Altrazian Elemental

Captain - This card must be your commander. Before the game starts, set aside any number of basic lands with land types.

Eminence - All your Wastes have: "{c}{c},{t}, Sacrifice this land: Chose 1 basic land that was set aside with Altrazian Elemental and put it into the battlefield."

Whenever a basic land enters the battlefield from outside the game, you can search your library for a creature that shares a color identity with that land and add it to your hand. Shuffle your library.
