This clever loop turns your entire creature base into a self-sustaining engine of resurrection by turning the battlefield into a graveyard’s revolving door. Thanks to Ashaya, Soul of the Wild, every nontoken creature you cast automatically enters as a Forest land in addition to its creature type, while Celestial Dawn steps in to ensure those lands are also treated as Plains. That double-classification is the linchpin: every time a creature enters, it satisfies Emeria Shepherd's landfall ability for a Plains, letting you bypass your graveyard and drop a nonland permanent directly back onto the battlefield. Before that return trigger resolves, you simply sacrifice the newly arrived creature to Viscera Seer, fueling a scry and feeding the loop so you can repeat the cycle infinitely.
