How it works
Declare Warchanter Skald and the creature with Breath of Fury attached as attackers.
Warchanter Skald triggers, creating a 2/1 Dwarf Berserker creature token.
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 the Dwarf Berserker token, untap all creatures you control and to get an additional combat phase after this one.
Repeat each combat phase.
This loop turns your attack steps into an infinite engine by feeding fresh bodies right back into the enchantment's demands. With Mass Hysteria granting every new arrival haste, Warchanter Skald is free to tap for a 2/1 Dwarf Berserker token the moment it joins the offensive line. When your primary attacker deals combat damage, Breath of Fury sacrifices that creature to untap your board, sliding over to enchant the newly minted Dwarf and granting you an extra combat phase. By bouncing the Aura from one sacrificial lamb to the next, you continually reset your combat steps while Warchanter Skald keeps the token production rolling.
