Tap at least five Assassins, Pirates and/or Vehicles you control, either by declaring them as attackers if they don't have vigilance or by using any other method.
At the beginning of your end step, Edward Kenway's first ability triggers, creating at least five Treasure tokens.
Activate Time Sieve by tapping it and sacrificing five Treasures, causing you to take an extra turn after this one.
Repeat each turn.
This brilliant loop turns your pirate crew's hard-earned plunder into the ultimate currency of time itself. By tapping five qualifying permanents—whether through combat or other means—Edward Kenway's end step trigger generates the exact quorum of five Treasure tokens required to fuel Time Sieve. Sacrificing those Treasures to Time Sieve grants you an extra turn, allowing you to untap, repeat the process, and lock your opponents out of the game entirely.
