Twin Councils of the Wise
This fellowship came from an idea Sappidus on the Cardboard of the Rings Discord suggested as a way to make building Council of the Wise decks less onerous with physical cards. Build 2 Council of the Wise decks using the same list of cards except for heroes. This allows the player to pull out 2 copies of each card from their collection instead of just one.
I would call these "good stuff" decks. Strong hero line ups with cards selected to provide a wide array of answers to the encounter deck.
Heroes and attachments
Eowyn and Arwen are the questers in each deck. These were pretty comparable to each other with strong willpower stat and discard abilities to make use of Elven-light. Lanwyn is a bit of hybrid questing and combat hero since she might ready if there is surge. This possiblity also helps keep the deck with Arwen willpower about as strong as the one with Eowyn.
Both have a strong sentinel defender and ranged attacker to be able to support each other in combat. These aren't as close to each other Eowyn and Arwen. The sentinel and ranged are key though since there are a number of attachments that can be played across the board. You can prioritized playing the attachments on the more useful defender or attacker for the scenario. Beregond being better for high attack enemies while Grimbeorn's built in action advantage better for scenarios with weak swarming enemies.
Special attention was paid to the traits and attachment restrictions. Bow of Yew can work well on Legolas, Grimbeorn, and Lanwyn. Legolas likely will get the most mileage out of Rohan Warhorse. Grimbeorn could get some readies especially if his ability kills an enemy while defending. Same could be said for War Axe.
A few strong defending allies with Defender of Rammas, Derndingle Warrior, and Gondorian Spearman in case readying attachments do not come up. Honour Guard can help mitigate not getting any defense boosts or pseudo-healing.
Rider of the Mark is a really nice toolbox card in these decks providing decent willpower and repeatable shadow mitigation.
Events and the Contract
The events are intended to be useful for more scenarios, but you won't be playing events just to trigger the contract. The contract acts more of a additional bonus. This can be very helpful even so. In my test game, I often would play an event as needed then get a resource or card that I needed and helped me continue to get ahead. I found this to be very flexible as I could select the best option at the time and better adapt to the game state.
