GodisaGeek: "When you first start up Hearthstone, you’ll be treated to a full tutorial explaining how to play the game in such a way that even someone that’s never even looked at a Trading Card Game in the past with know exactly what they’re doing within a matter of minutes. You’ll start of with Jaina Proudmoore – the Mage – and once you’ve finished with the tutorial, you’ll be well equipped to jump into either the Practice mode, or the Play mode. The Practice mode does exactly as it says on the tin, allows you to practice the game against a selection of A.I. controlled characters based on the nine classes from the original World of Warcraft game – Mage, Druid, Hunter, Warrior, Warlock, Priest, Paladin, Rogue and Shaman – all of which are able to be unlocked by beating their respective heroes on the Practice mode. Once you’ve unlocked all nine classes, you’ll be able to take your skills to the Arena in order to, hopefully, collect more cards, more gold and more fame."
