Faerie dragon is going to become a very, very popular card in the competitive Hearthstone constructed deck scene. The fact that this card is unable to be targeted by spells guarantees that it will deal it's 3 damage to a minion if dropped in the early stages of the game before players have the mana to access their area of effect cards. There are a couple of exceptions, most notably Arcane Missiles, but in most cases he's going to eventually bump into a minion for 3 damage.
