Here comes my deck: The Black Cyclone
 
22 Swamp
3 Soul Burn
2 Cackling Witch
4 Dark Ritual
2 Corrupt
3 Bog Witch
3 Culling the Weak
3 Priest of Gix
4 Skittering Skirge
3 Order of the Ebon Hand
4 Hymn to Tourach
4 Drain Life
3 Dark Banishing
 
This deck uses the classic black cards such as the Hymn, the Drain and the Ritual. You get a lot of black mana from Culling of the Weak, Bog Witch and Dark Ritual, so you can burn your opponent with Drain Life and Soul Burn. It can go like this:
 
Turn 1:
Swamp, Dark Ritual, Priest of Gix, Culling the Weak, Drain Life.
