Consecrated Vessel

Infect (This creature deals damage to creatures in the
form of -1/-1 counters and to players in the form of
poison counters.)
When Consecrated Vessel dies, proliferate, then
you gain 2 life for each -1/-1 counter and poison counter placed this way. (Choose any number of permanents and/or players, then give each another
counter of each kind already there.)
A pilgrimage of disease across a tainted world.
