Aya of Alexandria + Breath of Fury + Urabrask the Hidden + Encroaching Mycosynth

Aya of Alexandria

Breath of Fury

Urabrask the Hidden

Encroaching Mycosynth

How it works

1. Deal combat damage using the creature that has Breath of Fury attached.
2. Breath of Fury and Aya of Alexandria trigger.
3. Resolve the Aya of Alexandria trigger, creating a 1/1 Assassin creature token.
4. Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the Assassin 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 loop turns your team into an endless army by turning every single creature into a historic threat thanks to Encroaching Mycosynth, which ensures that even regular creature tokens like the ones made by Aya of Alexandria count as historic. When your enchanted creature connects in combat, Breath of Fury triggers to sacrifice it and hop over to the newly minted Assassin token, seamlessly recycling the aura. Meanwhile, Urabrask the Hidden ensures the freshly spawned tokens can immediately jump into the fray with haste, allowing you to chain infinite combat phases and untap steps without missing a beat.
