How it works
Deal combat damage using the creature that has Breath of Fury attached and Drider, triggering Breath of Fury and Drider.
Resolve the Drider 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 relentless loop relies on chaining extra combat steps by continuously passing an Aura from a falling creature to a fresh body. When your attacker bearing Breath of Fury connects, it forces you to sacrifice that creature—a devastating cost neatly sidestepped because Urabrask the Hidden ensures your entire team is ready to swing again with haste. Meanwhile, Drider triggers alongside the Aura's sacrifice, replacing your fallen attacker with a Spider token that is immediately ready to receive Breath of Fury in the next phase.
