This clever loop turns the cycle of life and death into a perpetual motion machine by turning a basic land into a creature that can endlessly sacrifice itself. Thanks to Yedora, Grave Gardener, any nontoken creature that dies immediately returns to the battlefield face down as a new Forest land, effectively bypassing the graveyard. You then animate that very same land using Kamahl, Fist of Krosa, turning it back into a 1/1 creature so it's vulnerable once more. Finally, Zuran Orb provides the necessary sacrifice outlet to send the land-creature packing while padding your life total in the process, allowing you to feed the loop as many times as you desire for endless triggers.
