How it works
Activate Walking Atlas by tapping it, putting Guildless Commons from your hand onto the battlefield.
Guildless Commons enters the battlefield, triggering itself and the permanent with a landfall ability.
Resolve the Guildless Commons trigger, returning it from the battlefield to your hand.
Resolve the landfall trigger, creating a creature token.
Deal combat damage to an opponent with the creature that has Breath of Fury attached.
Breath of Fury triggers, causing you to sacrifice the creature it is attached to and then attach Breath of Fury to the creature token from step 4, untap all creatures you control, and get an additional combat phase after this one.
Repeat each combat phase.
This fascinating loop centers on Breath of Fury's ability to grant infinite combat phases by sacrificing an attacker to chain the Aura onto a fresh creature and untap your board. To sustain this, Walking Atlas provides the crucial engine work to repeatedly deploy lands from your hand, while Guildless Commons bounces itself right back to your hand upon entry to feed that deployment loop. Together, these pieces turn every extra combat phase into a repeatable cycle of land drops, token generation, and creature untaps that lets you steamroll your opponents with endless attacks.
