Kuni Prayer

As an additional cost to cast this spell, exile three lands you control from the battlefield.
Search your library for a card named Uli, Spirit of Judgment, Pele, Volcano Goddess, or Kamoho'ali'i, Shark of the Depths, and put it onto the battlefield. That creature gains haste until end of turn.
At the beginning of the end step, shuffle that creature into your library.
