Enduring Renewal + Blood Vassal + Jet Medallion

Enduring Renewal

Blood Vassal

Jet Medallion

How it works

1. Activate Blood Vassal by sacrificing it, adding .
2. When Blood Vassal dies, Enduring Renewal triggers, returning Blood Vassal from your graveyard to your hand.
3. Cast Blood Vassal by paying 1.
4. Repeat.

This clever loop relies on Enduring Renewal's replacement and trigger effects to turn a simple sacrifice into a self-sustaining engine. By utilizing Jet Medallion to reduce the casting cost of black spells, you can cast Blood Vassal for just {1}{B}, exactly matching the {B}{B} mana generated when you sacrifice it to its own ability. Every time Blood Vassal hits the graveyard, Enduring Renewal immediately rescues it right back to your hand, allowing you to replay it endlessly.
