Time Sieve + Academy Manufactor + Teleportation Circle + Gilded Goose + Yarok, the Desecrated

Time Sieve

Academy Manufactor

Teleportation Circle

Gilded Goose

Yarok, the Desecrated

How it works

1. At the beginning of your end step, Teleportation Circle triggers, blinking Gilded Goose.
2. When Gilded Goose enters the battlefield, it triggers twice, creating two Food, two Clue and two Treasure artifact tokens due to Academy Manufactor.
3. Activate Time Sieve by tapping it and sacrificing five artifact tokens, causing you to take an extra turn after this one.
4. Repeat.

This intricate setup revolves around the end-step engine provided by Teleportation Circle, which continuously blinks Gilded Goose to farm resources. Each time Gilded Goose enters the battlefield, Yarok, the Desecrated doubles its entry trigger, while Academy Manufactor magnifies the resulting output so you receive a flood of paired Food, Clue, and Treasure tokens instead of just simple sustenance. With five artifact tokens ready to be cashed in during your turn, you simply tap and sacrifice them to Time Sieve, trading them away to take an extra turn after this one and locking down the game in an endless loop.
