Breath of Fury

Harnessed Snubhorn

Encroaching Mycosynth

Sculpting Steel

Urabrask the Hidden

How it works

1. Deal combat damage to an opponent using Harnessed Snubhorn, triggering it and Breath of Fury.
2. Resolve the Harnessed Snubhorn trigger, returning Sculpting Steel from your graveyard to the battlefield as a copy of Harnessed Snubhorn.
3. Resolve the Breath of Fury trigger, causing you to sacrifice Harnessed Snubhorn, then attach Breath of Fury to Sculpting Steel, then causing you to untap all creatures you control and to get an additional combat phase after this one.
4. Move to your next combat phase.
5. Deal combat damage to an opponent using Sculpting Steel, triggering it and Breath of Fury.
6. Resolve the Sculpting Steel trigger, returning Harnessed Snubhorn from your graveyard to the battlefield.
7. Resolve the Breath of Fury trigger, causing you to sacrifice Sculpting Steel, then attach Breath of Fury to Harnessed Snubhorn, then causing you to untap all creatures you control and to get an additional combat phase after this one.
8. Move to your next combat phase.
9. Repeat.

This brilliant loop hinges on turning your entire board into artifacts with Encroaching Mycosynth, allowing Sculpting Steel to enter the battlefield from the graveyard as a fresh copy of Harnessed Snubhorn. As these two creatures take turns dealing combat damage, each one alternates pulling the other back out of the graveyard while Breath of Fury sacrifices the current attacker to leapfrog onto the newcomer. Urabrask the Hidden ensures that whichever dinosaur is resurrected can immediately charge into battle without waiting, granting you an endless parade of combat phases and devastating triggers.
