Just to clarify, I'm not saying that I *know* TaEowyn can't be replaced with another hero in any non-solo-mono-tactics deck to make it a better deck. I'm no master deckbuilder, and I could very well be wrong on that point. I'm saying I don't see *how* Eowyn is replaced with another hero to make it obviously better. I'd rather see a detailed example showing how I was wrong and learn something rather than "win" and learn nothing.
I'm also now madly curious about which combination of heroes would have the highest winning percentage against all nightmare quests, for each sphere combination. I was thinking about starting with Seastan's public decks and sorting by likes, but I'm not sure all those decks are meant to be broken.
