Eloise, Nephalia Sleuth + Jinnie Fay, Jetmir's Second + Bloodflow Connoisseur

Eloise, Nephalia Sleuth

Jinnie Fay, Jetmir's Second

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur by sacrificing another creature.
2. When the creature dies, Eloise's first ability triggers, and Eloise's second ability triggers if the creature was a token.
3. Resolve the first Eloise trigger, creating either a 2/2 Cat or a 3/1 Dog creature token due to Jinnie Fay.
4. Resolve the second Eloise trigger, if applicable, causing you to surveil 1.
5. Resolve the Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
6. Repeat.

This looping mechanism turns the relentless hunger of Bloodflow Connoisseur into a self-sustaining engine by utilizing Eloise, Nephalia Sleuth to churn out Clues whenever a creature perishes. Because Jinnie Fay, Jetmir's Second gracefully steps in to replace those artifact tokens with agile Cat or Dog creatures, you suddenly have a fresh supply of fodder to keep the sacrifice chain moving indefinitely. Every iteration not only grows Bloodflow Connoisseur larger with a new +1/+1 counter, but Eloise's built-in surveil trigger also lets you sift through your library with absolute precision.
