This clever loop relies on Eldrazi Displacer to repeatedly reset Edgar, Master Machinist, allowing you to continually recast the artifacts you sacrifice to Krark-Clan Ironworks. Whenever you sacrifice Cathodion to the Ironworks, its death trigger conveniently supplies the exact colorless mana needed to fuel the Displacer's activation and pay for Edgar's graveyard-casting ability. Meanwhile, Armor Wars quietly sets the stage by reducing your artifact spell costs with its second chapter, while Edgar and the Saga's final chapter leverage the highest mana value among your artifacts to scale your offensive pressure.
