Breath of Fury + Origin of the Hidden Ones + Mass Hysteria

Breath of Fury

Origin of the Hidden Ones

Mass Hysteria

How it works

1. At the beginning of your precombat main phase, Origin of the Hidden Ones triggers, putting a lore counter on it.
2. Origin of the Hidden Ones' third chapter ability triggers, causing you to create an Assassin token whenever an Assassin attacks this turn and sacrifice Origin of the Hidden Ones.
3. Declare the creature with Breath of Fury attached, and at least one Assassin if the creature with Breath of Fury attached isn't an Assassin, as attackers.
4. Origin of the Hidden Ones triggers, creating a 1/1 Assassin creature token that's tapped and attacking.
5. Deal combat damage using the creature that has Breath of Fury attached.
6. Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the Assassin token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
7. Repeat from step 3 each combat phase.

This loop transforms a modest army into an endless succession of attacks, fueled by the relentless pressure of Breath of Fury. Mass Hysteria ensures that every newly created token can immediately charge into battle without waiting to summon sickness, which is vital when chaining extra combat phases together. As you smash into your opponent, Origin of the Hidden Ones provides a fresh Assassin token via its third chapter ability each time, giving Breath of Fury a brand-new host to latch onto after you sacrifice the previous creature. By repeatedly dealing combat damage and moving the Aura to the newly spawned attacker, you untap all your creatures over and over again to sustain the infinite assault.
