How it works
Declare the creature with Breath of Fury attached and Pugnacious Pugilist as attackers.
Pugnacious Pugilist triggers, creating a creature token.
Deal combat damage using the creature that has Breath of Fury attached.
Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the creature token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
If the sacrificed creature was a Devil token, it triggers when it dies, dealing 1 damage to any target.
Repeat each combat phase.
This brilliant loop relies on enchanting a disposable attacker with Breath of Fury so that when it connects for combat damage, you sacrifice it to untap your board and chain directly into an extra combat phase. To keep the chain fueled infinitely, you need a steady stream of sacrificial fodder, which is solved by Pugnacious Pugilist generating a tapped and attacking token every time it swings. Meanwhile, Yarus, Roar of the Old Gods ties the battlefield together by granting your entire board haste so they can immediately rush into the next combat phase without missing a beat.
