First, you have two copies of 
Sam, Son of Hamfast so you can use 
Isildur's Bane without any worries. Consider adding 
Lady of Light for healing Orophin and Rumil and for playing them and Elrond for free. Add one Gwemegilfor sure, one cycles the other. You might drop oen 
Athelas or 
Gift of Boats instead.
And where is your random Balrog, 
Durin's Bane? Everybody passes site 5 
the bridge of Khazad-dum* so I think adding him wouldn't be that bad. I like it how you make use of Breeding Bit. I guess you combine it with 
Uruk Soldier?
Saruman's Power. You don't have any conditions, so you mgiht add this one. 
Bred for Battle might help you win skirmishes.
I'm not sure if I should give it a 3 or a 4, I'm tending to 4, but I think I'll vote later.
