Obeka, Splitter of Seconds + Time Sieve + Thopter Spy Network

Obeka, Splitter of Seconds

Time Sieve

Thopter Spy Network

How it works

1. At the beginning of your upkeep, Thopter Spy Network's first ability triggers, creating a 1/1 Thopter artifact creature token.
2. Deal combat damage using Obeka.
3. Obeka triggers, causing you to get at least four upkeep steps after this phase.
4. Repeat step 1 during each of the additional upkeep steps.
5. Activate Time Sieve by tapping it and sacrificing five Thopters, causing you to take an extra turn after this one.
6. Repeat each turn.

This clever engine harnesses Obeka, Splitter of Seconds to turn a single combat phase into a flurry of extra upkeeps, supercharging the passive token generation of Thopter Spy Network. As those extra upkeeps stack up, Thopter Spy Network reliably floods your board with flying artifact creatures that not only fuel your attacks with Obeka, Splitter of Seconds, but also provide the exact sacrifice fodder needed for Time Sieve. By cashing in those accumulated tokens to Time Sieve, you secure infinite turns while maintaining a devastating aerial lock on the game.
