This enchanting loop uses Whip Silk as the recurring noncreature engine that keeps Displacer Kitten constantly blinking Overlord of the Hauntwoods. Because Panharmonicon doubles the Overlord's entry triggers, every single iteration floods the board with Everywhere land tokens. Thanks to Horizon Explorer, those newly minted lands bypass their usual restrictions to enter the battlefield completely untapped, providing more than enough mana to infinitely bounce and recast the Whip Silk.
