Time Sieve

Tamiyo's Journal

Academy Manufactor

Mirror Image

How it works

1. At the beginning of your upkeep, Tamiyo's Journal triggers, creating three Food, three Clue, and three Treasure tokens.
2. Activate Time Sieve by tapping it and sacrificing five artifacts, causing you to take an extra turn after this one.
3. Repeat each turn.

This elegant loop achieves infinite turns by turning a single upkeep trigger into an engine of self-replication and time manipulation. It all begins when Academy Manufactor transforms the single Clue token generated by Tamiyo's Journal into a massive haul of three Clues, three Foods, and three Treasures every single turn. You then feed five of these newly minted artifacts to Time Sieve, easily paying its steep activation cost to take an extra turn right after this one. Meanwhile, Mirror Image anchors the setup by copying Academy Manufactor, ensuring your token generation is doubled to completely fuel the engine.
