I'm just making decks based on the number of cards I have for each culture, it's predominantly Moria, next Sauron, then Isengard, and for Nazgul I think I have 4 minions. I have 4 copies of 2 Nazgul and a copy of WK from Towers I might bring over, but that deck might then be too strong.
I've got a nice Isengard collection from Towers (probably as much as I have Moria and Sauron combined for Fellowship), but I think uruks will already be the strongest shadow side. I built all of my decks 30/30, but I think I should add cards to my Moria swarm decks so
They Are Coming is usable, and maybe those will be threatening too. There's not much for card drawing, unfortunately. I'm guessing a lot of good Fellowship cards were traded for better Towers/King cards (there's at least 3 copies of
Host of Moria). Some Isengard Orcs from Towers will make a full deck possible, and the Sauron trackers provide much-needed card drawing for a swarm.
Adding weapons is a great idea, Boromir and Aragorn will finally be consistent skirmishers rather than just picking off the little guys while someone else loses to a bigger fellow. I don't want to add
Lorien Swordsman (or most any generic companion from later sets) yet because strong redshirts weren't Fellowship's style, but those swords will at least help Legolas and Haldir not look like total wimps. I am adding a
Balglin I found. I have a cache of
Samwise the Brave and a few
Aragorn, Heir of Elendil to give more Fellowships a fighting chance.
The Advance orcs seem too strong to add without buffing every Free Peoples side. Same with
Worry, I can't guarantee these fellowships will even win a majority of their battles without a good hand of pumps. I removed all pumps from the Uruk deck because their strength levels are already above the fellowships and the damage is crushing. There aren't any battlegrounds in Fellowship Block, so I'm steering clear of the battleground cards anyway. Maybe the balancing act isn't worth while and I should just play Towers Standard. The goal of Fellowship Block was simplicity, and I don't think I'm accomplishing that
