The Dimholt is a wasted site three. When are you ever going to be playing Wraiths and have the room to add three threats at site three (not considering the additional threats to play any Wraith anyways). You'd be much better off playing
Beacon of Minas Tirith for healing or
Hall of the Kings.
I prefer to start two copies of
Dead Man of Dunharrow and run four copies of
Aragorn, Driven By Need.
Frodo, Weary From the Journey is not King-Block legal...maybe
Frodo, Resolute Hobbit?
Isildur, Bearer of Heirlooms is your best bet with Wraiths anyways.
Dagger Strike is nice if you are running Frodo, but I think it is a wasted card. Personally, I think Wraiths are better built for Movie Block because
Banner of Westernesse is such a good card for Wraiths).
I have you at 33 cards right now. If I were playing this deck, I would:
Add:Isildur, Bearer of Heirlooms (Ring-Bearer)
Aragorn, Driven By Need x3
Dead Man of Dunharrow x1 (start two)
Elessar's Edict x1
Hearts Raised x2
Remove:Frodo, whatever copy you end up with
Sting, Bane of the Eight Legs x2
Dagger Strike x2
End of the Game x4
That would put you at 32 cards...seems just about right! On the Shadow side, you could probably live without two Morgul Whelps and run another
Morgul Brute instead. Also,
Morgul Destroyer would be a better idea than
Ulaire Nertea, Black-Mantled Wraith. In fact, four Morgul Destroyers and four Morgul Brutes would probably do you a lot better than the Nazgul in general (Attea seems the only one that would be a great fit).
Hope this helps. If you do decide on Movie Block,
Banner of Westernesse x4 instead of 4 Spectral Swords.
