I would drop {Augur of Bolas} to 1-2. You're draw power makes 4rather unnecessary. And this is furthered by {Restoration Angel} flicker effect. I only run one augur in my bant control and have had no issues. This being said, look at throwing in 1-2 {Terminus} for miracle draw. 2-3 {Geist of Saint Traft} for midrange and swing potential. Lastly, for recycling and maintaining deck advantage, 1 {Elixir of Immortality}.
