Aya of Alexandria + Breath of Fury + Encroaching Mycosynth + Frostcliff Siege

Aya of Alexandria

Breath of Fury

Encroaching Mycosynth

Frostcliff Siege

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.

By turning every permanent you control into an artifact with Encroaching Mycosynth, you ensure that Aya of Alexandria, your Assassin tokens, and even the enchanted creature itself all count as historic permanents to trigger additional rewards. Frostcliff Siege fuels your engine by granting your entire board haste, trample, and crucial card draw on every single combat. You then loop Breath of Fury by attacking, sacrificing your creature to attach the Aura to the newly created Assassin token, and untapping your board to repeat the process across infinite additional combat phases.
