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.
