The latest expansion to the popular card-playing game Hearthstone is here. Kobolds and Catacombs, which features 135 new cards and a new mode called "Dungeon run," introduces some new mechanics like Spellstones to the game. 

That's a welcome addition for the community, who have been complaining for awhile now that the game has gotten too reliant on luck and a few popular decks.
