I built that deck and played a few games with it last night. The creature density made the decisions in the deck a bit more difficult. Protecting your threat is super important because you don't know when you'll get another one. It's a bit like infect in that way, only infect has other ways to find threats. 16 lands seems super greedy. I would be more comfortable with 18 in this build the three drops out of the board seem really hard to play on curve which is when you would want them. Unless you have daze or force back up rushing creatures out is rough. The deck still has the problem with emptying it's hand and not being able to reload fast enough. This deck is capable of stringing together a ton of damage out of no where. Stormchaser is better than expected, brainstorm or daze even if they pay for it protect him from bolt and the evasion is nice. I think I would like to see slip through space or some other cantrip in the deck somewhere maybe in the forked bolt or spell pierce slot. As a two of it should be fine.
