Fain, the Broker + Intruder Alarm + Pitiless Plunderer + Bloodflow Connoisseur

Fain, the Broker

Intruder Alarm

Pitiless Plunderer

Bloodflow Connoisseur

How it works

1. Activate Fain's third ability by tapping it and sacrificing another artifact, creating a 2/1 Inkling creature token.
2. When the Inkling enters the battlefield, Intruder Alarm triggers, untapping all creatures.
3. Activate Bloodflow Connoisseur by sacrificing the Inkling.
4. When the Inkling dies, Pitiless Plunderer triggers, creating a Treasure token.
5. Resolve the Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
6. Repeat.

This clever loop transforms Fain, the Broker and Bloodflow Connoisseur into a relentless sacrifice engine, supercharged by Intruder Alarm's static ability which untaps your creatures every time a new token arrives. Pitiless Plunderer acts as the crucial economic backbone of the operation, turning every departed Inkling into a fresh Treasure token to keep the mana flowing. As Fain, the Broker repeatedly recycles artifacts into new flying fodder, the entire engine loops smoothly to generate boundless death triggers, creature sacrifices, and glowing +1/+1 counters.
