This intricate engine relies on Ashaya, Soul of the Wild to transform your nontoken creatures into Forests, turning every creature drop into a land drop for landfall purposes. With Stone-Seeder Hierophant on the board, playing a creature triggers both its own land-status abilities and untaps the Hierophant, while Simic Growth Chamber provides the necessary mana and a bouncing mechanism to keep the loop going. By leveraging Dream Stalker to continually re-enter the battlefield and reset the loop, you generate an endless cascade of creature leaves-the-battlefield and enters-the-battlefield triggers, alongside infinite storm count and landfall triggers.
