Breath of Fury + Tana, the Bloodsower + Yarus, Roar of the Old Gods

Breath of Fury

Tana, the Bloodsower

Yarus, Roar of the Old Gods

How it works

1. Deal combat damage using the creature that has Breath of Fury attached and Tana, triggering Breath of Fury and Tana.
2. Resolve the Tana trigger, creating at least one creature token.
3. Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to a creature token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
4. Repeat each combat phase.

This loop turns a single successful attack into an endless chain of combat phases by feeding Tana, the Bloodsower's combat damage trigger to continuously supply a fresh target for Breath of Fury. When the enchanted creature connects with a player, Breath of Fury forces its sacrifice but immediately relocates to one of the newly minted tokens from Tana, simultaneously untapping your board for the extra combat granted by its resolution. Meanwhile, Yarus, Roar of the Old Gods plays a crucial foundational role by granting your entire army haste so that every newly generated creature token can immediately race into the red zone during the next phase.
