I've been trying out a Cirdan/Theodred/Galdor deck recently and it goes through quite a few of the encounters quite well (I haven't tried nightmare yet but I'm not sure it would fare favourably yet.)
It bases itself on the Noldor theme mostly with a few other things thrown in. It does well against quests that don't emphasize battle/siege early on and that's the advice I need. What kind of sideboard could people suggest to help it with HoN or quests that have a lot of enemies early? If I get a turn or two to set up the deck does fine, some of the quests that throw enemies at you with low engagement costs really quickly like battle of the five armies or most of HoN cycle the deck sort of falls flat and I'm not sure what to add to change it up.
