Last night I lost my first round with this deck. It was a matchup against delver burn, and my record is now somewhere around 20-1 VS delver.
Game 1: I got land screwed. Stuck at 2 lands, drawing nothing but Soltari Foot Soldier and a little-too-late Squadron Hawk, Delver flipped early and hit too hard to recover. Lightning Bolt finished me off the turn I drew my 3rd land.
Game 2: Kept an opener with Rune of Protection: Red, Rune of Protection: Blue, 3 lands and 2 others. I got both runes down and my opponent couldn't win. Cleanup was easy
Game 3: Kept an opener with lands and spells, including Rune of Protection: Blue. Sadly, it was the wrong rune. My opponent threw 21 points of burn at my face before I could stabilize. He was happy to have finally beaten me!
I finally lost a round, but I'm still very happy with my record so far. Infect still hasn't triumphed in 1v1, and Eldrazi got curbstomped by Unmake and Pacifism.
