This loop relies on Myrkul, Lord of Bones to transform your dying creatures into enchantment copies, effectively turning your graveyard into a factory of permanent enchantments. Once Ondu Spiritdancer meets its demise and is reborn as an enchantment copy, its entrance triggers itself to replicate and simultaneously fuels Eidolon of Blossoms's constellation ability to draw you a card. Because the new token copy is *also* an enchantment entering the battlefield, it triggers another chain of copying and card drawing, allowing you to cycle through your entire deck while generating an overwhelming board presence of enchantment creatures.
