Lifestream's Blessing

Draw X cards, where X is the greatest power among creatures you controlled as you cast this spell. If this spell was cast from exile, you gain twice X life. Foretell {4}{G} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
