Produces: Infinite turns, Lock


- Color identity
- UB
Prerequisites
You have at least two opponents. You control a number of nonlegendary artifact creatures that do not have summoning sickness equal to five divided by the number of opponents you have minus one, rounded up. Opponents cannot block and kill creatures you control.
Steps
- Declare a sufficient number of nonlegendary artifact creatures as attackers.
- Each creature's myriad ability triggers, creating a token copy of each creature attacking each other opponent.
- Activate Time Sieve by tapping it and sacrificing five of the creature tokens, causing you to take an extra turn after this one.
- At end of combat, exile any remaining tokens created by myriad abilities.
- Repeat each turn.
How to execute this combo
The "Time Sieve + Cybermen Squadron" combo takes 5 steps in order. Make sure you have the mana open and permanents listed in the prerequisites before you start — opponents can respond between steps.
The end result: Infinite turns, Lock.
Practice the line offline: lay out the cards, walk through each step, and note where you can lose the combo (summoning sickness, lack of priority, removal on a key permanent). In game, announce each step clearly; in casual play you can offer to shortcut after demonstrating the loop.
The best window is a turn when opponents are tapped out or after they commit a spell — hold protection (a counter, Vexing Shusher) if the combo wins on the spot.
