Whilst trying to win with Jace, Wielder of Mysteries it occured to me that my yard was always full, what can we do with that..... clearly Muldrotha, the Gravetide is the way forwards. 

So the gameplan is simple, mill yourself as fast as possible with cheap graveyard enablers in Stitcher's Supplier and Glowspore Shaman then use the recursion in the form of Memorial to Folly, Golgari Findbroker, Tamiyo, Collector of Tales and Find // Finality to use your graveyard as a toolbox fetching whatever answers you need at the time.

With Ashiok, Dream Render futher milling yourself the Narcomoeba and Creeping Chill proc fairly reliably giving you some free defence and life gain to enable games to go long where the grindy nature of the deck really shines 

When you go hell for leather on the whole mill yourself plan land drops can be an issue esspecially with only 25 lands which is why Glowspore Shaman is such a good fit for the deck allowing you to reliable hit land drops upto 6 for Muldrotha, the Gravetide or to recur your Memorial to Folly

If you untap with the Muldrotha its easy mode, by that point your graveyard should have answers, lands, walkers, everything you need to close out the game from there. that said Muldrotha is fairly easy to remove so if you find she dies to removal to often consider adding Dive Down or Blinding Fog or some other hexproof effect, although as i write this i realise Negate is a thing, probably more versatile too...

The Plaguecrafter and the Kraul Harpooner serve as surprisingly versatile removal pieces with more creature based answers in the sideboard the Kraul Foragers can gain huge bursts of life in burn matchups the Massacre Girl and Ravenous Chupacabra answer various creature strategies the Thrashing Brontodon covers evrything from Bolas's Citadel to Sorcerous Spyglass or Sentinel Totem and Assassin's Trophy hits, well... everything. There might be a convincing argument to just put them in the 60 but fetching them from the yard can only be done with Tamiyo, Collector of Tales that said you could add some Mission Briefing or Salvager of Secrets to increase the odds of fetching it from the yard 

As almost all of our triggers are ETB effects not on cast effects there is an argument to run Revival // Revenge in place of Find // Finality i opted (hehe) to go with the finds as the finallity can make enough of a difference in game one and without a white source we cant cast the revenge side of things even if we wanted to 

The Maybe-Board contains various cards i tried either as more enablers or as more payoff 

The deck should probably have Jace as a 3of maybe the Tamiyo to but hey im not made of money.
