Time Sieve + Academy Manufactor + Tireless Tracker + Rakdos Carnarium + Elspeth, Storm Slayer

Time Sieve

Academy Manufactor

Tireless Tracker

Rakdos Carnarium

Elspeth, Storm Slayer

How it works

1. Play Rakdos Carnarium.
2. When Rakdos Carnarium enters, it and Tireless Tracker trigger
3. Resolve the Rakdos Carnarium 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 ingenious loop harnesses a land-bounce engine to achieve infinite turns, powered by a brilliant compounding of token multipliers. Every time you replay Rakdos Carnarium, its self-bounce pairs with Tireless Tracker to trigger a wave of creation that Academy Manufactor and Elspeth, Storm Slayer exponentially magnify into a mountain of six artifact tokens—plenty of fuel to repeatedly feed Time Sieve and lock your opponents out of the game entirely.
