This one is pretty simple, we want to get Ashnod's Altar and Fecundity into play and start sacrificing creatures for mana and card draw. The card draw is to find Banefire (the Kannon) and the mana is to cast it for 20+.
Most of our creatures cost so with Ashnod's Altar and one Fecundity out they each net us and a fresh card. Hangarback Walker is explosive once we've ramped up a bit since we get mana and card draw for it and each token it then creates. Using an Elvish Spirit Guide and some of our accumulated mana to case a second Fecundity is usually wise since the double draw means we rarely run out of gas.
If it doesn't face any opposition or disruption the deck can win on turn 4, and I've found (mostly in goldfishing) it does that about 15% of the time. There's probably a technical turn 3 win in here with a perfect 7 and a scry 53, but I'm not calculating those odds. Needless to say, we're going more for style points than consistency with this one!
Edit: Turn 3 win alert! It actually happened. Elvish Spirit Guide to get Fecundity in play on turn 2 (with two land drops). Ashnod's Altar on turn 3, and 3 Hangarback Walkers with a bunch of Kobolds in the top 20 cards, drawing into Simian Spirit Guide and Banefire quickly. I'm learning I might want to be more aggressive with those spirit guides...
