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.
