Modern American Midrange

I was wondering if you guys had any thoughts on my new UWR Midrange deck for the Modern format.  Been testing it and so far it's done great! (My only problem has been playing against BW tokens so far,) but what could I do to maybe make it better?

Also if there's a better way to upload a deck let me know cause this is my first post.
