Checking through the Free people book (they need to release Captured people, the paralyzed hobbit models don't have any rules at the moment) I came upon the following possible army:
Short of using Floi who can ignore rules, how would you deal with this, Tom can lock anything scary up and both he and goldberry can heal the extremely hard to kill Durin each turn. Durin can then pick of your models one after one until you are broken at which point Bombadil and Goldberry chose to stand next to him and make him untouchable.
So I challenge you, make a 500pts list to kill this one (thatīs 40pts over this list).
List should be included as well as a description on how it kills the unkillable.
