The Lords of Winter expansion contains 165 cards (3 copies each of 55 cards), including Eddard and Catelyn Stark, Winterfell, and "The King of the North", Robb Stark. Players of other houses will also find a wealth of new strategies, tactics, and deck-building options.

Finally, as an introduction to the art of customizing a deck, Lords of Winter offers deck lists for two exciting theme decks, one featuring the Tullys of Riverrun, and the other featuring the Direwolves of the North.

This is not a stand-alone game; an A Game of Thrones: The Card Game Core Set is required to play.
