How it works
Declare the creature with Breath of Fury attached and Squee as attackers.
Squee 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 clever loop turns Squee, Dubious Monarch into a relentless, self-sustaining engine of war by leveraging Gimli's Reckless Might to ensure your board is always ready to strike. Each time your enchanted creature connects, Breath of Fury triggers to sacrifice it, untap your team, and hot-swap itself onto the fresh 1/1 Goblin token generated by Squee's attack trigger. Because Gimli's Reckless Might generously grants all your creatures haste, that newly minted token can immediately charge into the next combat phase granted by Breath of Fury. By repeating this process infinitely, you cycle through endless combat phases, generating an unstoppable cascade of damage, sacrifices, and enters-the-battlefield triggers.
