Aya of Alexandria + Breath of Fury + Biotransference + Frostcliff Siege

Aya of Alexandria

Breath of Fury

Biotransference

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.

This clever loop hinges on the subtle synergy of **Biotransference**, which turns every creature you control into an artifact—making them all retroactively historic. This ensures that when **Aya of Alexandria** connects in combat alongside the creature enchanted by **Breath of Fury**, she rewards your strike by spawning a fresh Assassin token. When Breath of Fury forces you to sacrifice your attacker, you simply reattach the Aura to that newly minted Assassin, untapping your board and seizing an endless chain of extra combat phases. Meanwhile, **Frostcliff Siege** acts as your engine's ultimate catalyst; by choosing Temur, it grants your entire team haste and trample to start the carnage immediately, while choosing Jeskai turns your infinite strikes into an endless draw engine.
