Adiris, the Plague

Infect (This creature deals damage to creatures in the form of -1/-1 counters and players in the form of poison counters.) Adiris gets +1/+1 for each creature with a -1/-1 counter on it. When a creature with a -1/-1 counter on it dies, Adiris gains deathtouch until the end of your next turn. If a -1/-1 counter would be put on Adiris, put a +1/+1 counter on her instead.
