The main information is the comparison of the hero class to the MTG colors as well as description of what the hero class can do.
Channel Fireball article: Hearthstone for Magic Players
A well-written in-depth writeup that also compares the rules by Paulo Vitor Damo da Rosa, a top MTG pro player. It provides comparison between the Hearthstone decks and MTG decks which is really cool. (a small interesting reference to League of Legends too!) It also uses some sample decklist as example and great for netdecking. The article was written before the Naxxramas expansion but it is definitely a must read for MTG and non-MTG players.
