
