I had a dwarf paladin that used the tree token to take out a flying/invisible sorcerer of death. It took us a couple of rounds to collectively identify his location and then acivate the tree token. It was fun because neither the other players nor the DM knew what we were going to do once we were able to find this guy, so they were all pretty surprised. The DM had to make up some rules on the spot regarding what happens when a tree appears in the middle of a flying guy, and I know he was pretty messed up after that.
It's certainly my favorite token.
