I'm going to go ahead and start a thread regarding Reid Duke's victory at GP Louisville with this:

4 Deathrite Shaman
4 Noble Hierarch
1 Tarmogoyf
4 True-Name Nemesis
2 Leovold, Emissary of Trest

3 Jace, the Mind Sculptor

4 Brainstorm
2 Ponder

2 Thoughtseize
3 Daze
4 Force of Will

1 Murderous Cut
3 Abrupt Decay

1 Umezawa's Jitte

1 Sylvan Library

1 Forest
1 Island
2 Tropical Island
1 Bayou
3 Underground Sea
4 Misty Rainforest
4 Polluted Delta
2 Verdant Catacombs
3 Wasteland

Sideboard
1 Umezawa's Jitte
1 Thoughtseize
2 Submerge
2 Pithing Needle
2 Flusterstorm
2 Mindbreak Trap
1 Surgical Extraction
2 Dread of Night
1 Painful Truths
1 Nihil Spellbomb

It is obvious from this list that Reid started with Bant and found the white to not be sufficient and cut it completely for more of the traditional Sultai cards. This is made possible with the inclusion of Leovold, who most likely won games singlehandedly. The list is very traditionally built. Nothing out of the ordinary; just a very streamlined list. The big change will be to see how the deck evolves with the inclusion of Fatal Push.
