Deckbuilder's Challenge XXVI (Poll): No pain no gain

{Comments} Yet another Pauper deck from me baby. You put out a ton of zombies, then whop the opponent with Shepherd of Rot and Gempalm Polluter. Those fodder zombs also chomp away at your opponent's health through cards like Maggot Carrier and Tattered Mummy.

{Comments} At first glance, this deck appears to be a mono-Black deck based on Legacy "Demon Stompy" lists to some extent, which are about using Ancient Tomb and various other mana acceleration to power out cards like Archdemon of Paliano and Mardu Strike Leader to quickly run over the opponent.

However, with enough mana and life, we can instead kill our opponent out of nowhere by rushing out Spike, Tournament Grinder, who then wishes for Time Vault and Voltaic Key to give you infinite turns. This also gives us the benefit of letting us put Demon Stompy's hate pieces like Chalice of the Void and Trinisphere in the sideboard instead of the mainboard, since Spike can fetch them as well.

Alternatively, we can try to get a bunch of free spells ready so that we can Storm off into Empty the Warrens or Mind's Desire for an unexpected win, or grab Ancestral Recall or Demonic Consultation to either help us find more free spells or just draw a lot of cards if we are digging for an answer.

{Comments} This contest gives me the perfect excuse to use two of my favorite cards in one deck: Pyrohemia and Fungusaur!
With the help of Cacophodon, Pyrohemia can be used to make Fungusaur bigger and bigger, as well as its siblings Snapping Sailback and War Elemental!
Hopefully I can survive this reckless use of dinosaurs as fuel long enough to trample over my opponent with Primal Rage! I also included Bloodfire Dwarf and Rain of Embers as pseudo-Pyrohemias, and to make the deck fit the challenge requirements.
Ravenous Daggertooth helps offset the damage from Pyrohemia, and Silverclad Ferocidons helps with the late game - although I considered replacing the Ferocidons with Deep-Slumber Titan to keep the mana curve down, and for extra jank points.
Advice is appreciated!
