Time Sieve

Academy Manufactor

Thassa, Deep-Dwelling

Gilded Goose

Elesh Norn, Mother of Machines

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 elegant engine transforms a simple bird into a relentless time loop by turning a single blink into a massive surplus of artifacts. At the heart of the machinery is Academy Manufactor, which multiplies Gilded Goose's entry-triggered Food creation into a full trio of Food, Clue, and Treasure tokens—doubled entirely thanks to Elesh Norn, Mother of Machines squeezing extra triggers out of the process. With six fresh artifacts hitting the board every end step, you easily feed the five sacrifices demanded by Time Sieve to seize infinite extra turns. Meanwhile, Thassa, Deep-Dwelling quietly resets the cycle each turn without ever needing to break a sweat as an actual creature.
