This loop relies on a clever loop of sacrifice and resurrection, where Ashnod's Altar provides the colorless mana to recast Doomed Necromancer while generating the vital artifacts we need. As creatures hit the graveyard, Pitiless Plunderer steps in to turn every single death into a Treasure token, which conveniently bridges the color gap to pay for our black mana requirements. Meanwhile, Eternal Witness anchors the entire operation by constantly cycling back into your hand when it enters the battlefield, pulling Doomed Necromancer right back out of the graveyard to keep the engine running. While Urabrask the Hidden's tax on opponents keeps the board slowed down, its static haste grant ensures your returning pieces are immediately ready to act, fueling an infinite stream of deaths and sacrifice triggers.
