How it works
Declare the creature with Breath of Fury attached and Adeline as attackers.
Adeline 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.
Repeat each combat phase.
This brilliant loop feeds directly off Adeline, Resplendent Cathar's attack trigger, which reliably floods the board with a fresh Human token every single time you declare attackers. That newly created token serves as the critical fresh vessel for Breath of Fury, absorbing the Aura when the originally enchanted creature sacrifices itself upon dealing combat damage to a player. Meanwhile, Cyclops of Eternal Fury quietly grants haste to ensure your entire army—including the newly dropped tokens—can swing immediately during the endless string of extra combat phases generated by Breath of Fury's recurring trigger.
