Changed it up a bit, because I felt the same way Coshmo did. Added 2 Talrand's Invocation to give myself a better air presence, added 4 Shock for extra damage, and put in 2 Satyr Firedancer for funsies. Took out some counters and the 2 Nivmagus Elementals to make room for the additions. It seems to play a bit better now, but there's always room for improvement!
Edit 2: Made some more changes. Took out the Talrand's Invocation, the Unsummons, and the Blustersqualls. I think Blustersquall is a great spell, but when most of my critters are little weenie creatures, I felt the spell wasn't pulling its weight. I added 1 more Pillar of Flame, and 3 more counterspells (after playing this deck with some friends in multiplayer, I felt like I needed some more counters). Added 1 more Satyr Firedancer and 1 Dragonshift - if for whatever reason the game goes on for that long, having this in the deck ends things quickly. And, if not, having just 1 doesn't hurt much at all.
