Time Sieve + Tamiyo's Journal + Academy Manufactor + Clone

Time Sieve

Tamiyo's Journal

Academy Manufactor

Clone

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 intricate engine uses Academy Manufactor as its core catalyst, turning the single Clue from Tamiyo's Journal's upkeep trigger into a massive surplus of three Clues, three Foods, and three Treasures instead. With your token economy fully amplified, you easily fuel Time Sieve's sacrifice requirement every single turn to chain infinite extra turns. Meanwhile, Clone enters the battlefield mirroring a key creature to protect or support your setup, ensuring this self-sustaining loop completely locks down the game.
