How it works
Declare the creature with Breath of Fury attached and The Unbeatable Squirrel Girl as attackers.
The Unbeatable Squirrel Girl 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 vicious loop uses Urabrask the Hidden to give your army the haste they need to immediately jump into the fray alongside The Unbeatable Squirrel Girl, who continuously churns out fresh Squirrel tokens both upon entering and every time she attacks. You attach Breath of Fury to one of these tokens, and the moment it connects for combat damage, the Aura sacrifices it to leap onto a newly generated token while untapping your entire squad and granting you an additional combat phase. Because Urabrask the Hidden ensures your freshly untapped attackers can keep charging in without waiting, Breath of Fury can endlessly chain extra combats and sacrifice triggers as long as you have a creature to feed it.
