Fain, the Broker + Thornbite Staff + Pitiless Plunderer + Ashnod's Altar

Fain, the Broker

Thornbite Staff

Pitiless Plunderer

Ashnod's Altar

How it works

1. Activate Fain's third ability by tapping it and sacrificing another artifact, creating a 2/1 Inkling creature token.
2. Activate Ashnod's Altar by sacrificing the Inkling, adding CC.
3. When the Inkling dies, Fain and Pitiless Plunderer trigger.
4. Resolve the Fain trigger, untapping it.
5. Resolve the Pitiless Plunderer trigger, creating a Treasure token.
6. Repeat.

This elegant loop centers on Fain, the Broker, who holds the engine together by leveraging Ashnod's Altar to sacrifice the very artifacts Fain creates. While Ashnod's Altar fuels your colorless mana pool, Pitiless Plunderer quietly watches each sacrifice and death to reward you with a steady stream of Treasure tokens. Meanwhile, Thornbite Staff equips to Fain (though Fain's own activated abilities and the Altar do the heavy lifting here, turning every iteration into a self-sustaining cycle). The result is an endless cascade of sacrifices and triggers that leaves you with infinite mana and perpetual death triggers.
