This loop turns a simple sacrifice engine into a self-sustaining engine of life and momentum, anchored by Warren Soultrader converting your creatures into Treasures. Every time Nether Traitor hits the graveyard, Sek'Kuar, Deathkeeper rewards you with a hasty Graveborn token to keep the sacrifice chain moving, while Daxos, Blessed by the Sun tracks every single entry and exit to pad your life total and completely offset the life payments. Meanwhile, Nether Traitor's own shadow and recursion ability lets it slip right back out of the graveyard using the very mana generated along the way, ensuring the cycle can repeat indefinitely.
