I have playing a new take on this at Magic-League since yesterday. Today I played around 30-35 matches, during all day long and with the last list unchanged, and I need to say, I'm really impressed with it. It's a straight UW list, I dropped Ajani and the old Jaces in order to fit the new Jace the Hype-Worthy, and man, he's RIDICULOUSLY BAH-ROKEN paired with shufflers and counter backup. It isn't without a reason the pros and "pros" are going nuts with this card in their articles. When you get an untap with him on the table, you simply don't lose anymore! Dude, this card's ridiculous, put it in a list of your own and try it by themselves. My current UW list looks like:

// Lands
1 [TSP] Academy Ruins
1 [ZEN] Arid Mesa
1 [WWK] Celestial Colonnade
4 [ON] Flooded Strand
3 [ZEN] Island (3)
3 [ZEN] Plains (1)
2 [ZEN] Scalding Tarn
2 [FUT] Tolaria West
1 [R] Tropical Island
3 [B] Tundra
1 [B] Volcanic Island
2 [TE] Wasteland

// Spells
4 [TSP] Ancestral Vision
4 [MM] Brainstorm
2 [FD] Crucible of Worlds
2 [ALA] Elspeth, Knight-Errant
2 [FD] Engineered Explosives
4 [AL] Force of Will
1 [TE] Humility
2 [WWK] Jace, the Mind Sculptor
4 [DIS] Spell Snare
4 [CST] Swords to Plowshares
1 [10E] Wrath of God
2 [ZEN] Spell Pierce
2 [M10] Harm's Way
2 [M10] Ponder

// Sideboard
SB: 2 [ZEN] Spell Pierce
SB: 3 [WWK] Dispel
SB: 4 [WWK] Kor Firewalker
SB: 2 [ZEN] Ravenous Trap
SB: 2 [ALA] Relic of Progenitus
SB: 2 [DK] Tormod's Crypt


And how are you going with WWK available? I'm fully convinced that set is the breath of fresh air this deck was asking for a long time!
