Freeps could use more copies of
Aragorn, HttWc, or maybe somethig (
Sam, Son of Hamfast) to remove burdens and help biding high to pull Aragorn at site 1. Burn Sam ASAP so you dont give him the 6° companion.
An Able Guide needs quite a set up to work, shadow player has to leave Twilight unused, maybe
Gondor's Vengeance, or
Pursuit Just Behind could help you double moving. At this point youll be needing
Might Of Numenor to remove the exertions.(if you choke well his expencive minions will be in hand, or unluckly in discard

)
Moria seems like a problem since you have no condition removal,
PATHS might do the job, wich also fits the
Greenleaf -
Aragorns bow -
A Ranger's Versatility strategy.
Armor is a must to deal with Uruks, maybe not too many since youll be choking, but as stated before can help against the balrog (only if you get a gondorian with his weapon).

Filibert Bolger, Wily Rascal is great against Nazgul and the Balrog, but keep in mind how often you want to use
Sting.
The Council of Elrond seems way to expencive for a choke theme deck, nice deck size reduction, but 2 its a lot of pool. So far never played
Hosts of the Last Alliance, seems nice, but expencive again.
I would suggest:
+1Sam,
Son of Hamfast+1
Armor+2
PATHS (3 bid+1Prancing Pony+2
PATHS-3 Sam =3 Burdens seems right)
+2
Might Of NumenorIf you dont get to start with a bid of 3 kill them in
Ford of Bruinen!

Hopefully...

-2
The Council of Elrond -2
An Able guide-1
A Ranger's Versatility (if you started, rivers come from site 6 on, unless facing Nazgul)
-1
Hosts of the Last Alliance.
Shadow side could exchange
Goblin Runner for
Morgul Gates, also better use for
Morgul Skulker 
If you are planing to add burdens, Balrog takes away your site 5, so i would consider adding
Must do without Hope here youll be needing to cycle before(to get) and after(get rid of)
MDWH, so
Gwemegil looks nice.
+2
Gwemegil (First one Cycles the other)
-1
Asfaloth+1
Morgul GatesThis leaves 33-33 deck but with Cycling

Add a
Enquea, LOM, and if you draw him early discard and recycle with
Morgul Skulker.
+1
Enquea, LOM+2
Morgul Gates+4
Must do without Hope-4
Goblin Runner-1
Ulaire Nertea, Messenger of Dol Guldur-1
Wraith World-1
Ulaire Otsea, Lieutenant of MorgulWell, I think i went too far on the review

but, anyway hope its usefull.
First, nice to see some new, interested member(s) in here!
As this is Choke, I would prefer to run
Sam, FC with 2x
Bill the Pony instead of
Sam, SoH and maybe
A Talent for Not Being Seen.
As for that, I bid high but I don't use
PATHS,
Hobbit Stealth isdoing a good job, too. I do not like
Armor, thus, it does not fit in the strategy.
The coucil of Elrond is another part, adding 2 twilight seems not so hard as I remove it with
HttWC, and grabbing Last Alliance is very importantto have a strong Fellowship, and I am thinking of adding Elrond-Drawer and
Secret Sentinels.
An able Guide is also a key of the strategy, cus' when you put in just a few twilight, the opponent isn't playing anything at all and you double-move, you'll get swarmed during the following move. Same for
Sting.
Agree
Might of Numenor.
"-1
A Ranger's Versatility (if you started, rivers come from site 6 on, unless facing Nazgul)" I AM playing Nazgul

As for Shadow, Goblinn runner is there cus' you can also do a little Swarm with
Goblin Runner,
Morgul Skulker, Swarm Nertea etc.
Balrog is ust a random surprise for Site 5, and that's why I do not want to add other cards for him.
I decided to not run
Shotgun Enquea, and as for the Nazzies are all unique, I it's better to run 3x Twilight Enquea. Another reason is
Wraith World which is a pretty strong Combo with
RBU, adding much more burdens then
MdwH.
And as for Otsea, I'm planning to make my Witch-King fierce to kill the Ring-Bearer then, just look at other topics like in Towers where I'm running something similar to this, but with
Fell Beast.
