Ygra, Eater of All + Cauldron Familiar + Ravenous Intruder + Quintorius, History Chaser

Ygra, Eater of All

Cauldron Familiar

Ravenous Intruder

Quintorius, History Chaser

How it works

1. Activate Cauldron Familiar by sacrificing a Food.
2. Ygra triggers, putting two +1/+1 counters on it.
3. Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
4. Cauldron Familiar and Quintorius, History Chaser trigger.
5. Resolve the Quintorius, History Chaser 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 Ravenous Intruder by sacrificing Cauldron Familiar.
8. When Cauldron Familiar dies, Ygra triggers, putting two +1/+1 counters on it.
9. Resolve the Ravenous Intruder ability.
10. Repeat.

This loop turns a modest cat into an engine of relentless growth by leveraging Ygra, Eater of All, which transforms every creature on the battlefield into a Food artifact. With Ygra on the board, Cauldron Familiar can easily sacrifice itself—or any other creature—to return from the graveyard, while Ravenous Intruder provides the necessary outlet to instantly send the Familiar right back to the graveyard. Meanwhile, Quintorius, History Chaser watches cards leave your graveyard to flood the board with Spirit tokens, generating infinite life drain, life gain, and infinitely large stats for your creatures in Commander, Legacy, Oathbreaker, and Vintage formats.
