Time Sieve + Academy Manufactor + Selesnya Sanctuary + Tireless Tracker + Elspeth, Storm Slayer

Time Sieve

Academy Manufactor

Selesnya Sanctuary

Tireless Tracker

Elspeth, Storm Slayer

How it works

1. Play Selesnya Sanctuary.
2. When Selesnya Sanctuary enters, it and Tireless Tracker trigger
3. Resolve the Selesnya Sanctuary trigger, returning it from the battlefield to your hand.
4. Resolve the Tireless Tracker trigger, creating two Treasure, two Clue and two Food artifact tokens due to Academy Manufactor and Elspeth, Storm Slayer.
5. Activate Time Sieve by tapping it and sacrificing five of the artifact tokens, causing you to take an extra turn after this one.
6. Repeat each turn.

This clever loop lets you bend the laws of time itself by weaponizing a simple land drop. Every time you bounce and replay Selesnya Sanctuary, Tireless Tracker triggers to investigate, which Academy Manufactor twists into a massive windfall of Clues, Foods, and Treasures, all further doubled by Elspeth, Storm Slayer's replacement effect. Once you have accumulated enough trinkets from this cascade of tokens, you simply tap Time Sieve and sacrifice five of them to claim an extra turn, letting you repeat the process until your victory is absolute.
