Orzhov lifegain-drain built around Niv-Mizzet, Ghost Counsel, which turns every lifegain trigger into cards by paying that much life, so incidental life swings become a steady card engine. Small soul-sisters, aristocrat drainers and sacrifice outlets generate constant gain-and-drain triggers. Well of Lost Dreams doubles the card draw, and draw-payoffs turn the extra cards into more drain. Removal-heavy interaction, recursion loops and loss-prevention safety nets keep the engine running while opponents bleed out. How it wins: Repeated drain triggers from creatures dying, entering and spells being cast, amplified by Vito-style lifegain-to-damage conversion and big hits like Gray Merchant, whittle all opponents down at once, with Bolas's Citadel and Construct a Cosmic Cube as alternate finishers. Key roles: - Lifegain triggers: Cheap creatures and enchantments gain life whenever creatures enter or spells are cast, feeding Niv-Mizzet, Ghost Counsel's draw trigger and its own tap ping. (Soul Warden, Elas il-Kor, Sadistic Pilgrim, Guide of Souls) - Aristocrats drain: Sacrifice outlets plus death-trigger payoffs turn every creature death into opponent life loss and personal lifegain, which in turn draws cards. (Zulaport Cutthroat, Vein Ripper, Viscera Seer) - Lifegain amplifiers: Converting gained life into extra damage or extra cards multiplies each trigger into a lethal loop. (Vito, Thorn of the Dusk Rose, Well of Lost Dreams, Sorin of House Markov) - Draw payoffs: The flood of cards from the commander is converted into further drain, tokens or an opponent's turn. (Psychosis Crawler, Gixian Puppeteer, Construct a Cosmic Cube) - Recursion loops: Reanimation and return effects rebuy the sacrificed drainers and enter-the-battlefield gainers, keeping the aristocrat engine fueled. (Karmic Guide, Reveillark, Whisper, Blood Liturgist) - Life as a resource: Because life is constantly paid for cards and spells, the deck leans on effects that make low life totals safe or spend life for power.
