So I've tried ELO a bit, but haven't done very well. I use a mono-Nightmare deck and have all of the cards in the clan except the 4 Collectors and Kolos. I would appreciate a solid deck construction that'll give me a shot in ELO. Thanks!
From someone who HATES playing against nightmare... I don't want to exacerbate the issue, but I've found it's easier to deal with Nightmare decks that try to fit a 5* in vs ones with solid cores. A lot of people like Karrion, but he becomes a dice roll whether they think you're bluffing or all-out pilling with him. It's Pan, Edwin, Phyllis, Sargh, glorg that win the matches from what I've seen.
But seriously.. don't play nightmare.. people will wish for bad things to happen to you
