Timestream Navigator + Recruiter of the Guard + Conjurer's Closet

Timestream Navigator

Recruiter of the Guard

Conjurer's Closet

How it works

1. Activate Timestream Navigator by paying 2, tapping it and putting it from the battlefield onto the bottom of your library, causing you to take an extra turn after this one.
2. Blink Recruiter of the Guard using Conjurer's Closet.
3. When Recruiter of the Guard enters, it triggers, searching your library for Timestream Navigator and putting it into your hand.
4. Cast Timestream Navigator by paying 1.
5. Repeat each turn.

This ingenious loop gives you absolute dominion over time by continuously recycling Timestream Navigator to take infinite extra turns. Once you have achieved the city's blessing, Timestream Navigator tucks itself to grant you that extra turn, leaving you in desperate need of a way to find it again. That is where Conjurer's Closet steps in during your end step to blink Recruiter of the Guard, which uses its enter-the-battlefield ability to tutor Timestream Navigator right back to your hand so you can cast it anew each cycle.
