Terrains des charognards

Desert is a land subtype with no special meaning. It doesn't grant the land an intrinsic mana ability. Other cards may care about which lands are Deserts.

If a Desert has an ability with a cost of "Sacrifice a Desert," you can sacrifice that Desert to pay the cost for its own ability.

The sacrificed Desert will be in your graveyard to be exiled by the last ability of Scavenger Grounds.
