Call of the Citadel

When Call of the Citadel enters, you gain 3 life.

At the beginning of your upkeep, reveal cards from the top of your library until you reveal a land card. Put that card into your hand and the rest on the bottom in a random order.

At the beginning of your upkeep, if you control a Plains, Island, Swamp, Mountain, and Forest, transform Call of the Citadel.
