Azusa, Lost but Seeking + Magistrate's Scepter + Evolution Sage + Simic Growth Chamber

Azusa, Lost but Seeking

Magistrate's Scepter

Evolution Sage

Simic Growth Chamber

How it works

1. Play Simic Growth Chamber.
2. When Simic Growth Chamber enters the battlefield, it and Evolution Sage trigger.
3. Resolve the Simic Growth Chamber trigger, returning it from the battlefield to your hand.
4. Resolve the Evolution Sage trigger, putting a charge counter on Magistrate's Scepter.
5. Repeat from step 1 until Magistrate's Scepter has four or more charge counters on it.
6. Activate Magistrate's Scepter's second ability by tapping it and removing three charge counters from it, causing you to take an extra turn after this one.
7. Repeat each turn.

By leveraging Azusa, Lost but Seeking to replay Simic Growth Chamber turn after turn, we can repeatedly trigger Evolution Sage's landfall ability to proliferate the charge counters on Magistrate's Scepter. Because Simic Growth Chamber bounces itself back to your hand upon entry, it conveniently sets up the exact land you need to replay for the next trigger while generating mana. Once Evolution Sage's repeated proliferation pushes Magistrate's Scepter to three or more charge counters, you simply cash them in for infinite extra turns, locking your opponents out of the game entirely.
