MTG Angel/ Human white deck. What ya think? ?

Only running 2 swamps so you can play Angel of Despair seems like a bad idea, I would suggest running 4 swamps. Mimic Vat would be a good addition here just for Angel of Despair. I would consider using the new angel card from M12, Angelic Destiny. You should run Soneforge Mystic and the Swords (Feast and Famine, Light and Shadow, Fire and Ice, Mind and Body, War and Peace) just to give you more protection for your angels and more power.
