My current list after Innistrad comes out:
//Main Deck:

1 Necroplasm
1 Nihilith
3 Tombstalker

4 Liliana
2 Crucible of Worlds
4 Dark Ritual
4 Hymn to Tourach
4 Inquisition of Kozilek
2 Mental Misstep
4 Pox
4 Sinkhole
4 Smallpox

3 Mishra's Factory
12 Swamp
4 Urborg, Tomb of Yawgmoth
4 Wasteland

//Sideboard:
2 Crucible of Worlds
2 Do or Die
4 Duress
4 Leyline of the Void
3 Sun Droplet


Changes:
-2 MM
-2 Swamp
-4 Disfigure
+4 Dark Ritual
+4 Liliana

I consider this to be a new age of pox. Dark Ritual is absolutely necessary with a bomb like liliana, if it hits play the first turn of the game, the opponent has a very hard time recovering. Factories and Nihilith are my two best outs against Jace TMS. That and preventing them from ever getting to 4 mana ;P
