Right now I have been running two different decks solo (1-handed)

Glorfindel/Elladan/Elrohir (attachment heavy)

Thorin/Dain/Ori

Looking for a second Dwarf deck for playing 2-handed to beat Nightmare quests.

I do have some unique allies in the Dwarf deck but these can easily be switched out if needed.

Thanks in advance

If you are willing to reconstruct you decks, check out my 2 thematic complementary dwarf decks.

Work just fine for nightmare Hobbit saga nad Dwarrowdelf (Did not try them anywhere else).
