After playing a few games with the pre-constructed decks I, as a long time CCG player, couldn't stop myself from putting together a couple of decks. While solo-sphere decks are, eventually, going to be the most efficient way to go, right now it's physically impossible to build a tournament legal solo sphere deck. With all of the great things this game has going for it, this is my biggest complaint: I really wish they would have added another 10 cards per deck so that we could build a legal solo sphere deck with a couple of sets. After the first expansion comes out this should be possible, but we won't have many options...it's going to be a solid few months before we start getting some flexibility.
So, that being said, it looks like we'll just have to make due with dual-sphere decks. Dual sphere decks have the distinct disadvantage of having one sphere under-represented and only producing 1 resource per round, so tricks need to be employed to combat this. This problem interestingly makes Leadership the best sphere to team up with, as they can bring the uber powerful Steward of Gondor to the table, something that is a 3x necessity when playing a dual sphere deck in order to get your under-represented sphere up and running as quickly as possible.
So with 2 sets of the base game I started looking at spheres and what fits best together. While there are some obvious and powerful combos with Leadership and Tactics, I decided to pair Leadership with Knowledge to fill in some of it's weaknesses, namely lack of card draw and healing. This left me looking long and hard at Tactics and Spirit, which actually fit together quite nicely as well. So I built a couple of decks. Both have problems, though Tactics/Spirit has the most, mainly resulting from their complete lack of people. Also Horn of Gondor is a ghetto replacement for Steward of Gondor, but we make due with what we have. Here's what I came up with:
Leadership/Knowledge
1x Aragorn (L)
1x Theodred (L)
1x Berevor (K)
Allies (24)
3x Snowbourn Scout (L)
3x Guard of the Citadel (L)
3x Silverlode Archer (L)
3x Miner of the Iron Hills (K)
3x Daughter of Nimrodel (K)
3x Gandalf (U)
2x Faramir (L)
2x Gleowine (K)
2x Henomarth Riversong (K)
Attachments (10)
3x Protector of Lorien (K)
3x Steward of Gondor (L)
2x Forest Snare (K)
2x Celebrian's Stone (L)
Events (16)
3x Sneak Attack
3x Valient Sacrifice
3x Ever Vigilant
3x Gandalf's Search
2x Common Cause
2x Lorien's Wealth

Leadership is definitely the most 'wealthy' sphere and Knowledge brings an insane amount of card draw to the table, so they go together quite well. The spread of hero's is fantastic: Aragorn and Theodred work well together questing, while Berevor is a solid defender or a card drawing machine. Though there are a few uniques that have multiple copies (notably Steward), Protector of Lorien gives you something to do with the extras. Ideally you are looking to get Steward on Berevor ASAP in order to bump her production up and get the Knowledge side of your deck going. Plenty of solid combo's in the deck to mention here (Leadership is full of them), if you haven't take a look at this thread, it's a pretty decent look at some of the card interactions in this game's early life: http://www.boardgamegeek.com/thread/644768/lord-of-the-rings-combo-compendium. There are also some crappier cards in the deck just by necessity, I would probably dump most of the action cards when better ones come along (aside from Ever Vigilant and Sneak attack.)
Tactics/Spirit
1x Eowyn
1x Legolas
1x Gimli
Allies (18)
3x Gondorian Spearman (T)
3x Veteran Axehand (T)
3x Horseback Archer (T)
3x Lorien Guide(S)
3x Northern Tracker (S)
3x Wandering Took (S)
Attachments (12)
3x Dwarven Axe (T)
3x Blade of Gondolin (T)
3x Horn of Gondor (T)
3x Favor of a Lady (S)
Events (20)
3x A Test of Will (S)
3x Quick Strike (T)
3x Blade Mastery (T)
3x Feint (T)
2x Hasty Stroke (S)
2x Unexpected Courage (S)
2x Rain of Arrows (T)
2x Stand Together (T)

First, the problems with the deck. The biggest problem is that both spheres are severely lacking in allies, especially inexpensive ones. There's no way I'd be using Northern Tracker (really really good but horribly expensive) or Wandering Took if I didn't have to, and I'd like even more allies in the deck. The fact that Tactics has 0 allies with any willpower is crap, hopefully that changes soon. It's going to be really tough to get the Spirit side of this deck going, but once you get a Lorien Guide or Northern Tracker you are really helping cover Tactics huge weak spot. Tactics also needs a solid defender ally that can actually block a couple of hits without dying, because Legolas and Gimli are attackers, period.
So, why even pair them together? Because even if you don't play a single Spirit card, Eowyn singlehandedly improves Tactics questing ability by leaps and bounds. Between her questing (and dumping your excess cards to boost her Willpower) and Legolas you should be able to quickly build up tokens without too much Ally support. Each hero has an item in the deck: Gimli has the Axe, Legolas has the Blade and Eowyn has the Horn (and Favor, to a lesser extent.) The Horn is mostly crappy, but if you can scrape up a few extra resource tokens out of it for Eowyn it's worth it. Hopefully something better comes along soon.
So that's what I've got so far, looking forward to what other people put together.
