Breath of Fury + Treasury Thrull + Aluren + Mass Hysteria

Breath of Fury

Treasury Thrull

Aluren

Mass Hysteria

How it works

1. Declare Treasury Thrull and the creature with Breath of Fury attached as attackers.
2. Treasury Thrull triggers, returning a creature card with mana value 3 or less from your graveyard to your hand.
3. Cast the creature by paying 0 due to Aluren.
4. Deal combat damage using the creature that has Breath of Fury attached.
5. Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the creature with mana value 3 or less, then causing you to untap all creatures you control and to get an additional combat phase after this one.
6. Repeat each combat phase.

This clever loop relies on Breath of Fury to endlessly chain combat phases by sacrificing its host upon dealing combat damage to a player, moving to a fresh creature, and untapping your entire board. Mass Hysteria ensures your newly entering threats never have to wait to attack, while Aluren breaks the economy wide open by letting you recast the small creatures you cycle through for free at instant speed. As the engine spins, Treasury Thrull does double duty by swinging alongside your attackers to continuously regrow those sacrificed or discarded low-cost creatures right back to your hand, fueling the endless assault.
