How it works
Deal combat damage to an opponent using Living Hive and the creature with Breath of Fury attached.
Breath of Fury and Living Hive trigger.
Resolve the Living Hive trigger, creating six 1/1 Insect creature tokens.
Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to an Insect token, untap all creatures you control and get an additional combat phase after this one.
Repeat each combat phase.
Deal combat damage using the creature that has Breath of Fury attached and Living Hive, triggering Breath of Fury and Living Hive.
Resolve the Living Hive trigger, creating at least one creature token.
Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to a 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 chaotic sequence turns a relentless swarm into an endless chain of attack phases, fueled by the sheer explosive power of Living Hive connecting with an opponent. Because Concordant Crossroads grants haste to everything the moment it enters or untaps, your freshly spawned token army doesn't have to wait around to join the assault. You simply sacrifice the creature currently bearing Breath of Fury to pay its trigger cost, immediately reattaching the Aura to one of the newly minted insects to untap your entire board and seize another combat phase.
