How it works
Declare the creature with Breath of Fury attached and Threefold Thunderhulk as attackers.
Threefold Thunderhulk triggers, creating a creature token.
Deal combat damage using the creature that has Breath of Fury attached.
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.
Repeat each combat phase.
This loop relies on the relentless, self-sustaining army generated by Threefold Thunderhulk, whose sheer power fuels an endless chain of extra combat phases. By enchanting one of your attackers with Breath of Fury, you turn every successful strike into a catalyst that sacrifices the current bearer, moves the Aura to a fresh Gnome token, untaps your entire board, and grants you another combat step. Meanwhile, Maelstrom Wanderer ties the whole strategy together by granting permanent haste to every creature you control, ensuring your newly minted tokens can charge straight into battle the moment they arrive.
