It seems a very powerful deck!
Just in case... if you face a deck that, say, runs desert lords with seasoned leaders and
mumak chiefitain with
mumak and adding threats and don´t let you remove them... This seems to make some noise on your hobbits, cause they will lose strenght bonus from
Everyone Knows, don´t let you put the threats to do things like cancel fierce skirmishes...
Well, this don´t totally screw up your deck but you may consider add Bilbo (the ally) to have some condition discard power, just in the case you really need to...
But the Freeps looks very solid!
For the Nazgul, well... i will let for someone who actually knows something about them to get you the tips...
