Lich's Phylactery

You don't lose the game for having 0 or less life.
At the beginning of your upkeep, put a
phylactery counter on Lich's Phylactery.
Whenever you are dealt damage while you have 0
or less life, remove a phylactery counter from
Lich's Phylactery. Then, if there are no
phylactery counters on Lich's Phylactery,
sacrifice it.
