Uh... Yeah, wouldn't recommend old school Archfiends. They commit suicide way too fast, so against the newer decks they kind of die. COupled with a lack of field protection... Yeah.

I direct you to [url=http://yugioh.wikia.com/wiki/Dark_World]Dark Worlds[/url] and [url=http://yugioh.wikia.com/wiki/Infernoid]Infernoids[/url]. YOu could also go look up zombie decks- with the Isolde/Tristan engine coming they're able to pull out big monsters pretty quickly, like Zombiestein. They've also got Zombie master to pull from grave and zombie world to screw with tributing, so you can easily put some pressure on.
