So this is "1.0" of a tri-sphere, pure Rohan deck (in terms of characters, anyhow). I'm not much of a deckbuilder as I'm still collecting all of the cards and a relative newb, but I'm pretty happy with this one.

Notes

Gaping Hole #1 (GH1) is having no clear defender. I've sought to remedy this by making Theo as powerful as can be: he gets the Dunedain Warnings for extra defense, Unexpected Courage to be ready, and Plate for extra hp. Not ideal but it's working, even without healing. Gaping Hole #2 (GH2) is the obvious disproportion of Spirit cards, putting a heavy burden on Eowyn in terms of resources. Mitigation comes from Songs of Travel, coupled with Steward (which I put on Theo) as well as Theo's questing ability (he's then readied with UC to serve as defender). The rest of Rohirrim provide some decent tricks, like chumping Eomund to get everyone ready for a big attack (even Sneak Attack Eomund works in desperate times) or sacrificing him for Ride to Ruin; you get his effect, plus the bonus tokens from Ride to Ruin.

Horn of Gondor is mostly intended to be used on Hama, but there aren't too many tactics cards around so he's usually okay. There are also plenty of chumps to use as fodder for his ability.

Why I'm submitting this for feedback, besides the fact that I'm a newb, is because I've only tested it once and everything worked out perfectly. My first hand had Unexpected Courage, two Dunedain Warnings, and a Song of Travel, so Theo was set. My partner was kind enough to make him Steward as well, so I was rolling in the dough; so much so that I had a massive army of Rohirrim by the third or fourth turn.

Should things not go so well, this deck would be in trouble. It's also slightly overweight at 52. Thanks in advance for the feedback!

Curently Rohan is quite specialized in that it does best - questing and location removal, Hama is exeption of this rule, and doesn't quite fit in your deck. Rohan decks should be used vs location heavy quests, like Emyn Mull, and have low chances agains combat heavy (like Carrock) or specialized (like (Rhosghobel).

You have a point, but the idea behind making it tri-sphere was to open Rohan up to more than questing. Using Theo and smaller allies as blockers allows Hama and bigger allies, like Elfhelm, to fight effectively. Swarming works too.

the key for me was to change hama out for legolas. i know its not strictly thematic but this made all the difference. with quick strike and hands upon the bow together makes sure that wont need a defender AND u have the advantage of legolas adding to ur progress on top the great questing speed. another card to add is unseen strike if ur not using it as it helps legolas and dunhere equally. bofur is great when u consider the horn as it costs no net energy then. if u must have a defender id look to gandalf (hobbit version) as he quests without exhausting.

the foundation and ur theme is rock solid here. hama is just overshadowed by a better guy, Legolas, who makes ur theme work better. I wanted hama to work just like u did but i couldnt make it happen without Legolas. since i made that change the deck has won about 80% of the time in solo play against core, khazud-dum, and dwarrowdelf scenarios. perhaps this will help a little.
