This is a white weenie variant that splashes blue for more effectiveness. Here is the deck:
 
4 Soul Warden
4 Soltari Priest
4 Soltari Monk
4 Meddling Mage
4 Cloud Sprite
2 Soltari Visionary
2 Waterfront Bouncer
 
4 Tithe
3 Glorious Anthem
3 Wash Out
4 Swords to Plowshares
2 Disenchant
3 Equilibrium
 
2 City of Traitors
4 Tundra
4 Adarkar Wastes
4 Plains
3 Island
 
Sideboard:
4 Hydroblast
2 Disenchant
3 Winter Orb
1 Wrath of God
3 Story Circle
2 Dodecapod
 
    This deck is obviously extended. I have one 4 tourneys so far with it and placed 2nd in two other tourneys with it. It is a white weenie deck that splashes blue for bounce and the meddling mage, which is extremely effective against a numerous amount of deck types. 
    There may seem a low amount of lands, but thats are what the Tithes are for (use Tithe to fetch Tundra, since its says on the card that Tundra counts as a plains).
    This deck is not so hard to make, except for the Tundras and the Adarkar Wastes, which you can replace with Coastal Towers and Flood Plains if you decide to make the deck.
