Destruction of Isengard

Destroy target artifact or enchantment.
Awaken 4 -{3}{g} (If you cast this card for {3}{g}, also put four +1/+1 counters on target land you control and it becomes a 0/0 Ent creature. It's still a land.)
After Treebeard's Stewardship over Isengard ended, nature fully took over.
