Time Sieve + Myr Battlesphere + Thassa, Deep-Dwelling + Elesh Norn, Mother of Machines

Time Sieve

Myr Battlesphere

Thassa, Deep-Dwelling

Elesh Norn, Mother of Machines

How it works

1. At the beginning of your end step, Thassa triggers, blinking Myr Battlesphere.
2. When Myr Battlesphere enters the battlefield, its first ability triggers twice, creating eight 1/1 Myr artifact creature tokens.
3. Activate Time Sieve by tapping it and sacrificing five Myrs, causing you to take an extra turn after this one.
4. Repeat each turn.

This clever engine locks down your opponents in infinite turns by leaning on a brilliant synergy of blinking and token generation. It all kicks off during your end step when Thassa, Deep-Dwelling exiles and returns Myr Battlesphere to the battlefield. Thanks to the doubling power of Elesh Norn, Mother of Machines, the Battlesphere's arrival generates a massive army of eight 1/1 Myr artifact creature tokens instead of the usual four. You then feed five of those newly minted artifacts to Time Sieve, sacrificing them along with a tap of the artifact to immediately secure an extra turn.
