To End the Impossible Dream

When To End the Impossible Dream enters, create a
Blood token. (It's an artifact with "{1}, {t}, Discard a
card, Sacrifice this artifact: Draw a card.")

Sacrifice a Blood token: Prevent the next 3 points of
damage that would be dealt to you this turn.

{3}{w}{w}, Sacrifice To End the Impossible Dream: Return
target creature card from your graveyard to the
battlefield with a finality counter on it. (If a creature with
a finality counter on it would die, exile it instead.)
