Grave Conclave
Artifact Land (Rare)

(Grave Conclave isn't a spell.)

When Grave Conclave enters the battlefield, return a land you control to its owner's hand.

Grave Conclave is indestructible. (Destroy effects and lethal damage don't destroy it.)

Tap, Pay 1 life, Sacrifice Grave Conclave: Search your library for a Island or Swamp card and put it onto the battlefield, then shuffle your library.
