Welcome! Hopefully someone who plays the Towers Block Sealed leagues online can chime in with play experience, since we use the starters in those leagues. I can say you definitely made the right choice in skipping the Theoden starter, though
Here are the balance changes I'd make. These are 1:1 substitutions, but if you can add enough cards to make each deck 30/30 then you can ditch the starter rules that let you shuffle your discard pile into a new draw deck.
Aragorn -
Ranger's Sword makes this deck very capable right out of the gate, especially given Hobbit tricks when the going gets rough. I'd consider swapping one or both copies for the spare
War and Valor instead, or maybe donating some
Best Company to the Legolas deck so you're not looking at 3 solid fighters plus bouncing Hobbits. I'd also take some high vitality minions from the other decks to soak up arrows if you want them to compete with the Legolas deck. Faramir's Orcs have the added benefit of doing something if the FP can't both kill them and
Dunlending Pillager. Would make the Shadow side a little less boring, too.

Isengard ArtisanLegolas - The FP here have interesting skirmish capabilities, with Legolas hungry to win skirmishes but rarely capable of doing it alone. Of course, they prefer to just kill everything in the Archery phase. The bows might be a bit much with
Quick As May Be and Legolas already in the mix, I might drop a copy. Not sure what you might add, though.
Best Company?
Severed His Bonds? The Shadow side is very reactive, hard for me to guess how it would play out. The Uruk-hai from your spare Faramir deck are great additions to any Shadow side, but they might give this deck consistency if it turns out to be a little
too reactive.

Southron Runner-1x
Southron Marcher+3x
Uruk-hai BerserkerThe Witch-King - Ents are fine for a beginner, but get boring to play and play against pretty quickly since they're just big pools of strength and vitality. The Hobbit shenanigans would be fun if they weren't generally unnecessary given the Ents, so I'd make that trade to put some decision-making in the mix.
Golden Hall can be a very negative experience too, haha. However, the Shadow side here is probably the most interactive of the bunch, giving a player meaningful decisions to make with minion vitality, twilight, and card cycling. I'd see how adding the 2 other copies of
Orc Cutthroat goes, his text is just too good to pass up (but maybe too good to include so frequently?).

StablesFaramir -
Kill Them Now is a dead card
Other than that, this deck is pretty interesting. Sam lets the FP control the deck's breakdown once minions stop roaming naturally, and
Gnawing, Biting, Hacking, Burning gives the Shadow side some recursion and reliability. That combined with using
Isengard Builder's ability might be enough to stop a key double. Its site 7 gives it some killing power, but I don't think it's too much.

Faramir, Ithilien Ranger+1x card of your choice from the spare. I'd go for
Ancient Roads or
Ranger of Ithilien, but really they'll all be better than another copy of Faramir if you start with him

Isengard TinkerBut there's a few things that would be helpful to know. How old are your kids? Have you got any other cards available to you? Are you planning on any games with 3 or more players?
