I have played through the Kazad-Dum and Dwarrowdelf quests with these decks I skipped the two that have Arwen as an objective ally.
The decks completely demolished every quest.
I also have not tried Shadow and Flame but suspect the decks will get wrecked by it because of the Balrog attacking both decks each turn.
I will report back when I have faced it.
Update-
Just played Shadow and Flame and these decks took it down handily. I didn't realize this when I built the decks but using Galadriel to keep the tactics deck threat at 0 and then playing threat reduction cards for the Elf deck kept the Balrog from attacking until I was ready with all pieces in play.
I used Hama and Feint to protect either deck when the deck raised to 1 threat and could be attacked by the Balrog. Good Decks! Heirs of Numenor quests are up next.
