Forum:Good Dark Cards?

I've got an idea for a new deck, but I plan on pulling it out as a surprise to a bunch of folks who use this wiki a lot, so I'm keeping details scarce. Basically, I need dark monsters, prefferably low level, with either milling effects, high defense, or good ways to get other cards in the game. NO EFFECTS THAT RELY ON YOUR GRAVEYARD. Outside of monsters, I need some spells and traps that mill both players' decks, as well. Any advice is appreciated. Thanks!
