Prophet of Dust

If you would draw Prophet of Dust, instead you may pay {5}{w}{w} and reveal it. If you do, exile it, then draw a card, and for each player, exile two target lands of that player's choice.
Whenever Prophet of Dust attacks, you may pay {3}{w}{w}. If you do, for each player, exile target land of that player's choice.
When Prophet of Dust dies, you may search your library for a card named Prophet of Dust, shuffle your library, and put that card
on top of it.
