I think this deck shouldn't run basics. 4 colors is reason enough for that. Sometimes you'll lose to Blood Moon, but I guess that's a worthy risk.

My list, for reference:

Lands [20]
4 Polluted Delta
3 Flooded Strand
2 Marsh Flats
3 Underground Sea
3 Tundra
1 Tropical Island
3 Wasteland
1 Creepin Tar Pit

Creatures [14]
4 Deathrite Shaman
4 Stoneforge Mystic
3 True-Name Nemesis
2 Snapcaster Mage
1 Vendilion Clique

Spells [26]
4 Force of Will
4 Swords to Plowshares
4 Brainstorm
4 Ponder
2 Cabal Therapy
2 Bitterblossom
1 Spell Pierce
1 Painful Truths
1 Abrupt Decay
1 Jace, the Mind Sculptor
1 Batterskull
1 Umezawa's Jitte

Sideboard [15]
2 Pithing Needle
2 Meddling Mage
2 Flusterstorm
2 Surgical Extraction
2 Abrupt Decay
1 Path to Exile
1 Engineered Explosives
1 Engineered Plague
1 Zealous Persecution
1 Garruk Relentless/Garruk, the Veil-Cursed

List has been running fine. Playing 4 Ponders allow me to fix my mana ASAP and dig for threats when necessary. Painful Truths is awesome in long games, and plays well with Snapcaster Mage. I play Cabal Therapy instead of Thoughtseize because I don't own any seizes and I'm pretty good at blind hits against certain decks.
