I would probably go mono white with this one, I can't really see a reason to splash red, with so many double/triple w and double r, you're likely to get mana screwed. White has some decent and cheap spot removal you can use, like Pacifism and Oblivion Ring. Seems like you have an Angel tribal thing going on here. You might want to run a few Seraph Sanctuary. Also with so many 1x cards your draws are going to be really inconsistent. I would run 4x of some solid cards with low CMC (1-3 mana). I can't tell what strategy you're going for, but if you put it in description I'll suggest a few good cards for the strat.
