How it works
Deal combat damage using the creature that has Breath of Fury attached.
Breath of Fury and Orochi Soul-Reaver trigger.
Resolve the Orochi Soul-Reaver trigger, creating a Treasure token and causing you to manifest the top card of the damaged opponent's library.
Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the manifested card, then causing you to untap all creatures you control and to get an additional combat phase after this one.
