Breath of Fury + Concordant Crossroads + Seraphic Steed

Breath of Fury

Concordant Crossroads

Seraphic Steed

How it works

1. Declare the creature with Breath of Fury attached and Seraphic Steed as attackers.
2. Seraphic Steed triggers, creating a creature token.
3. Deal combat damage using the creature that has Breath of Fury attached.
4. 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.
5. Repeat each combat phase.

This brilliant loop turns your team into an unstoppable war machine by chaining extra attack steps infinitely. With Concordant Crossroads granting haste to everything the moment it hits the board, your newly minted forces can jump straight into the fray without waiting. Seraphic Steed provides the ongoing fuel for the engine, spawning a fresh 3/3 white Angel token every time it charges into battle while saddled. Finally, Breath of Fury orchestrates the entire cycle: whenever the creature wearing the Aura connects for combat damage, it sacrifices itself to pass the enchantment onto that newly created Angel token, simultaneously untapping all your creatures and granting you an additional combat phase to do it all over again.
