I think an aggro deck will activate too quickly for this to recover. What can you play in the first 4 turns to help delay the game long enough for this to activate?

your chance to draw land is only 18/60 = 30%. the average deck runs 24 lands 24/60 = 40%. you are very likely to get mana locked. I understand that your running very small creatures one of which is mana ramp, but with 20 creatures and 22 spells, the odds of starting with enough land in your 7 card hand are bad. Also, while I love Kessiq wolf run as a concept, the chance that you will have enough mana to make it be worth while in this deck is poor. Blasphemous Act is cool, and I assume you think you might protect your self with moonmist, but really you won't have the mana to pull off the combo. I would mainboard 4 more land (the rootbound crag from sideboard), and maybe remove the shock or a couple of the spells.
I think I would remove the Elder of Laurels in favor of another Daybreak Ranger. flipped, you can use 1R ability to trigger undying on young wolf which will also trigger morbid for hunger of the HowlPack to pump him further. you can do this during your opponents turn so that young wolf doesn't get summoning sickness from undying during your turn.
