Peregrin Took + Cauldron Familiar + Insidious Roots + Bloodflow Connoisseur

Peregrin Took

Cauldron Familiar

Insidious Roots

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur by sacrificing Cauldron Familiar, putting a +1/+1 counter on Bloodflow Connoisseur.
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 0/1 green Plant creature token and a Food artifact token, and then putting a +1/+1 counter on each Plant you control.
5. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
6. Repeat

This clever loop turns a simple alley cat into a relentless engine of growth and attrition, perfectly legal in formats like Commander, Legacy, Modern, Oathbreaker, and Vintage. By feeding Cauldron Familiar to Bloodflow Connoisseur, you send the cat back to the graveyard, which immediately trips Insidious Roots to spawn a Plant token. Because Peregrin Took is watching your token creation, it generously tosses an extra Food token into the mix every time that Plant appears, giving you the exact fuel required to bounce Cauldron Familiar right back to the battlefield. Each cycle drains your opponents, bulks up your Bloodflow Connoisseur with endless +1/+1 counters, and leaves you with an overwhelming army of creatures ready to tap for mana via Insidious Roots or draw you cards through Peregrin Took's hunger.
