This is a Golgari self-mill and reanimation deck. It fills its own graveyard fast, then brings creatures back from it with reanimation spells, recursive creatures and graveyard-casting permissions. Grist, Voracious Larva turns those returns into a flip: whenever it or another creature enters from the graveyard or is cast from it, paying G transforms Grist into a planeswalker. That planeswalker makes Insect tokens, mills more, and threatens a final ability that copies every creature card in the graveyard as 1/1 Insects. How it wins: The deck overwhelms the table with reanimated fatties and swarms of Insect and Spider tokens, then finishes with mass graveyard-copy payoffs, drain effects from creatures dying or big token counts, or the Doctor Doom library-empty win once self-mill has emptied the library. Key roles: - Self-mill engine: Steady and burst milling stocks the graveyard with creatures and lands, enabling delirium, threshold and graveyard-size counts, and sometimes digging a key card into hand. (Stitcher's Supplier, Skull Prophet, Buried Alive) - Reanimation and graveyard casting: Spells, auras and activated abilities return creatures straight to the battlefield, and permanents that allow casting from the graveyard do the same. Each return also enables the transform trigger on Grist, Voracious Larva and puts big threats into play cheaply. (Reanimate, Victimize, Six) - Recursive sacrifice fodder and value: Creatures that keep coming back feed sacrifice outlets for mana, cards and life drain, turning each death into card advantage and another graveyard re-entry. (Bloodghast, Skullclamp, Cauldron of Essence) - Insect and Spider swarm: Token makers fill the board with Insects and Spiders, and lords and delirium effects grant them +1/+1 and deathtouch, turning chump tokens into a lethal army. (The Swarmweaver, Aatchik, Emerald Radian, Crawling Infestation) - Lands from the graveyard: Milled lands come back to play or hand, ramping the deck and producing Insect tokens or scaling threats along the way. (Hedge Shredder, Icetill Explorer, Formless Genesis) - Graveyard-scaling finishers: Payoffs grow with the number of creature cards in the graveyard, or can win by decking out the deck's own library, closing the game once the yard is full. (Grist, the Hunger Tide, Doctor Doom, Unrivaled, Golgari Grave-Troll)
