This classic two-card engine relies on Freed from the Real enchanting Ley Druid to turn mana generation into a self-sustaining loop. By tapping Ley Druid to untap Dimir Aqueduct, you can produce both blue and black mana, then use a portion of that blue mana to untap the Druid via Freed from the Real. Because Dimir Aqueduct taps for two mana while the untap effects cost only one blue to loop, this intricate dance generates an infinite surplus of black mana alongside unlimited uses of your land's dual mana production.
