Patient 0

{w}{b}: Patient 0 gains Menace until end of turn.
Whenever a creature dealt damage by Patient 0
dies this turn, you and that creature's controller
each create a 2/2 black Zombie creature token
with Menace.
During each player's upkeep, that player loses life
equal to the number of creatures with Menace
they control.
Patient Zero's power and toughness are equal to
the number of Zombies you control.
