By enchanting Stone-Seeder Hierophant with Freed from the Real, you establish a self-sustaining engine where the Shaman can tap to untap Lotus Field, then use a sliver of the mana generated by that massive land to untap herself. While Lotus Field typically slows you down by forcing you to sacrifice two lands upon entry and entering the battlefield tapped, its ability to tap for three mana of any color completely subsidizes this loop. Because Freed from the Real only demands a single blue mana to untap its host, you are left with a net gain of two mana of any color with every single iteration.
