This is a cEDH-style Korvold deck that turns sacrifice into cards. Every permanent sacrificed, whether fetchlands, Treasures, Lotus Petal, tokens or creatures, puts a +1/+1 counter on Korvold and draws a card, and his enter and attack triggers force a sacrifice each time. Free sac outlets and fast mana feed that engine while dense tutors and reanimation assemble compact persist/undying loops, which drain or burn out the table. How it wins: Tutors and reanimation assemble an infinite sacrifice loop, such as a persist creature with a counter-cancelling enabler on a free sac outlet, and Goblin Bombardment, Murderous Redcap, Mayhem Devil or the drain creatures turn the endless deaths into lethal damage. Key roles: - Persist and undying loops: Persist creatures return forever when something stops -1/-1 counters from sticking or cancels them with +1/+1 counters, and undying creatures loop the same way when a -1/-1 counter removes their +1/+1 counter. With a free sac outlet each pass makes unlimited enter, death and sacrifice triggers, each of which also draws Korvold a card. (Murderous Redcap, Putrid Goblin, Metallic Mimic) - Free sacrifice outlets: Repeatable, costless ways to sacrifice creatures keep the loops running and turn spare bodies into mana, Treasure, scry, cards or damage, all of which trigger Korvold. (Viscera Seer, Goblin Bombardment, Ashnod's Altar) - Death payoffs: Creatures that drain, ping or punish on every death or sacrifice convert a loop or a big sacrifice turn into a kill, and some also make Treasures that refuel Korvold. (Blood Artist, Mayhem Devil, Zulaport Cutthroat) - Sacrificable fodder and token doubling: Fetchlands, Treasures, Lotus Petal and recursive creatures give Korvold a steady stream of permanents to eat, and Chatterfang doubles every token into extra Squirrel bodies. (Chatterfang, Squirrel General, Pitiless Plunderer, Squee, the Immortal) - Reanimation package: Combo pieces dumped into the graveyard or lost to removal come straight back to the battlefield, giving a second route to assembling a loop. (Entomb, Reanimate, Victimize) - Tutors and fast mana: A dense tutor suite, rituals and mana rocks find and cast combo pieces quickly, and Food Chain and Culling the Weak turn creatures into extra mana. (Demonic Tutor, Survival of the Fittest, Finale of Devastation)
