The second expansion for Hearthstone, Blizzard's card game by the way of quasi-religion, has just been released. Called The Grand Tournament it brings 132 new cards to the, err, digital table. Which is a lot. 132 new cards means new strategies to learn, decks to build, and other card-related things. Anyway, Hearthstone continues to grow from strength to strength as one of the most fun and rewarding card game thingies.
