Hecarim of the Elderwood

Trample
At the beginning of your upkeep, put a +1/+1
counter on Hecarim of the Elderwood.
Whenever you tap a forest for mana, you may
remove a +1/+1 counter from a creature you
control. If you do, add an additional {g}.
"...Even now, Hecarim travels the shallow rivers and
moss-flecked paths of the Elderwood, that ageless
guardian who protects the forest from mankind's
darkest yearnings."
