This intricate loop revolves around generating infinite resources by continuously recycling Cathodion through the graveyard. Krark-Clan Ironworks provides the initial sacrifice outlet to turn Cathodion into raw mana, which conveniently triggers Cathodion's own death ability to net a surplus of colorless mana. Meanwhile, Starnheim Courser and Edgar, Master Machinist work behind the scenes to make this possible: Starnheim Courser reduces the cost to recast Cathodion from the graveyard, while Edgar allows you to keep pulling it back once per turn. Finally, Eldrazi Displacer spends that generated mana to blink Edgar, clearing the once-per-turn restriction so the cycle can repeat indefinitely.
