Time Sieve + Myr Battlesphere + Teleportation Circle + Loyal Apprentice

Time Sieve

Myr Battlesphere

Teleportation Circle

Loyal Apprentice

How it works

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

This ingenious setup locks down the game by feeding an endless stream of artifact tokens straight into Time Sieve, guaranteeing you infinite turns to dominate the board. The engine is reliably fueled each cycle by Teleportation Circle, which blinks Myr Battlesphere every end step to constantly replenish your sacrifice fodder with four fresh Myr tokens. Meanwhile, Loyal Apprentice provides the crucial fifth artifact creature right at the beginning of combat whenever you control your commander, perfectly rounding out the five artifacts required by Time Sieve's activation cost.
