The Ancient Stirrings are actually Once Upon a Time just couldn't add those to the deck yet. 

This deck looks to bring back everyone's favorite deck manaless dredge without probe in the format.

The new cards:

Once Upon a Time adds consistency and allows us to get rid of some of the bad dredge cards we would play along with kind of replacing probe allowing us to keep hands potentially unkeepable before.

Force of Vigor gives us answers for free against most of the hate cards that kill us, and replaces force of will now that we have replaced probe with a green card.

Hogaak, Arisen Necropolis offers some extreme beats and an incredibly fast clock as well as a hard to kill creature. 

cards looking to add:

Mishra's Bauble not sure if this would help need to test it more. Could function as a delayed probe but not sure what to take out for it.

The early game plays exactly like manaless dredge of old. Opt to go second and discard to handsize on turn one, fill your graveyard with ichorids, shadows and dredgers and start attacking.

Prized Amalgam and Ichorid represent your quick out of the gate threats. Hogaak can also come out incredibly fast. 

Using Phantasmagorian you can discard 3 cards and if you have more you would like to, you can hold priority to discard 3 more before it comes back to your hand.

Cards like Cabal Therapy can tear apart your opponents hand while getting valuable dredgers back in the yard.

If the quick aggro doesn't seal the deal you can reanimate the spy to mill your whole deck and then reanimate Flayer of the Hatebound followed by Golgari Grave-Troll to dome your opponent for the win. 

Griselbrand can also be used as a beat stick and a way to dredge most of your deck.

No late game plan.
