Problem with combos like that in constructed is that opponents will have removal, and you get 2-for-1'ed if that happens. I'm not a believer unless you're playing a Bogle-esque strategy with hexproof creatures.
@callmemaggit, what record did you reach? I'm surprised you didn't mana screw, because it looks so shaky. 7 black sources isn't enough for a main color - I tend to require at least eight sources, and that's cutting it close. Amaranthine Wall seems scarcely playable also. Song is great though. I just played a game against Saproling Migration turn 2 into Song turn 3, and it was genuinely scary. I barely pulled out a win: with opponent threatening lethal, I managed to play Arvad. That was still barely enough - I needed opponent to have nothing since if he attacked with everything I'd survive with only one life. But he did have nothing and topdecked a land ... and I won.
7-2 with this deck!

MountainsI actually got one Ghitu Chronicler around 3rd pick from last. It was amazing since I'd play almost any number of that card if I had half the array of spells I did in this game. Do others really not value it much?
Skittering Surveyor was the LVP since it was literally never drawn except for one game when I was one turn from dying but would've won if I topdecked an untapped land because I'd have the mana to kick Fight with Fire. Thanks, Skittering Surveyor! Otherwise the deck worked quite well. It was fun beating an opponent who had a hand full of auras and tricks but no creatures because I killed all of them. There's a price to trying to cheeze the opponent out. Granted I'm doing that too with my auras, but I did have two Valduk, and cards like Ghitu Chronicler and Sparring Construct can carry auras without much fear of getting 2-for-1'ed. Still, Frenzied Rage was mediocre and never mattered. Dub did, however (first strike is a big deal).
Not sure if Sparring Construct was the right choice here; I had plenty of other playable 2- and 3-drops (various bears, Keldon Overseer). I played Construct because of Teshar, and because it didn't seem like I needed offense, only defense until my powerful suite of removal eventually takes over.
