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 vicious loop turns an ordinary attack into an endless sequence of assaults, fueled by the relentless pressure of Adeline, Resplendent Cathar. Because Mass Hysteria grants haste to everything on your board, every new 1/1 Human token Adeline creates upon attacking is immediately ready to receive the shifting burden of Breath of Fury. When your enchanted creature connects for combat damage, Breath of Fury sacrifices it to leap onto that fresh token, untapping your entire team and granting you another combat phase to repeat the massacre.
