So far I have used a Secrecy build with Strider and Glorfindel with the following:
It's a pretty nifty blend of Spirit and Lore. Together with my son's Outlands deck (all leadership with Hirluin, Imrahil, and Boromir), we destroyed the first two Nightmare APs (we haven't tackled Escape from Dol Guldor yet, though).
My deck building is usually designed with flexibility and adaptibility in mind (with an obsession for believable theme) rather than going for super-synergy. With this deck, I use Elrond's Counsel, Gandalf, Galadhrim's Greeting and Needful to Know, and of course Strider's ability to keep my threat low. Traps and ranger bows keep the enemies in the staging area and hurting. My main strategy naturally is to break out Light of Valinor and Unexpected Courage ASAP. Since this deck is Lore heavy I concentrate on building Strider's resources first. With two UCs on Strider he can Quest, Ranger Bow, and Defend (preferably with Burning Brand). Since Light of Valinor is basically an extra UC on Glorfindel, I save the 3rd UC for Haldir or Gildor, giving them Burning Brand if it comes up to make an extra defender (with sentinel and +1 D if Arwen is around, meanwhile, she's questing). This deck is not super-strong in healing, though, so you have to be careful about that; if you are playing with a lot of Silvan characters, though, you can swap a Daughter of Nimrodel for Silvan Tracker. It does have the ability to cancel hero-wrecking treacheries with 3 Tests of Will, which I save for those really nasty treacheries.
With Stargazer and Forgemaster I get a fun back-and-forth, since Stargazer allows me me set up my next turn's draw, then Forgemaster allows me to reshuffle the deck if there isn't anything I really like. Risk some light really allows for nice planning, and Henamarth Riversong allows me to threat-manage even more with Needful to Know if it would give me a good threat reduction. I often go over 20 threat, then wait for the right combo of cards before disappearing into the shadows with Strider's ability to break out a bunch of secrecy cards all at once. It's fun.
