I was looking for something that allows playing possessions outside the fellowship phase so that you're not bound by the rule of 4, but I couldn't find one. I did hit one good card for this deck:
Well-Equipped. And all in all, I think you could do with some more Dwarves.
Linnar is a fine
for 7 Dwarf, if you're playing
Dwarven Warrior you could play
Thorin III, or
Gloin, Son of Groin draws you more cards, and Dáin Ironfoot is simply awesome allowing you to discard superfluous minions in the regroup phase and prevent too much flooding of the twilight pool from companions. You don't need all those little companions, I think. If you're worried about swarm, then play
Disquiet of Our People or
Sam, Proper Poet (who doubles as swarm protection and a backup Ring-bearer).
I would also suggest more
Proud and Able and
Still Twitching over
Endurance of Dwarves (which is very dangerous), and more
NPNS is always good. You also don't need the useless possessions just for strength boosts - because of the rule of 4, the value of them being possessions I'm not sure is quite enough and I think you could do better.
