First, I want to know what I get 5 points to start off with? And what personal humiliation must I endure to get MTS's starting points of 42??
I absolutely MUST win The Cheat. The future of Strongbadia depends on it!
Answer: Erebor Battle Master. Thorin. We Are Not Idle. (more on this answer in a bit)
Second Question: Two decks = two sets of three hero’s. Which Six do I choose? (Bombur?)
Answer: This is completely dependant on how you intend to synergize your decks (jumping the gun to your next question)… You can either do it by sphere (eg, pair up two spheres for each deck and let 'er rip), or try and base it around mechanics within a core group of cards. Honestly, this is the only race in the game that we have this much luxury to make this decision around. A blessing AND a curse… I'll throw some possible combos/ideas after the next question.
Third Queston: Synergies? (Dain, Thorin, Thrain, Bombur?)
Answer: There's lots of them now! For the longest time, I had run a tri-sphere Dain, Bifur, Dwalin deck and being VERY successful with it. Then Rich's use of Thalin with the first two of those inspired me to switch from blue to red. The deck works much better for "large" enemies, as it allows for using the Erebor Battle Master. However, since I still love my blue escape cards and threat reduction, I find that the costlier red cards and needing to drop Narvi's Belt into the deck make it suffer a bit of card-draw/resource sluggishness. I haven't tried the Thorin, Ori, Nori combo yet since I haven't had much playing time in lately. But Nori has pretty much identical stats to Dwalin and has a better built-in threat reduction for dwarven decks (better quester than Dwalin as well).
Personally, I'd scrap the sphere-focused decks. Mostly because of Thorin and Dain. If you're really going to run 6 dwarven heroes, Dain is already a MUST HAVE. Thorin is a bit pricey, but having him on the same table as a "ready" Dain means he quests as hard as Eowyn does. Gonna let that sink in for a second… So I would definitely have them both out. But are you gonna run two 12-cost Leadership dwarves in the same deck (adding a third to them means you start at around 30 threat)? In my mind, I'd split them up. So that means that my sphere-focused decks are out the window. If you AREN'T using Thorin, then it's still completely doable. I'd run Dain, Gloin, and Nori in one deck and Bifur, Thalin, and Gimli in the other. Drop SoG on Dain, use him and Gloin to create massive wealth (what dwarves do best right?) and Nori to get rid of all that nasty threat. Bifur can steal all that wealth from the two horders and help pay for the spendy Tactics and Lore cards to keep Gimli and Thalin alive.
Here's where my mind is just going to wander for a bit about Bombur… I was kinda "Meh…" about him when I first saw him. However, if running two entire decks of dwarves, I think he'll be a beast. Run a strong Dain, Bifur, Thalin deck such as Rich has fleshed out before. This will provide a strong base for operating from. Then combine Bombur with Thorin and Ori to start. That means if you can get one cheap dwarven ally out on round 1, then you generate an extra resource and draw an extra card starting in round two from there on out. If you have a Narvi's Belt (or song) on Thorin, you definitely will want to get EBM out. Bombur alone gives him +2 attack. Then you start dropping "We Are Not Idle" and all you need is him alone and he generates two more resources and a card for you. Have a UC on him to ready him and use his 5 health to soak up the damage from defending!
