Another Yawgmoth Card

Whenever a spell or ability you control causes
you to lose life, put three +1/+1 counters on
Yawgmoth.
You don't lose the game for having 0 or less life.
As long as you have 0 or less life, all damage is
dealt to you as though its source had infect.
(Damage is dealt to you in the form of poison counters.)
