Breath of Fury + Mass Hysteria + Seraphic Steed

Breath of Fury

Mass Hysteria

Seraphic Steed

How it works

1. Declare the creature with Breath of Fury attached and Seraphic Steed as attackers.
2. Seraphic Steed 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 loop turns a relentless cycle of extra combat phases into a win by continuously recycling a single Aura through an army of mounts and tokens. Mass Hysteria ensures your newly created tokens can attack immediately without waiting around for summoning sickness. Seraphic Steed provides the vital creature tokens each time it attacks while saddled, fueling a fresh target for Breath of Fury to attach to when the previous bearer deals combat damage and is sacrificed. By constantly untapping all your creatures and granting endless additional combat phases, Breath of Fury keeps the chain going as long as you have a body ready to receive it.
