This deck comes about after seeing the Beorn card again after a while. To my surprise (despite my small card pool), it works quite well and I find it fun to play.
The quest (unless it's Siege or Battle ) is run by Eowyn and Glorfindel (7 from the beginning) along with Arwen Undómiel, Ethir Swordsman and perhaps Lórien Guide. Eventually the Knights of the Swan can make a statement if all 6 outlands allies are in play. Lórien Guide and Northern Tracker provide some location control.
The deck includes 3 cards, playable thanks to Eowyn's ability and the use of Stand and Fight: Daughter of the Nimrodel, Gléowine and Miner of the Iron Hills . Those 3 cards provide the ability to remove conditions attachments, some card draw and a bit of healing. At the same time, it includes 3 copies of Elrond's Counsel and 2 of The Galadhrim's Greeting to reduce the threat and try to avoid the engagement of many enemies at the same time (especially the stronger ones).
Beorn can withstand the first attacks of the enemies and then use some allies to defend (often with the help of Feint), buying time to be able to have Landroval (excellent reset button for Beorn) or to be able to play Fortune or Fate in case of that the beloved bear succumbed to his injuries. Defender of Rammas and White Tower Watchman are quite efficient at this task, especially the last one with a little help from Arwen Undómiel (3 and 3 ). However, many times another ally can be sacrificed if the situation requires it.
When attacking, Beorn and Glorfindel make a good pair (especially if you can play Dagger of Westernesse and Rivendell Blade) that can take care of the toughest enemies. However, there are some allies that can fulfill the role of attackers such as Elfhelm, Knights of the Swan (better if all 3 are in play), Landroval, Miner of the Iron Hills (if by chance it is in play) or the Northern Tracker.
Gandalf can fulfill the role of fourth hero (for a long time thanks to the cards there are to reduce the threat) or help draw cards (along with Gléowine and Ancient Mathom), reduce the threat or deal damage to an annoying enemy (Gandalf).
