Certainly nothing exciting in these guys. There are 6 different miniatures made up of 2 variations of 3 basic poses. I lack the tree men to really field this team with just two in total but even if I had them they would be pretty low on the list. I would probably do goblins first as they at least get the secret weapons which can be fun if not really effective.
Here is the Third edition Treeman Star Player. Since Halflings generally have a lot in inducements you generally will have 2 tree man plus the tree man star.
