Anatos, Titan Of Life's Voice

When Anatos enters the battlefield, sacrifice it
unless it escaped.
Whenever Anatos enters the battlefield or attacks,
look at the top three cards of your library. You
may reveal a creature or enchantment card from
among them and put it into your hand. Put the
rest on the bottom of your library in any order.
Escape—{g}{g}{w}{w}, Exile five other cards from
your graveyard. (You may cast this card from
your graveyard for its escape cost.)
