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 relentless loop centers around Breath of Fury attached to an attacking creature, which triggers whenever that creature deals combat damage to a player, forcing you to sacrifice it, untap your team, and take an additional combat phase while sliding the Aura onto a fresh creature. That fresh fuel is conveniently provided by We Ride at Dawn, which churns out a 1/1 red Mercenary creature token every time your commander attacks to reliably catch Breath of Fury on the rebound. Meanwhile, Urabrask the Hidden ensures that your newly untapping board and incoming tokens waste no time, granting haste so everyone can immediately charge back into the red zone for infinite combat steps.
