Lich

As Lich enters the battlefield, you lose life equal
to your life total. You don't lose the game for
having 0 or less life.
If you would gain life, draw that many cards
instead. Whenever you're dealt damage,
sacrifice that many nontoken permanents.
If you can't, you lose the game. When Lich is put
into a graveyard from the battlefield, you lose
the game.
