Welcome back!
In a card, you want a
Horn of Boromir deck.
Boromir, Defender of Minas Tirith stays in top shape while your allies do all the fighting. There are two basic takes on this. The first is to use
Galadriel, Lady of Light to play a bunch of Elves for free and then Boromir calls them in to fight. They may add to the archery total and often don't even have to die.
Celeborn, Lord of Lorien is 9 strength and gets healed for free every turn thanks to Galadriel. Elrond gets up to 11, 14 if you use the horn on him twice.
Elrond, Lord of Rivendell is a fine choice, but
Herald to Gil-galad will heal himself twice every turn or heal Boromir for a double. The Elven approach also opens up a whole host of Elven support tools:
Secret Sentinels,
Foul Creation,
Curse Their Foul Feet,
Hosts of the Last Alliance,
The Last Alliance of Elves and Men. Don't try to fit all of these in the deck, of course, but you've got directions you can take it depending on what you face.
I actually can't quickly find a list for a "
Horn of Boromir deck" that fits this bill. The reason is simple, a deck that does all this is only a few cards away from being a type of Last Alliance deck anyway and that deck doesn't fall apart when Boromir dies. There are 5 Last Alliance decks here which include
Horn of Boromir to various degrees, you can reorient one of them around Boromir I'm sure:
https://lotrtcgwiki.com/forums/index.php?topic=12180.msg99411#msg99411The other basic take isn't quite as obvious. Instead of calling Elves in to fight, call Hobbits in to die. It can be very effective though,
Green Hill Country plays all your allies for free and because you're obviously including
Hobbit Farmer you can get the effect even when you don't start. Your Hobbit allies have some nice perks, namely you can funnel all your
Hobbit Party Guest exertions into Bilbo to remove twilight via
Consorting with Wizards.
Three Monstrous Trolls is the only way to keep Moria from adding more twilight than they started with, too.
Silinde can be interesting with
Frodo's Bedroom, it's better than
Rivendell Valley because you can't combine that one with Galadriel's discount (since they're both phase actions you have to pick one). Hobbits can be both free and net you a card, which isn't altogether different from Elrond and
Ottar, Man of Laketown but it's kinda cute. This decklist shows the concept fairly well:

Such a Little Thing was basically made to prevent this sort of deck from ruining Moria. You'll probably want backup possessions to sacrifice. Also,
Saruman, Servant of the Eye will assign Boromir anyway, so make sure that he won't just die if this has to happen. Skirmishing with your companions as little as possible will only get you so far in the end. As the Last Alliance decklists show, if you focus a little less on Boromir you still end up with a solid deck with the upside that it won't crumble when any one specific companion dies. Here's a good example I found with that take, notice how it essentially uses companions as "super allies" as well -- they're all expendable:
