Breath of Fury + Adeline, Resplendent Cathar + Purphoros, Bronze-Blooded

Breath of Fury

Adeline, Resplendent Cathar

Purphoros, Bronze-Blooded

How it works

1. Declare the creature with Breath of Fury attached and Adeline as attackers.
2. Adeline 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 loop relies on passing Breath of Fury to a fresh attacker every turn, and Adeline, Resplendent Cathar provides the exact fuel you need by generating a new creature token every single time you declare attackers. As the enchanted creature connects for combat damage, Breath of Fury triggers its sacrifice and reattachment clause, moving itself onto Adeline's newly minted Human token while untapping your entire board for an extra combat phase. Meanwhile, Purphoros, Bronze-Blooded quietly ensures your newly generated tokens and any alternate attackers can immediately join the fray by granting the entire team haste, closing out the game through an endless series of combat steps.
