Activate Meloku by paying 1 and returning the land from the battlefield to your hand, creating a 1/1 Illusion creature token.
Activate Grafted Wargear's equip ability by paying 0, attaching it to a different Illusion.
Grafted Wargear triggers, causing you to sacrifice the Illusion it was initially attached to.
When the Illusion dies, Minn's second ability triggers, putting a land from your hand onto the battlefield.
Repeat.
This ingenious loop turns a simple self-contained engine into a permanent-cheating machine by letting Grafted Wargear continuously assassinate its own carriers. By using Meloku the Clouded Mirror to bounce lands for tokens and fuel your hand, you create a steady stream of Illusion fodder. Equipping Grafted Wargear for free to a new target forces the sacrifice of the old one, which triggers Minn, Wily Illusionist to drop powerful permanents directly onto the battlefield.
