"Number 39: Utopia", known as "Numbers 39: King of Wishes, Hope" (No.39 希望皇ホープ Nanbāzu Sanjūkyū Kibō'ō Hōpu) in Japan, is a sub-archetype to the "Number", "Utopia" and "Hope" archetypes. They are used by Yuma Tsukumo and Astral as their signature cards in the anime and manga. They are supported by cards in the "ZW -" archetype. This archetype is equivalent to the "Number C39: Utopia Ray" archetype.
This archetype is solely supported by "ZW - Sylphid Wing", as it has the clause "You can target 1 "Number 39: Utopia" monster you control" (「「No.39 希望皇ホープ」と名のつくモンスター1体に装備する事ができる。」).
