one of the problems with a deck such as this is that, first, it requires winning skirmishes with the assassin in play, and then, when that finally does happen, the ringbearer can absorb wounds as burdens no matter what ring hes wearing, because it will be during the skirmish phase.
plus, you only get 1 wound per win. all in all, i doubt that you can make a killer deck around it, but you might be able to use it as a side strategy.
