Time Sieve

Academy Manufactor

Izzet Boilerworks

Tireless Provisioner

Peregrin Took

How it works

1. Play Izzet Boilerworks.
2. When Izzet Boilerworks enters, it and Tireless Provisioner trigger
3. Resolve the Izzet Boilerworks trigger, returning it from the battlefield to your hand.
4. Resolve the Tireless Provisioner trigger, creating two Treasure, two Clue and two Food artifact tokens due to Academy Manufactor and Peregrin Took.
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 intricate loop transforms a humble land drop into an eternity of extra turns by turning a single trigger into a flood of metal. When Izzet Boilerworks enters the battlefield, its bounce ability pairs with Tireless Provisioner's landfall trigger to continuously replay the land, while Academy Manufactor and Peregrin Took exponentially multiply every single token created into a massive bounty of Clues, Foods, and Treasures. With that overwhelming surplus of artifacts readily available, you simply tap and sacrifice five of them to Time Sieve to take an extra turn, untapping your board to repeat the entire process indefinitely.
