Zarghoza, Voidwalker

{1}: Exile target card from anyone's graveyard.
You may play any card in exile. Spells on the
stack and cards on battlefield that were cast from
exile each get a divinity counter. If a spell or
permanent with a divinity counter on it would be
exiled for any reason, shuffle it into its owner's
library instead, and you may gain 1 life.
You may activate any ability of any card on the
battlefield, in any graveyard, or in exile.
