How it works
Declare your commander and the creature with Breath of Fury attached as attackers.
We Ride at Dawn's second ability triggers, creating a 1/1 Mercenary 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 Mercenary 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 ingenious loop relies on turning your commander's attacks into an endless chain of combat phases by continually sacrificing and moving Breath of Fury onto the fresh fodder it provides. While Concordant Crossroads ensures your newly created tokens can jump straight into the fray with haste, We Ride at Dawn sets up the entire engine by churning out a 1/1 red Mercenary creature token every single time your commander declares an attack. The resulting setup effortlessly fuels infinite combat damage, untaps, and sacrifice triggers by bouncing the Aura back and forth between your attackers and the newly minted tokens.
