Overlord of the Hauntwoods

Displacer Kitten

Spelunking

Panharmonicon

Flickering Ward

How it works

1. Cast Flickering Ward by paying .
2. Displacer Kitten triggers, blinking Overlord of the Hauntwoods.
3. When Overlord of the Hauntwoods enters the battlefield, it triggers twice, creating two tapped Everywhere land tokens, which enter untapped due to Spelunking.
4. Resolve the Flickering Ward spell.
5. Activate the two Everywhere tokens by tapping them, adding .
6. Activate Flickering Ward by paying , returning it from the battlefield to your hand.
7. Repeat.

This clever loop centers around Displacer Kitten, which acts as the engine by untapping and resetting your permanents whenever you cast a noncreature spell like Flickering Ward. To make the loop self-sustaining, Spelunking ensures that the Everywhere land tokens created by Overlord of the Hauntwoods enter the battlefield untapped, allowing those lands to immediately tap for the exact mana needed to bounce Flickering Ward back to your hand. Meanwhile, Panharmonicon doubles the entry triggers of Overlord of the Hauntwoods, flooding the board with every basic land type and generating an overwhelming surplus of resources.
