Time Sieve + Academy Manufactor + Thassa, Deep-Dwelling + Gilded Goose + Panharmonicon

Time Sieve

Academy Manufactor

Thassa, Deep-Dwelling

Gilded Goose

Panharmonicon

How it works

1. At the beginning of your end step, Thassa 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 loop harnesses the persistent blinking power of Thassa, Deep-Dwelling at your end step to repeatedly reset Gilded Goose, which enters to drop fresh Food tokens. That baseline creation is violently amplified by Academy Manufactor and doubled again by Panharmonicon, turning a single bird's arrival into an avalanche of six artifact tokens—two each of Clues, Foods, and Treasures. With that massive influx of artifacts online, you simply feed five of them to Time Sieve to seize infinite extra turns and completely lock out your opponents.
