I picked up two Core Sets from GenCon. The idea is to build eight permanent decks (one for each faction) so that my friends and I can pick up and play quickly whenever the mood strikes us. We're content to play unsplashed-faction decks built using the cards from the Core Set. This means we're not customizing our pre-constructed decks and won't likely be buying upcoming Chapter Packs. But since the decks constructed from two Core Sets leave our decks 13 to 14 cards shy of the 60-card minimum required by the rules, I'll be picking up either another Core Set or the first Chapter Pack made available (depending on the card count and distrubution).
A third Core Set would give each of the eight decks a second (and probably much-needed) copy of the suggested neutrals given in the back of the rulebook. That's going to leave room for seven more cards for the Stark and Greyjoy decks and five more for the other six. So my question to you guys is this: how should I go about fleshing out these decks? I've ruled out adding 3rd copies of any unique characters, attachments, or locations, and I'm thinking three more characters and two more events would probably be the best route to take. I haven't settled on the specific cards yet, so I'm open to whatever suggestions you guys have for rounding out each deck.
