It's August 24th and if you've been counting down the days like I have then you'll know that The Grand Tournament starts today for Blizzard's Hearthstone: Heroes of Warcraft.
The major changes The Grand Tournament are introducing include Inspire buffs and Jousts. Inspire minions get some sort of bonus whenever you use your hero power. This bonus ranges from spawning new minion to buffing current ones in a variety of ways. There are also quite a few companion cars that will make your hero power cost less, do more, or open it up to be used multiple times per round. Jousts are when certain cards will reveal a minion from each player's deck. The player with the higher mana values for their minion wins the joust, and the outcome for the player who initiated it could be a buff to the minion or spell or an extra card or minion.
More info can be found on the official site, and you can take a look at all of the 132 new cards in the photos section of the Hearthstone FaceBook page.
