How it works
Declare the creatures with Staff of Titania and Breath of Fury attached as attackers.
Staff of Titania triggers, creating a 1/1 Forest Dryad land creature token.
Deal combat damage using the creature that has Breath of Fury attached.
Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the Forest Dryad 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 ingenious loop starts by enchanting a creature with Breath of Fury and equipping it with Staff of Titania, ensuring that every time your attacker connects with an opponent, the staff automatically generates a fresh 1/1 Forest Dryad token to receive the Aura. Because Fervor grants all your creatures haste, the newly spawned Dryad can immediately step into the role of the sacrificial attacker for the next iteration. As Breath of Fury moves from the fallen creature to the new token, it untaps your entire board and grants you an endless sequence of additional combat phases to overwhelm your opponents.
