7. Dragons!
Present in GoT since the finale of season 1, these three cute little fellers, Viserion, Rhaegal and Drogon, have done almost little else but eat and fight amongst each other. Almost little else. They did pay for themselves in the House of the Undying in season 2 however, when they roasted the malevolent warlock Pyat Pree alive, saving Daenerys from a life of bondage in a scene that serves to illustrate their awesome destructive potential. I dont think its a spoiler to say that having Dragons at your command is a major game-changer. Even though season 2 started to deviate a little from the books (understandable, as the story in the books becomes more and more complex and spread, making it harder and harder to adapt), in series 3 you can definitely expect to see more of these bad wee beasties, who pretty soon arent going to be so wee anymore.
