The Darklit Planets pin set is widely considered to be the most powerful deck one can obtain in The World Ends with You. Other than via a mingle shop, the pins can only be obtained after the game has been completed, and each pin must normally be won off from certain Noise on Ultimate difficulty. WildKat will have one of the pins for sale, which is determined by the DS unit. Each pin may be used by itself, but when all of the pins in the planet set are in the same deck, psych efficiency is tripled. When using the deck, four of the six pins are commonly used.
