Breath of Fury + Tana, the Bloodsower + Roar of Resistance

Breath of Fury

Tana, the Bloodsower

Roar of Resistance

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.

By enchanting Tana, the Bloodsower with Breath of Fury, you set up an engine where dealing combat damage to a player lets Tana sacrifice herself to trigger the Aura's relocation and untap your board, sliding Breath of Fury onto one of the freshly spawned Saproling tokens created by Tana's damage trigger. Roar of Resistance immediately steps in to grant those new tokens haste so they can charge right into the next combat phase, while its optional mana payment can even pump your attacking creatures for extra lethality. As the new creature host attacks and deals damage, the loop repeats indefinitely, chaining bonus combat phases and sacrificing tokens to generate endless death and sacrifice triggers.
