Activate Three Tree City's second ability by paying 2 and tapping it, adding at least four mana of any color.
Activate Meloku by paying 1 and returning Three Tree City from the battlefield to your hand, creating a 1/1 Illusion creature token.
Activate High Market's second ability by tapping it and sacrificing the Illusion.
When the Illusion dies, Sakashima of a Thousand Faces and Minn's second abilities trigger.
Holding priority, activate Meloku by paying 1 and returning High Market from the battlefield to your hand, creating a 1/1 Illusion creature token.
Resolve the Sakashima of a Thousand Faces and Minn triggers, putting Three Tree City and High Market from your hand onto the battlefield, choosing any creature type for Three Tree City that you control at least four creatures of.
Repeat.
This clever loop turns the token-generating prowess of Meloku the Clouded Mirror into an engine of escalating wealth by leveraging the unique copy and legend-ignoring abilities of Sakashima of a Thousand Faces. With Minn, Wily Illusionist watching over your illusions, sacrificing them to High Market triggers devastating cheat-from-hand effects that drop your lands back onto the battlefield. This constant cycling of your real estate directly fuels Three Tree City, allowing its massive mana production to pay for Meloku's activations and keep the entire assembly line running indefinitely.
