Tamiyo's Journal

Academy Manufactor

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.
