Mounts, Dwarves, and a Bear (Dwarrowdelf Cycle)
This fellowship went through the whole second cycle (Nightmare versions of the first three quests). The Beorn deck can handle most enemy waves. It needs an average of 2 turns to set up, but Beorn can buy you some time. It also has condition attachment removal with Miner of the Iron Hills, who can be recursed with O my To me! O my kinsfolk!. The Rohan deck handles cancellation. It should be noted that the decks have some nice properties against the Foundations of Stone. For example, the second quest stage makes you discard from the top of your deck, which is especially nice for the Dwarf deck. And the third quest stage makes you discard weapon, item and armor attachments, but all the attachments in both decks are none of these types !
