This clever loop transforms a simple sacrifice outlet into an engine of endless rebirth and profit, fueled entirely by the interplay between Warren Soultrader and Nether Traitor. By repeatedly feeding Nether Traitor to Warren Soultrader, you trigger Sek'Kuar, Deathkeeper to leave behind a hasty Graveborn token, which instantly buffers your life total thanks to Social Climber's alliance ability. That very same token can then be sacrificed to pay for Nether Traitor's resurrection cost, keeping the cycle spinning indefinitely while generating infinite Treasure tokens and life.
