Warren Soultrader + Enduring Renewal + Susurian Voidborn

Warren Soultrader

Enduring Renewal

Susurian Voidborn

How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing the nontoken creature that can be cast using one colored mana.
2. When the creature dies, Susurian Voidborn and Enduring Renewal trigger.
3. Resolve the Susurian Voidborn trigger, causing you to gain 1 life and target opponent to lose 1 life.
4. Resolve the Enduring Renewal trigger, returning the creature from your graveyard to your hand.
5. Resolve the Warren Soultrader ability, creating a Treasure token.
6. Activate the Treasure by tapping and sacrificing it, adding one mana of any color.
7. Cast the creature by paying its mana cost.
8. Repeat.

This looping engine transforms the life-recycling safety net of Enduring Renewal into a lethal closed circuit with the help of Warren Soultrader. By using Warren Soultrader's sacrifice ability to feed a cheap creature directly into the graveyard, you trigger Enduring Renewal's replacement effect to instantly bounce that creature right back to your hand while simultaneously generating a Treasure token. Cracking that Treasure for mana pays the cost to recast the creature, allowing you to repeat the cycle indefinitely. Meanwhile, Susurian Voidborn watches every single sacrifice happen from the battlefield, turning your endless loop of deaths into a relentless drain of your opponent's life total until they have nothing left.
