How it works
Deal combat damage using the creature that has Breath of Fury attached and Precinct Captain, triggering Breath of Fury and Precinct Captain.
Resolve the Precinct Captain trigger, creating a creature token.
Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to a creature token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
Repeat each combat phase.
This loop transforms a modest combat step into an endless sequence of phases by turning your attacking creatures into a self-sustaining engine. When Precinct Captain deals combat damage alongside the creature enchanted with Breath of Fury, the Captain generates a fresh 1/1 white Soldier creature token to feed the Aura's insatiable hunger. Meanwhile, Fervor grants your newly minted tokens haste so they are immediately ready to charge into battle the moment Breath of Fury untaps your board and grants you an additional combat phase. You simply sacrifice the creature currently bearing the Aura, move it to the latest Soldier token, and repeat the carnage indefinitely for infinite combat phases and damage.
