Time Sieve + Myr Battlesphere + Teleportation Circle + Peregrin Took

Time Sieve

Myr Battlesphere

Teleportation Circle

Peregrin Took

How it works

1. At the beginning of your end step, Teleportation Circle triggers, blinking Myr Battlesphere.
2. When Myr Battlesphere enters the battlefield, its first ability triggers, creating four 1/1 Myr artifact creature tokens and a Food artifact token due to Peregrin Took.
3. Activate Time Sieve by tapping it and sacrificing the Food and Myrs, causing you to take an extra turn after this one.
4. Repeat each turn.

This clever engine turns your end step into a reliable workshop for infinite extra turns. It all starts with Teleportation Circle quietly blinking Myr Battlesphere every single turn, which floods your board with fresh bodies. Thanks to Peregrin Took's replacement effect, that influx of Myr tokens also generates a steady supply of Food tokens to pad your resources. Once you have enough artifacts accumulated, you simply tap Time Sieve and sacrifice the newly minted Myrs and Food to take another turn, locking down the game before your opponents can catch their breath.
