We now know Deckbuilding Requirements.
Hmm, so there's a card type we havn't heard about yet. "Role Card." "A role card is placed next to a player's stronghold during setup, and modifies that player's options when building and playing the deck."

You also can't have more than 10 character cards in the conflict deck.
Also "no more than 3 copies of a single card by title can be included in any combination in a player's dynasty and conflict decks." So possibly there might be, say, a personality that could have versions in both?
In the Influence section, it was confirmed that, when spending influence, you can only buy out-of-faction cards from a single clan.
