All set and chapter packs in the LCG model are legal.
Due to a large number of new players, the unavailability of some chapter packs we will be allowing players to use up to six proxy cards. These proxies must be of a high quality (should be color print outs of the card to actual size). No hand written proxies will be accepted.
Ooooh, interesting. Now, does that mean six cards in total, or six different cards, plus any duplicates?
