Daughter of Innocence

When Daughter of Innocence enters the battlefield, look at the top 4 cards of your library.
Exile one face down, then shuffle the rest into
your library. When Daughter of Innocence dies,
if the exiled card is a nonland permanent, you
may cast it without paying its mana cost if its
converted mana cost is greater than or equal to
your life total. Otherwise, put it into your hand.
