This charming loop transforms your entire board into an engine for infinite Elf tokens, utilizing Earthcraft and Presence of Gond to ping back and forth between creature generation and untapping. The true genius of the assembly lies in Ashaya, Soul of the Wild, whose passive ability turns every nontoken creature you control into a Forest land, allowing them to be targeted by Earthcraft's untap ability. Meanwhile, Rootpath Purifier ensures all your lands—and land cards in your library—are basic, fulfilling Earthcraft's strict requirement for the land you choose to untap.
