  ===House cards===
  Each House card represents one of the main factions involved in the War of the Five Kings. Each House provides different strengths and weaknesses, allowing for various playstyles to interact within the same game. The House card selected will often restrict cards allowed in the remainder of the deck, by limiting cards that are marked as being allowed solely for another House.
  Characters, Locations, and Attachments often have a House affiliation, and often are used in decks running a matching House card. Some cards have no House affiliation, and such neutral cards may be used freely in any deck. Cards with House affiliations other than the chosen House card may be used, providing the card itself has no restriction, but require an extra expenditure of resources to bring them into play.
