I've had this deck brewing for a few weeks now as I thought through some of the new discard mechanics. A friend of mine used a similar deck for the Murder at the Prancing Pony event, and I was impressed with how well it worked, so I wanted to try building one myself.
It's been pretty successful so far, beating 4 of the 5 Nightmare decks I've tried on the first try without any modifications--and I probably only lost Journey to Rhosgobel because I didn't put in any healing cards.
