Time Sieve + Academy Manufactor + Teleportation Circle + Gilded Goose + Elesh Norn, Mother of Machines

Time Sieve

Academy Manufactor

Teleportation Circle

Gilded Goose

Elesh Norn, Mother of Machines

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 elegant loop relies on Teleportation Circle to continuously blink Gilded Goose during your end step, a process doubled by Elesh Norn, Mother of Machines to yield two Food tokens upon entry. Thanks to Academy Manufactor, those generated Foods are drastically upgraded into a total of six artifacts—two each of Clues, Foods, and Treasures—providing more than enough fodder to feed Time Sieve's sacrifice cost. By cashing in five of these newly minted tokens to take an extra turn, you secure infinite turns while leaving your opponents permanently locked out of the game.
