Deck assistance

[davinator400]

So I'm a fairly new player and bought the 2011 core set in hopes of putting together a deck and perhaps checking out a few FNM events, my first attempt at deck building was a white/Blue deck, mainly because the cards seemed the best I got in the 8 boosters. However, I don't think it will stand up against any sort of tuned deck. I was wondering if maybe someone could give me a little help, I'll post the deck I've put together so far and perhaps you could share your ideas and tell me where I've made mistakes and potential cards that would fit well, any advice is greatly appreciated.
