Tanaan Headhunters

Forestwalk, Swampwalk (This creature can't be
blocked as long as defending player controls a Forest
or a Swamp.)
Whenever a creature an opponent control dies,
put a +1/+1 counter on Tanaan Headhunters.
The orcs of the Bleeding Hollow Clan were dark allies
long ago... and even darker enemies now.
