YuGiOh! Any ideas for a Fiend deck?

From the looks of it, Archfiend Empress would show what kind of deck you should built. basically a Dark Fiend deck, maybe a deck centering on Pandemonium field card or maybe the Dark World Deck. I prefer the Dark World deck since it is stronger and more suitable to be use with Archfiend Empress since they themselves are kind of deck that puts themselves in the graveyard and Archfiend Empress could benefit from it. Also in the YGO OCG, a new structure deck is about to be released centering on the Dark World archetype on the 18th of June called Devil's Gate so I guess this is a chance for you to built a deck around it since many new Dark World support will be available.
