The idea of the deck is to play a spirit lore deck with access to the best weapons and armors of the the other two spheres. Both Beregond and Haldir of Lórien are amazing with access to the items and Bard son of Brand gives them access without needing a tri-colored deck. The deck is designed for multiplayer games. It has a lot of cards in it, that can help other players too.
The heros have an effictive willpower of 4, but you have several allies with a 1:1 ratio of costs and willpower. Arwen Undómiel, Ethir Swordsman, Galadriel's Handmaiden and the Silvan Refugee are good allies for the first round. So the deck quest power relies very much on its allies.
Beregond. With a Gondorian Shield, a Hauberk of Mail and the help of Arwen Undómiel he can come up to a basic defense of 8.
Haldir of Lórien is your killer. Bard son of Brand can add two additional attack, when you have enough allies to quest. Tough enemies should be taken by other players, blocked by Beregond and killed by Haldir of Lórien and their attackers to let you focus on questing.
Beregond, Double Back, Galadriel's Handmaiden and Well Warned can help you to manage the threat and keep it <30 for a while. An important aspect of the deck is that all of these cards can reduce the threat of other players too.
Power of Orthanc is the default tool against conditions. The Free Peoples (with 7 traits out of your heros) becomes far more powerful with 3 or 4 players. Also your access to any item and the ability to return it to the owner's hand with Bard son of Brand can be very useful for other decks, that need access to card out of there spheres.
