"Number 39: Utopia", known as "Numbers 39: King of Wishes, Hope" (Ｎｏ．（ナンバーズ）３９ 希（き）望（ぼう）皇（おう）ホープ Nanbāzu Sanjūkyū Kibō'ō Hōpu) in Japan, is an anime-only sub-archetype of the "Number", "Utopia" and "Utopic" archetypes. The cards in this archetype are used by Yuma Tsukumo and Astral as their signature cards. This archetype is solely supported by the anime effect of "ZW - Sylphid Wing". The archetype's counterpart in the TCG/OCG is, for all intents and purposes, "Utopia". The only difference between the two is "Number 39: Utopia Beyond", which belongs to the "Utopia" archetype but not this one.
