This classic mana-generation engine uses **Arbor Elf** to repeatedly untap a modified land, fueling a continuous loop. By enchanting a Forest with **Utopia Sprawl**, that land taps for an extra mana of a chosen color—in this case, blue—transforming the Arbor Elf's targeted untap into a net-positive mana exchange. To turn that extra blue mana back into action, **Pemmin's Aura** is enchanted directly onto the Arbor Elf, allowing you to spend the generated blue mana to untap the Elf itself. Together, these three interacting permanents create a closed loop that generates infinite green mana and infinite mana of whatever colors your Forests can produce.
