Breath of Fury + Mass Hysteria + Threefold Thunderhulk

Breath of Fury

Mass Hysteria

Threefold Thunderhulk

How it works

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

This brilliant loop leverages Mass Hysteria to give your entire army haste right out of the gate, allowing newly minted attackers to immediately join the fray. You start by sending Threefold Thunderhulk and the creature enchanted by Breath of Fury into battle together, triggering the Thunderhulk to flood the board with Gnome tokens. When the enchanted creature connects for combat damage, Breath of Fury triggers to sacrifice it, hops onto one of the fresh Gnomes, and grants you an untap alongside an extra combat phase. Because every creature can attack anew and spawn even more Gnomes with each iteration, you generate an unstoppable chain of infinite combat phases and cascading token triggers.
