Soul of Fanghorn

Suspend 4- {1}{g} (Rather than cast this card from
your hand, you may pay {1}{g} and exile it with 4 time counters on it. At the beginning of your upkeep, remove
a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)
Other green creatures you control have hexproof
if they haven't dealt damage this turn.
They call Treebeard 'Fanghorn', but he is not him.
