After many attempts.... and maybe just a touch of save scumming...
Nightmare peasant victory.
God damn that was hard.
"Indifference" carried me to victory (Very good vs dreadknights. Very good with "Control undead", very good at forming "straight flushes").
The combos needed to weave through this cardmaze were delightful.
Thank you thank you thank you.
God DAMN that was difficult.
Final battle involved defeating Two 6s and a 5 using a single sellsword and a 2 of blades.
Exited the game with Zero health and zero mana remaining.
