Thraben Doomsayer + Thornbite Staff + Bloodflow Connoisseur

Thraben Doomsayer

Thornbite Staff

Bloodflow Connoisseur

How it works

1. Activate Thraben Doomsayer by tapping it, creating a 1/1 Human creature token.
2. Activate Bloodflow Connoisseur by sacrificing the Human.
3. When the Human dies, Thraben Doomsayer triggers, untapping Thraben Doomsayer.
4. Resolve the Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
5. Repeat.

By tapping Thraben Doomsayer, you produce a steady stream of Human tokens that instantly feed the voracious appetite of Bloodflow Connoisseur, growing it larger with every sacrifice. The missing puzzle piece is Thornbite Staff, which is equipped to the Doomsayer and grants it a vital untap trigger whenever any creature dies. This creates a tight, self-sustaining loop where sacrificing the token untaps the Doomsayer, allowing you to repeat the process endlessly to generate infinite counters, sacrifices, and deaths.
