This ingenious loop transforms your own graveyard into an engine of endless rebirth, centered around Yedora, Grave Gardener's unique ability to resurrect fallen nontoken creatures as face-down Forest lands. To turn those lands back into active pieces, Hauntwoods Shrieker steps in with its ability to pay to flip them face up, while Thermopod provides the crucial sacrifice outlet that feeds the loop and generates red mana. By continuously sacrificing Thermopod, letting Yedora return it as a land, tapping it for green mana, and using Hauntwoods Shrieker to turn it face up again, you generate an infinite stream of death triggers, creature sacrifices, and landfall events.
