I know it's a little late. But I still love this deck.
This is in particular was played by Michael Jacob at Worlds 2009. Some lists have [card]Kederekt Leviathan[/card], [card]Corpse Connoisseur[/card] or even [card]Consume Spirit[/card]. This is just one of the many variations of the deck with tweaks either made to suit the player or the metagame.
I've always been fond of graveyard based decks, despite the constant hate cards and other things being printed against it. This deck is basically aiming to abuse [card]Crypt of Agadeem[/card] and the new milling powerhouse found in [card]Hedron Crab[/card] + fetchlands.
You mill yourself using [card]Hedron Crab[/card] and [card]Tome Scour[/card], and cycling [card]Architects of Will[/card] and [card]Monstrous Carabid[/card] to provide more fuel for [card]Crypt of Agadeem[/card]. Once your graveyard is filled with enough copies of [card]Extractor Demon[/card], [card]Sedraxis Specter[/card] and [card]Viscera Dragger[/card], you Unearth the whole lot and swing for your opponent's entire life count.
The deck is obviously weak to graveyard hate and a lot of faster decks, but it goes off surprisingly consistently with Grim Discovery to pull back any [card]Crypt of Agadeem[/card] you happen to lose to your (sometimes) overzealous self-milling.
An important note is to not be afraid of hard-casting [card]Sedraxis Specter[/card]. That card is still worth its three mana cost if you can afford it.
