Parasitic Fungus

Lifelink, Reach
At the beginning of an opponents upkeep,
you may pay {1}{b}. If you do, that opponent loses 1 life and you gain 1 life. Whenever
this ability is activated, put a +1/+1 counter on Parasitic fungus.

"Stay out of the swamp unless you want to
pick up a fungus. We can only remove them through amputation."
-Jorvid, village Medicine Man.
