Chris Andersen has had some recent success with this deck. He made 13th at an open in January with it:

1 Sensei's Divining Top
2 Sword of the Meek
3 Thopter Foundry

3 Baleful Strix
2 Snapcaster Mage

4 Brainstorm
2 Counterspell
4 Dig Through Time
4 Force of Will
2 Mental Note
2 Spell Snare
4 Swords to Plowshares
4 Thought Scour

1 Supreme Verdict
3 Thoughtseize

1 Seat of the Synod
1 Creeping Tar Pit
4 Flooded Strand
4 Polluted Delta
4 Tundra
3 Underground Sea
1 Academy Ruins
1 Karakas

Sideboard:
1 Nihil Spellbomb
2 Sensei's Divining Top
1 Tsabo's Web
1 Ethersworn Canonist
1 Baneslayer Angel
3 Counterbalance
1 Detention Sphere
1 Humility
1 Seal of Cleansing
2 Enlightened Tutor
1 Surgical Extraction

At the invitational, he made top 8, and I believe he had to go at least 6-2 in Legacy to do that. The list was almost exactly the same with these changes:

Maindeck: -1 Mental Note, +1 Ponder
Sideboard: -3 Counterbalance, -2 Sensei's Divining Top, -1 Surgical Extraction, +3 Hymn to Tourach, +2 Tasigur, the Golden Fang, +1 Engineered Plague

I wanted to play the Invi list last night at my local but I forgot my Thought Scours and only had 3 digs. So I played the full set of Ponders, a Gifts Ungiven, and a Lingering Souls, and cut the Mental Note for a basic island.

I promptly got obliterated by BUG Veteran Planeswalkers, Infect, and Enchantress. (However, I did get to resolve a Gifts for Sword of the Meek, Baleful Strix, Force of Will, and Academy Ruins against Enchantress, which felt good until they comboed off the next turn.)

Has anyone else tested this deck?
