Time Sieve + Cybermen Squadron

Time Sieve

Cybermen Squadron

How it works

1. Declare a sufficient number of nonlegendary artifact creatures as attackers.
2. Each creature's myriad ability triggers, creating a token copy of each creature attacking each other opponent.
3. Activate Time Sieve by tapping it and sacrificing five of the creature tokens, causing you to take an extra turn after this one.
4. At end of combat, exile any remaining tokens created by myriad abilities.
5. Repeat each turn.

By utilizing Cybermen Squadron to grant myriad to your nonlegendary artifact creatures, a single swing at multiple opponents floods the board with a massive army of token copies. These token copies serve as the perfect disposable fuel for Time Sieve, whose activation effortlessly sacrifices five of those newly minted artifacts to immediately chain an extra turn. Because myriad triggers every single combat, you can reliably feed the Sieve turn after turn, locking your opponents out of the game entirely under an endless succession of attacks.
