Shivan Wumpus

Creature - Beast 6/6, 3R (4)
Trample

When Shivan Wumpus enters the battlefield, any player may sacrifice a land. If a player does, put Shivan Wumpus on top of its owner's library.¹
It's easier to move the village than to divert the wumpus.

If he or she declines, the next player in turn order gets the option.  If a player elects to sacrifice a lang, this is put on top of its owner's library, but then all remaining players still get the option. If all players decline, then nothing happens and Shivan Wumpus stays on the battlefield.
