How it works
Declare the creature with Breath of Fury attached and Grave Titan as attackers.
Grave Titan 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 engine transforms a single successful strike into an endless parade of combat phases, fueled by Grave Titan and its relentless army of Zombie tokens. With Fervor granting your team haste, newly spawned tokens can immediately charge into battle alongside the creature bearing Breath of Fury. Every time that enchanted attacker connects with a player, Breath of Fury triggers to sacrifice it, hops over to a fresh Zombie token to keep the cycle going, and untaps your entire team to do it all over again in an additional combat phase.
