Breath of Fury + Tervigon + Tuktuk Rubblefort

Breath of Fury

Tervigon

Tuktuk Rubblefort

How it works

1. Deal combat damage using the creature that has Breath of Fury attached and Tervigon, triggering Breath of Fury and Tervigon.
2. Resolve the Tervigon 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 combat strike into an endless march of phases, fueled by Tervigon's massive Tyranid token generation whenever it deals combat damage to a player. Breath of Fury manages the heavy lifting of keeping the sequence alive, constantly sacrificing its host to reattach to one of those newly minted tokens while untapping your entire team. Meanwhile, Tuktuk Rubblefort provides the crucial haste needed so that every fresh token can immediately join the fray in the next combat phase, translating raw damage into an unstoppable, infinitely repeating cycle.
