Breath of Fury + Squee, Dubious Monarch + Yarus, Roar of the Old Gods

Breath of Fury

Squee, Dubious Monarch

Yarus, Roar of the Old Gods

How it works

1. Declare the creature with Breath of Fury attached and Squee as attackers.
2. Squee 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.

By enchanting one of your attackers with Breath of Fury, you set up a loop where dealing combat damage forces you to sacrifice that creature and jump the Aura to a new host, untapping your entire board and granting an extra combat phase in the process. To keep this engine fueled infinitely, Squee, Dubious Monarch steps in by automatically churning out a fresh Goblin token every time he attacks, giving Breath of Fury a brand-new vessel to attach to over and over again. Meanwhile, Yarus, Roar of the Old Gods quietly accelerates your strategy by granting haste to your team so they can strike immediately during each newly generated combat step, while also capitalizing on any deaths and face-down action if needed.
