Eldritch Unlife

You don't lose the game for having 0 or less life & you can nolonger spend life points.
As long as you have 0 or less life, all damage
dealt to you will now put that many unlife counters on this card. If this has 13 or more unlife counters on it, you must sacrifice this enchantment or sacrifice X+1 permanents
to remove X unlife counters from it instead.
