I LOVE
Agent of the Dark Lord, as he's so versatile and a steal for 4 build (I think he's one of the best "starter/fixed" cards in the game) and have decks that use him. My deck is a revision where I wasn't careful enough to remove
Radagast Decieved, but you're totally correct in that he serves no function here! D'oh!
I like your deck and will have to give it a try when I branch out into Hunters territory. Even though
AotDL can be wicked-effective, I don't think
Servant of the Eye is a TOTAL loss in comparison. He doesn't just potentially assign himself, as you say, but if he doesn't manage to assign you've thrown a lot of exertions around (yes, some decks can take advantage of this, say with
Strength of Spirit and
Gandalf's Staff, Ash Staff, but that's hardly a reason not to run the deck). My deck is based on slowing down the FP's player and/or killing characters with wounds, a purpose helped along by
Servant of the Eye's forced exertions and damage bonuses with the staff and throne.
Desertion is also nice for an occasional overwhelm. It's a fun deck to play, and uses lots of cards that aren't seen too often. Its two biggest weaknesses I see are archery and healing. I'm hesitant to run
Spies of Saruman because it's such a dead card against many opponents and this deck doesn't have much cycling.
