Hi.
I have the core, whole first cycle, the two delux and the first 4 packs in the last cycle. I haven't really opened everything yet. What I want to be able to is playing casual and being able to make a good deck for each faction. Should I just stick to the core plus every delux? Or can I sprinkle with war packs as I see fit without disturbing the "balance"? Like if you want a fair balanced card pool do you either go just core and delux (like you can sort of do in netrunner) or do you need to go all in (which I feel you almost have to do in Lord of the rings)?
