Remove:3x
Hidden Knowledge - it's really not necessary. 4
Noble Leaders with 4 tokens on it is enough. Especially with extra skirmish events
Seeing Stone of Minas Anor and
Seeing Stone of Orthanc - those will be of no use. You'll have enough artifacts to pump Elendil without them.
The Shards of Narsil - same as for seeing stones.
Ring of Barahir - With 4 copies of
Noble Leaders in deck, I'd try to use them the same turn I get them, so there is not much chance to see tokens at the start of turn.
Defend It and Hope - this will be of very little help to your deck as it is not a wounding deck.
Replace:3x
Aragorn, Heir of Elendil with 1x
Aragorn, Captain of Gondor or
Aragorn, King in Exile - you'll have strong companions with lots of pumps and defender +1 won't make much of a difference, while healing every turn might help a lot.
2x
Elendil, The Tall with 1x
Elendil, The Tall - you need just 1 copy, because you'll be pulling him out with
Denethor, LoMT if you don't get him.
2x
Knight's Spear with 4x
Gondorian Sword - potential damage bonus can be very helpful and it can help a lot to cycle your hand. Potential strength bonus from
Knight's Spear will not be much needed with all the pumps you'll have.
2x
Swordarm of the White Tower with 4x
Sentinels of Numenor - with Heir of Elendil gone, you'll have no defender + companions and potential strength bonus in Fierce can help.
Add:1x
Coat of Mail - play on Boromir to protect him from swarm
1x
Armor - play on any other companion you seem fit. It can help a lot against Uruks, Cave Troll of Moria, Balrog,
Troll of Cirith Gorgor and other nasty dmg+ minions.
2x
Might of Numenor - extra healing is always helpful
This will effectively remove 11 cards from your fellowship and add 8 other which makes it a total of 34 cards. This will help your drawing a lot. You'll have no condition removal, but you'll have plenty of healing and pumps to survive even a triple run (when you play Narsil on Elendil). There is a very good chance to get at least one of these cards in your first two hands: Aragorn, Elendil, Narsil and Anduril. Those you don't get, you pull out with Denethor. Your toughest match will probably be after that card pulling at site 4 as you will probably add a lot of twilight and your opponent will have lots of cards in hand, but with a wee bit of luck you can easily survive. If you happen to get
Hard Choice early, you can use it to heal Denethor at site 3 to use him again or keep him healed.
As for your shadow, you should decide whether you want to corrupt your opponent or kill him with
Easterling Captain and
Easterling Army mostly. If you want to go with former add more
Vision From Afar and
Gathering to the Summons. If you got with the latter, add
Raider Bow and
Ships of Great Draught. In any case you go, instead of 4 copies of
Gollum, Stinker, go with 1 copy of Gollum and 4 copies of
Captured by the Ring. Also switch your site 8 to
Northern Ithilien. You don't need 4 copies of
Ulaire Enquea, LoM, 2 will do fine or 3 if you really like it.
