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.
Repeat each combat phase.
This ingenious loop turns an opponent's own library into an endless engine of war by attaching Breath of Fury to the fresh face-down creature created by Orochi Soul-Reaver's combat damage trigger. Because Fires of Yavimaya grants your entire board haste, the newly manifested card can immediately attack in the additional combat phase generated by Breath of Fury's sacrifice and reattachment effect. As the cycle repeats, Orochi Soul-Reaver ensures you continuously churn out Treasure tokens and fresh attackers, letting you chain infinite combat phases together until your opponents are entirely overwhelmed.
