Blizzard is keeping the hype train real as the days march closer to to it's August release of The Grand Tournament Expansion. After a large game patch tomorrow that will knock the game out of commission for a couple hours we will be getting an all new Tavern Brawl highlighting some new cards in the upcoming expansion allowing us to try them out pre-expansion launch.

"Wednesday’s Grand Tournament Match features a thrilling Brawl between two potent forces. One, led by that mysterious master of magic, Medivh, will be packed with minions eager to heed your call to battle and power up with Inspire. Standing against them will be the mistress of the hunt, Alleria, along with a full cadre of master jousters who are poised to grow mighty with each contest won."
