Overlord of the Hauntwoods + Displacer Kitten + Tiller Engine + Panharmonicon + Flickering Ward

Overlord of the Hauntwoods

Displacer Kitten

Tiller Engine

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.
4. When the Everywhere land tokens enter the battlefield, Tiller Engine triggers, untapping them.
5. Resolve the Flickering Ward spell.
6. Activate the two Everywhere tokens by tapping them, adding .
7. Activate Flickering Ward by paying , returning it from the battlefield to your hand.
8. Repeat.

This elegant loop relies on Displacer Kitten turning every noncreature spell into a blink engine, using Flickering Ward as our infinitely recastable trigger. When we cast the Ward, the Kitten blinks Overlord of the Hauntwoods, and thanks to Panharmonicon doubling its entry trigger, the Overlord floods our board with a pair of Everywhere land tokens. Those lands enter tapped, which immediately wakes up Tiller Engine to untap them so they can be tapped right back for the white mana we need to bounce Flickering Ward back to our hand. We can repeat this process endlessly, generating an unstoppable cascade of landfall triggers, storm count, and general magical alchemy.
