Updated the post; you can NOW create articles on decks that are 'classics' (it should be variants on widely popular decks, such as CCYB, RoL-Hope, Shrieker Rush, Ghostmare, Mono-Life, etc.), and provide sufficient proof that it works against a particular set of opponents (AI3, Half-Bloods, FG, Arena, PvP, etc.).
EDIT: Whoooooooooooooooooooooooooooooooooooops. >_<
