This explosive loop centers on Dargo, the Shipwrecker and its unique knack for cheap recursion from the command zone, fueled entirely by the mana-generating engine of Ashnod's Altar. Because Dargo costs {2} less for each other artifact or creature you've sacrificed this turn—and its own commander tax can be completely bypassed by utilizing its massive cost-reduction—you can recast it over and over for a mere single red mana. To sustain that red mana requirement, Birgi, God of Storytelling sits on the battlefield waiting to generate {R} every single time you cast Dargo from the command zone. The result is a self-sustaining loop that simultaneously generates infinite colorless mana via the Altar while stacking up infinite creature sacrifices, storm count, and death triggers.
