I like using Gollum because I am only focussing on adding burdens. In that respect her helps soak up archery against elf decks, also once 3 burdens are on the ringbearer he becomes a very effective fighter. He benifits from people that use the water ring, and he can bring back easterlings to add more burdens.
The fact that my shadow is only trying to add burdens is key. I am not trying to get my minions to be fierce and damage plus 1, I just want to add the burden and move on. The Captain does help but I would replace him with another minion that adds burdens if I could!
The Hobbits are usually expendable after site 5 once all of my stealths become useless. I guess it couldn't hurt to try and use the common ones as another way to cancel skirmishes. To be honest, I am not even sure why I have Treebeard in the deck. The amount of times I have used him with the hobbits can be counted on two hands.
It's been a fun deck to play, and I appreciate any reviews that are given. It's fun to see how others would play this type of deck.
