When Ancestral Statue enters the battlefield, it and Surge Conductor trigger.
Resolve the Ancestral Statue trigger, returning it from the battlefield to your hand.
Resolve the Surge Conductor trigger, putting a charge counter on Magistrate's Scepter.
Repeat from step 1 two additional times.
Activate Magistrate's Scepter's second ability by tapping and removing three charge counters from it, causing you to take an extra turn after this one.
Repeat each turn.
This clever loop leverages Ancestral Statue as a self-bouncing engine that endlessly recasts itself to feed your board state. Every time the Statue enters, Surge Conductor steps in to proliferate, quietly slipping an extra charge counter onto Magistrate's Scepter alongside its usual accumulation. Once the Scepter holds three counters, you can cash them in to take infinite extra turns, locking your opponents out of the game entirely.
