Blizzard has invited eight of the most dedicated Hearthstone players to compete live in a small tournament at BlizzCon this year called the Innkeeper's Invitational. Each player will bring three decks -- they must all be different classes -- and compete against each other in a series of matches. If your deck loses, it's out for good, and that player has to select a different deck. Once all three decks have been eliminated, that player is out of the competition and resigned to watching from the sidelines.
If you're interested in seeing how hardcore card game players go about their games, this is a great opportunity to do so! And it might give us all some ideas for how to modify our own Hearthstone decks in the future. If you won't be attending BlizzCon you can tune in using a Virtual Ticket or check out the matches on the World of Warcraft Twitch channel.
