This clever loop transforms your graveyard into a self-sustaining mana engine by turning death into new growth. With Yedora, Grave Gardener waiting in the wings, sacrificing Coral Trickster to Phyrexian Altar doesn't send it to the bin for good—instead, Yedora plucks it right back onto the battlefield as a face-down Forest land. Because this reborn land can tap for its own green mana, and you can leverage Coral Trickster's morph ability (paid for with the blue mana generated by the Altar) to turn it back face up, you can constantly reset the trickster to repeat the process. The result is an endless cascade of mana, sacrifice, and landfall triggers fueled entirely by the clever interplay of these three cards.
