Peregrin Took + Cauldron Familiar + Spawning Pit + Insidious Roots

Peregrin Took

Cauldron Familiar

Spawning Pit

Insidious Roots

How it works

1. Activate Spawning Pit's first ability by sacrificing Cauldron Familiar.
2. Activate Cauldron Familiar by sacrificing a Food, returning Cauldron Familiar to the battlefield from your graveyard.
3. Cauldron Familiar and Insidious Roots trigger.
4. Resolve the Insidious Roots trigger, creating a token and a Food token.
5. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
6. Repeat

This clever engine turns the humble cat-and-oven loop into a boundless manufacturing plant by letting Peregrin Took multiply every Food token created along the way. When you sacrifice Cauldron Familiar to Spawning Pit, the cat leaves your graveyard to awaken Insidious Roots, which rewards you with both a Plant token and a bonus Food thanks to Peregrin Took's replacement effect. You can then use that very same Food to revive Cauldron Familiar right back to the battlefield, draining your opponents while fueling the Spawning Pit to repeat the cycle indefinitely.
