R/W (Standard) Help

So I just put this deck together:

I'm planning on adding 2 Boros Reckoners, but for the moment I think it's ok.  I'm looking to improve this and make a strong angel deck but I'm finding most of the angels have very high costs.  What type of strategy could I employ to get more land out earlier and make the angels effective?
