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 clever loop revolves around Breath of Fury granting an extra combat phase every time its enchanted host deals combat damage to a player. To keep the chain unbroken, Precinct Captain does double duty: it steps in as a fresh target to inherit Breath of Fury when the previous attacker is sacrificed, and its first-strike combat damage triggers right on time to churn out a 1/1 white Soldier creature token. Meanwhile, Hammer of Purphoros ensures these freshly minted tokens and any untapped creatures can immediately charge into battle with haste.
