How it works
Declare the creature with Breath of Fury attached and Yore-Tiller Nephilim as attackers.
Yore-Tiller Nephilim triggers, returning a creature card from your graveyard to the battlefield tapped and attacking.
Deal combat damage to an opponent using the creature with Breath of Fury attached.
Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to another creature, untap all creatures you control and get an additional combat phase after this one.
Repeat each combat phase.
This elegant engine uses Yore-Tiller Nephilim to continuously resurrect your sacrificed creatures straight into the fray, while Anger ensures your newly untapping forces can swing immediately without waiting around. Every time your designated threat connects for combat damage, Breath of Fury triggers to sacrifice that creature, untap your entire board, and leapfrog onto a fresh attacker to grant you an extra combat phase. By looping this sequence over and over, you turn a single opening into an unstoppable chain of infinite combats and devastating triggers.
