Hello MMO Champion!
I created a wiki for Hearthstone, if you want to check it out, take a look here: wikihearthstone.com
There isn't much content yet, since the game was announced only a bit more than 24hours ago!
But if you know something that I don't know, feel free to come by and add it to the wiki - all registered users have the right to create and edit articles.
Also, if you have any suggestions what could be done better, please let me know!
