Anarchy of the Zhur-Taa

When you cast this spell, you may sacrifice a
creature. If you do, copy this spell and you may
choose a new target for the copy.
The owner of target nonland permanent shuffles
it into their library, then exiles the top card of
their library. If it's a land card, they put it onto
the battlefield. Otherwise, they may cast it
without paying its mana cost.
