3. Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
4. Cauldron Familiar and Quintorius trigger.
5. Resolve the Quintorius trigger, creating a creature token.
6. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
7. Activate Umbral Collar Zealot by sacrificing Cauldron Familiar.
8. When Cauldron Familiar dies, Ygra triggers, putting two +1/+1 counters on it.
9. Resolve the Umbral Collar Zealot ability.
10. Repeat.

This intricate engine revolves around Ygra, Eater of All, whose static ability turns every creature on the battlefield into a Food artifact in addition to its other types. This transformation means that Cauldron Familiar can be sacrificed to pay its own return cost—or fed to Umbral Collar Zealot—while simultaneously fueling Ygra's triggered ability to grow massive with +1/+1 counters every time a Food hits the graveyard. As Cauldron Familiar repeatedly enters and leaves the battlefield, Quintorius, Field Historian capitalizes on those cards leaving your graveyard by churning out an endless army of Spirit tokens. Together, these pieces turn a simple cat into an infinite loop of drain, lifegain, surveil, and token creation.
