Just give me the basic... what do I need to know right off the bat? I played one game Ice Cold and I see how the strategy and tactics interact.
LCG Vet... What do I need to know
Your question is more than a little vague - are you looking for a faction rundown? Cliff-notes versions of the rules? Questions on Core-set composition or deckbuilding restrictions?
I agree with CommissarFeesh, you didn't give us much to work worth. I too am an lcg vet and I can say that this game doesn't take long to get the hang of if you have previous experience. I'm already starting to see a lot of the depth and subtleties of this game.
