Brago Blink Commander Deck Help

Hello,

I decided to make a Brago blink commander deck (over Roon and Aminatou). I am not a very experienced deck builder so some feedback on the deck would be great. I did playtest it and I had some trouble finishing the game, so some win-con suggestions would be welcome. I am making a blink-centric Brago deck rather than a stax decklist. Thanks.
