Hearthstone's 'Goblins vs Gnomes' expansion pack is out today, and it brings some 100+ new cards to Blizzard's addictive digital card game. There's no new adventure like there was earlier this year with Curse of Naxxramas, but this expansion does give us access to a truckload of ridiculous new cards, complete with some insane legendaries. (Download the update and log in before December 19 and you'll get three free GVG packs.)
