Time Sieve

Tamiyo's Journal

Academy Manufactor

Mondrak, Glory Dominus

How it works

1. At the beginning of your upkeep, Tamiyo's Journal triggers, creating two Food, two Clue, and two 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.
