Myr Turbine + Time Sieve + Myr Battlesphere + Tomb Trawler

Myr Turbine

Time Sieve

Myr Battlesphere

Tomb Trawler

How it works

1. Activate Myr Turbine by tapping it and five Myr, searching your library for Myr Battlesphere and putting it onto the battlefield.
2. When Myr Battlesphere enters, it triggers, creating four 1/1 Myr artifact creature tokens.
3. Activate Time Sieve by tapping it, sacrificing Myr Battlesphere and the four Myr tokens, causing you to take an extra turn after this one.
4. Activate Tomb Trawler by paying 2, putting Myr Battlesphere from your graveyard onto the bottom of your library.
5. Repeat each turn.

This clever loop relies on Myr Turbine and Myr Battlesphere to endlessly flood the board with automata, turning raw numbers into infinite extra turns. When you tap five Myr to activate Myr Turbine's search, you fetch Myr Battlesphere, whose arrival immediately generates four 1/1 Myr artifact creature tokens. You then sacrifice both the Battlesphere and those four tokens to Time Sieve, taking an extra turn right away. To keep the engine running, Tomb Trawler quietly recycles the fallen Myr Battlesphere from your graveyard back to the bottom of your library, ensuring Myr Turbine can find it all over again on your next turn.
