Kings of the Sea brings back House Greyjoy into the LCG environment. From this perspective, the expansion consists of a Greyjoy deck that is similar to the out-of-the-box decks that you’ll find in the AGoT Core set. With a mixture of both new cards and old school Greyjoy reprints (some modified and updated for the LCG environment), House Greyjoy can once again stand proudly alongside (or, if you prefer, against) Houses Stark, Lannister, Baratheon, and Targaryen in the LCG environment.
