Wernog, Rider's Chaplain

Time Sieve

Academy Manufactor

Soulherder

How it works

1. At the beginning of your end step, Soulherder's second ability triggers, blinking Wernog.
2. When Wernog leaves and enters the battlefield, it triggers twice and Soulherder's first ability triggers once.
3. Resolve both Wernog triggers, creating at least two Clue, two Food and two Treasure artifact tokens.
4. Resolve the Soulherder trigger, putting a +1/+1 counter on it.
5. Activate Time Sieve by tapping it and sacrificing five artifacts, causing you to take an extra turn after this one.
6. Repeat each turn.
