This elegant loop turns the combat step into a relentless engine of chronological control, chaining infinite extra turns by recycling a single artifact. It all begins when you march your commanders into battle: thanks to Guild Artisan's passive ability, attacking the player with the highest life total instantly floods your board with four Treasure tokens. You then supplement those sacrifices by tapping Time Sieve alongside the Treasures, feeding the artifact directly to its own activation cost to seize an extra turn. Meanwhile, Silas Renn, Seeker Adept waits to connect for combat damage, using deathtouch to dissuade blockers before taking advantage of its triggered ability to pluck Time Sieve right back out of the graveyard and recast it for the next cycle.
