I've never really thought of how an Archfiend deck would run well, but what you have here looks okay. Some things aren't really needed tho, like Falling Down, and Bark of Dark Ruler. Use more general cards, like Sakuretsu, Mystical Space Typhoon, Heavy Storm, and such. Also, take out Archfiend Gilfer for Dark Ruler Ha Des, that way all of your fiends can negate monster effects when they destroy them.
