Overlord of the Hauntwoods + Displacer Kitten + Stone-Seeder Hierophant + Crown of Flames + Panharmonicon

Overlord of the Hauntwoods

Displacer Kitten

Stone-Seeder Hierophant

Crown of Flames

Panharmonicon

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.
4. When the Everywhere land tokens enter the battlefield, Stone-Seeder Hierophant triggers that many times.
5. Resolve the first trigger, untapping Stone-Seeder Hierophant.
6. Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping an Everywhere token.
7. Repeat from step 5 for the remaining trigger.
8. Resolve the Crown of Flames spell.
9. Activate the two Everywhere tokens by tapping them, adding .
10. Activate Crown of Flames by paying , returning it from the battlefield to your hand.
11. Repeat.

This ingenious loop relies on a brilliant dance of triggers and recursion, powered entirely by casting and bouncing Crown of Flames to continuously fuel Displacer Kitten's blink ability. Each time Crown of Flames is cast, the Kitten blinks Overlord of the Hauntwoods, whose entry triggers are doubled by Panharmonicon to flood the board with Everywhere land tokens. These newly arriving lands trigger Stone-Seeder Hierophant, creating a flurry of untap opportunities that allow you to constantly refresh your mana and tap the very Everywhere lands you just created to keep the engine going.
