The first half of the Won't Get Fooled Again fellowship, which relies on getting Sméagol flipped to Gollum and leaving him that way. This deck brings Sméagol and gives him some nudges to turn on the heroes as quickly as possible. Full description of the combos are in the fellowship description, but here's some piloting tips specific for this deck.
Before Smeagol flips, his resources should help you play cards. Feel free to through archery damage on him (Just don't kill him!).To speed his betrayal, Firyal and Celduin Traveler can dig through the encounter deck faster, though Risk Some Light and Shadow of the Past are generally the most helpful in pulling a copy of Stinker.
Once gollum shows his true colors, the deck turns into a two hero secrecy deck. Strider, and Light of Valinor can go on Glorfindel and Erestor interchangeably, as both will let a hero quest without exhausting. Resourcefuls can give resources and Erestor will bring in a constant stream of cards. Erestor can be built into a defender with Cloak of Lórien, and A Burning Brand, along with Lembas to heal as well as defend multiple times.
Glorfindel can both quest for you and become an attacker with Glamdring, Fair and Perilous, and Dagger of Westernesse from your questing partner.
My only suggestion is that outside of Guardian of Rivendell, this side looks like they need defending help. I might include Protector of Lórien to help turn Erestor into a 5-defense defender when needed.
