I think you're running too many draw power cards considering the fact it's mono-colours. I'd run 3 Inspiration , remove the 4 Think Twice and replace with 3-4 Fog Bank (one of the best mono-blue blockers in standard right now) plus 1-2 Runewing if you're still want more draw power.
Also I wouldn't run that many Essence Scatter , try replacing a few with Encrust or card:Judge's Familiar if you're allowed to use the latter, as they're more flexible plus help lock down the board better.
Finally you NEED to run Talrand, Sky Summoner and card:Talrand's Invocation, getting three 2/2 flying creatures out for 4 mana is deliciously powerful.
Hope this helps!

Thanks! I had Fog Bank originally (it's one of my favorite cards), but took them out for Essence Scatter on the logic that they both essentially take opposing creature out of the fight, but Essence Scatter can't be burned, helps Delver, and leaves mana up for Ludevic's and so forth.
Talrand would be awesome, if I can find some. I'm torn between Inspiration and Think Twice for that card draw slot. I guess I'll try it both ways.

card:Judge's Familiar I would think is really important here

card:Judge's Familiar will run in my big-boy azorius deck, but he's blue-white, so no Monday night bonus packs for winning with a mono deck.
