You may play an additional land on each of your turns. Lands you control are every basic land type in addition to their other types.

Landfall — Whenever a land enters the battlefield under your control, add one mana of any color. Then if this is the second time this ability has resolved this turn, reveal cards from the top of your library until you reveal an Elf or Elemental card. Put that card into your hand and the rest on the bottom of your library in a random order.

Sacrifice a land: Target creature you control gains shroud until end of turn. (It can't be the target of spells or abilities.)
