Apologies in advance if this is the wrong subforum to post in, but it seems the most trafficked so I figured I'd ask here.
As a newer player (strictly LCG era) who really only has the Core set so far, I've been trying to find a bit of concrete info on formats and not having much luck. From what I can gather AGOT transtitioned from CCG to LCG before CoC, and so there might have been a few rough spots and unclear things along the way.
There is an LCG cards only format, correct? Is it the prevailing format or is using pre-LCG cards still very popular? Lastly, where does the LCG legality begin - with Core Set and "A Clash Of Arms"? I'd hate to accidentally purchase something not usable in a LCG format.
Thanks in advance for any answers you guys can provide.
