Practically this deck rewards you for discarding both you and your opponent's hand.
Especially the creature Nyxathid, which becomes a cheap 7/7 for 3 mana.
Then after the discard-fest, play Liliana Vess and use her 3rd ability to swarm and finish your opponent off with all your discarded cards from the grave.
The only problems here are mana. If you don't get enough mana and a decent set of creatures at the start, it's pretty much game over. But thankfully, there's Dark Ritual to help.
And if you really love one-hit wins. Easily fill your opponent's graveyard with more than 10 cards, and use Guiltfeeder for the win.
