Lich

As this enchantment enters, 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 this enchantment is put into a graveyard from the
battlefield, you lose the game.
