Just a thought, but maybe this could be shifted to a threat build (
Cantea FTW,
Lemenya ET, even
Held Ground). Threats interfere with
Thorongil (and
Ranger's Longbow) as well as Rumil/Orophin SE.
They Feel the Precious can prevent wounds in a pinch. Cantea brings possession removal to the table, and
Morgul King and/or
Ring of Terror can get some more recursion going.
Or to get more use out of burdens,
Cantea BA can force assignments against 0-resistance companions. Against large fellowships,
Fell Rider ensures your Nazgul make it to the skirmish (unless they trip over
IB), and then BA chooses who dies.
Dark Horseman can be a threat/burden machine against ARBs.
Put Forth His Strength could be splashed into Morcs. NappyKorn had an Expanded deck that was using Enquea/Ring of Rancor to kill companions, and of course initiative/burdens/threats come with the territory. In Standard... just beat up guys the hard way?
