Victory In Undeath

Can be cast only after an Opponent has declared
attackers, and only if the declared attackers would
cause your life total to be equal to or less than 0.
Your life total cannot be less than 1 until the start
of your next turn. Return all cards in your hand,
Graveyard, that are Exiled, and all non-land Permanents on the Battlefield to your library, and shuffle. Draw 3 cards and exile the top 30 cards of your Library. These Exiled cards cannot be played for any reason. Skip your next Draw Phase.
