On Pandora vs Friekorps misery is an aura so the suits can't ignore it, the weirdest interaction i can think of is if you use inflict they won't take the 1 damage from failing the duel as it's a pulse, but will still take any misery damage.
Personally I've found in games where you need to be close stacking as many passive duels as possible a lot of fun, take fears given form, Barbaros for his challenge aura, the Autumn knights for their "activate and take a wp duel" ability and Tannen for his cooler aura and your opponent will very quickly find themselves without a hand. Throw in the Mysterious emissary and start copying those abilities for extra hilarity.
