So I definitely had a good time yesterday with the Pox deck.
My list:

4 Duress
4 Innocent Blood
4 Dark Ritual
4 Hymn to Tourach
4 Sinkhole
4 Smallpox
4 Pox
3 Nether Spirit
3 Chimeric Idol
2 Crucible of Worlds
16 Swamp
4 Wasteland
2 Cabal Pit
2 Mishra's Factory

SB:
4 Infest
3 Spinning Darkness
3 Funeral Charm
3 Oppression
2 Cabal Therapy

In the finals I had a very tough time with (read: lost because of) Life from the Loam. While making the deck I didn't consider that card at all. So I would replace the Oppressions in the SB with Tormod's Crypt. The Oppressions are probably overkill against combo, while the Crypts can cause extra trouble for other decks as well. But the maindeck was performing very well.
