Arasiph, Seraph of Mercy

When Arasiph enters the battlefield, return all creatures from the graveyard back under their owners control, return all creatures to their owners control, prevent all damage that would be dealt this turn, and return your life total to your starting life total.
As long as Arasiph is in play, other creatures you control cannot be destroyed, sacrificed, or exiled.
