Fain, the Broker + Thornbite Staff + Biotransference

Fain, the Broker

Thornbite Staff

Biotransference

How it works

1. Activate Fain's third ability by tapping it and sacrificing an creature, which is an artifact due to Biotransference.
2. When the creature dies, Fain triggers, untapping itself.
3. Resolve the Fain ability from step 1, creating a 2/1 Inkling creature token that is an artifact due to Biotransference.
4. Repeat.

This elegant loop relies on Biotransference to turn all your creatures and creature spells into artifacts, fundamentally altering how Fain, the Broker interacts with your battlefield. Fain can tap to sacrifice an artifact creature—making use of Biotransference's continuous type-changing ability—to produce a 2/1 white and black Inkling creature token, which immediately enters as an artifact as well. While Thornbite Staff is listed in the setup, the core loop actually bypasses it entirely, since Fain's own sacrifice trigger combined with Biotransference's typing allows you to sacrifice the Inkling you just created to fuel Fain's first ability, looping the sacrifice and creation process indefinitely for boundless enters-the-battlefield and death triggers.
