This is a Great Army of the North which paradoxically uses underdeeps movement to get factions at non-underdeeps sites. I haven’t played it in a while, but as I recall it worked quite well.
Start:
Buthrakaur
Umagaur
Crook-Legged Orc

Roadblock will do nicely, if you don’t mind being a cheezemeister.
Key Sideboard Cards:
Terror Heralds Doom
Orcs of Angmar
Long Grievous Siege (for Cameth Brin)
3 Hill-Troll
Play Tips:
The Hog goes to Mordor to Descend Through Fire (6 MPs, lotsa DI/Prowess). Meanwhile B&U use gangways to get to various surface sites where they can play factions. The deck could probably use some tweaking, so let me know what you think.
