Overlord of the Hauntwoods + Displacer Kitten + Crown of Flames + Panharmonicon + Archelos, Lagoon Mystic

Overlord of the Hauntwoods

Displacer Kitten

Crown of Flames

Panharmonicon

Archelos, Lagoon Mystic

How it works

1. Cast Crown of Flames 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 Archelos.
4. Resolve the Crown of Flames spell.
5. Activate the two Everywhere tokens by tapping them, adding .
6. Activate Crown of Flames by paying , returning it from the battlefield to your hand.
7. Repeat.

This ingenious loop turns a simple Aura into a massive mana and landfall engine by exploiting Displacer Kitten's blink trigger every time you cast a noncreature spell. While Crown of Flames is cheap to cast and bounce back to your hand using its own activation, Panharmonicon doubles down on Overlord of the Hauntwoods so that each blink yields double the Everywhere land tokens. Finally, Archelos, Lagoon Mystic ensures these new tokens completely bypass their normal restriction by entering the battlefield untapped, providing all the red mana you need to pay for the Crown's loop indefinitely.
