I'd definitely use Gandalf (probably
Leader of Men or
Wise Guide) and
SftF.
The Palantir of Orthanc, Recovered Seeing Stone is just naturally a great fit with
Far Seeing Eyes, and
SftF enables a lot of goodstuff (like getting
Lord of Rivendell +
Ottar). Having Gandalf also gives you access to
GOTM, which is a very good safety measure in expanded. I'd also suggest to add
Gil-Galad, HKOTN. You build your deck around
Far Seeing Eyes, and it just doesn't really function well without it,
HKOTN makes sure that you'll have it on board in the fellowship.
Gandalf's Hat is also an interesting card for
Far Seeing Eyes decks as it enables safe double moves.
Something Slimy is another card that I'd run 4 of in any condition based deck with Smeagol, it's just so good.
Another thing I'd like to note is that keeping your deck thin is not always a good thing in expanded, there are so many strategies that you want to counter and so many search cards that enable you to run 1 ofs of specific silver bullets, that if you don't play choke or combo, you are usually better off with a bigger deck, for example my league deck is a 150 cards monstrum, and it has over 90% win rate in league games (about the same in casual).
