Ub Teachings

This deck is probably not that good against dredge and would have a hard time with the first game against stax. Im thinking SB would make the stax MU better. Surgical Extraction vs dredge would be just awsome in this deck after SB.
Apart from those decks I think this deck is a 50/50. You should be able to outplay most opponents. And trade creatures as often as possible to then land a Jace and win.

2 Vendilion Clique
4 Spellstutter Sprite
3 Snapcaster Mage
1 Venser, Shaper Savant
2 Jace, the Mind Sculptor

4 Force of Will
2 Spell Pierce
2 Flusterstorm
2 Mental Misstep
1 Mindbreak Trap
1 Dimir Charm
1 Steel Sabotage
1 Cyclonic Rift
1 Visions of Beyond
1 Gush
1 Brainstorm
1 Whispers of the Muse
3 Opt
2 Repeal
3 Mystical Teachings

1 Sol Ring
4 Wasteland
1 Strip Mine
7 Island
1 Misty Rainforest
1 Bloodstained Mire
4 Polluted Delta
2 Underground Sea
1 Swamp

I guess Underground Sea can be cut (save the swamp & fetches) as well as Dimir Charm. Add Back to Basics.
One Mana Drain (or two) would greatly improve the speed of the deck.
Theres just one Gush because you do not want to get behind in the land-race seeing as teachings has a flashback that costs loads.
