I'm not the greatest at deck-building, and only have a single Core Set and the Mirkwood Cycle to work from. (I'm still on the fence about Khazad-dum and the related cycle, since I don't like the theme, but I did get The Hobbit and plan to get both halves of the expansion/cycle).

I usually play solo with two decks, because the balance of "two" players tends to outweigh any weaknesses in my deck-building. (Although I've only tried Passage Through Mirkwood and Passage Down the Anduin, both of which I beat reliably; Escape From Dol Guldur is… something else. I plan to devote some weekends to trying out the Mirkwood quests.)

Looking for feedback on different heroes to try, and of course refining the builds. One deck handles enemies, and the other handles questing and locations. And if cards from Khazad-dum would help sufficiently, I'm all a-go for that justification.

I'm thinking of replacing the Songs, since they were meant to help against Dol Guldur and, yeah, didn't quite work out, even when they were in triplicate. I think I'm going to leave that quest alone….

Thanks for reading!

By the by, I'm recording my progress on the quests here:

spontaneousderivation.com/tag/lord-of-the-rings-the-card-game/

I always play 2-player, and with the same sphere division (spirit/leadership and tactics/lore). Here are some things I have learned:

1) Tactics/lore has trouble with resource generation. The Horn of Gondor is a must-include, but you can't depend on it being drawn. Bifur is also a useful hero here, as he can "borrow" resources from the other player once they get the Steward of Gondor.

2) Our decks are also set up to specialize in enemies or questing. But the random nature of the encounter deck will throw a big monkey wrench in that plan, and you might find that you have 4-6 enemies on the table in the first couple of turns. Some more combat ability in your spirit/leadership deck will be helpful (Longbeard Orc-slayer, Son of Arnor, Silverlode Archer…). And some questing or location power in the tactics/lore deck can help balance things for quests like Emyn Muil (cards like Ancestral Knowledge, which is a Khazad-Dum card, and I see you already are using Blade of Gondolin). Anyway, my point is that you can get in trouble if you are too "pure" in deck specialization.

3) Card draw is king Gleowine, Ancient Mathom, Bilbo (outfit him with Fast Hitch and Dunedain Warning and you have something magic).

4) You may have healing overkill in your lore deck. Self-preservation, Lore of Imladris, and Daughter of the Nimrodel -- great if you are going on a Journey to Rhosgobel, but otherwise you might find you are holding cards in your hand that you don't need, which means those cards are unnecessarily occupying draw slots.

Also, if you are having trouble getting Songs out of your deck, the Rivendell Minstrel can help the lore/tactics deck a lot! That is all I have to share right now… hope I said something that makes sense!

Thanks for the suggestions! You've given me plenty of food for thought.
