User:Chadook/List of unplayed cards
This page lists cards that have been seen in all Yu-Gi-Oh! media, but have not been used, or briefly seen for demonstration purposes. These cards have not been shown in full details, or used their effect, or just appeared to be some sort of fodder.
Zane's Cyber cards
Syrus's "Roid" Normal Monsrers
"Alice in Despairland"
- This card only appears at the end of the episode 79 during the copyright section (after the 'next episode' preview). The scene shows Bastion Misawa in his room resarching information about Alice, and finds the profile of this mysterious card, he is then attacked by the spirit monster of this card. As the scene ended up being removed from the episode 80, aside from it being an Effect Monster nothing is known about it, it did not appear in the actual episode, nor printed in the TCG/OCG. 
"V Sylph", "V Undine" and "V Gnome"
- 5 cards of the "V" cards were given to Yuma Tsukumo by Ray Shadows to support "Number C39: Utopia Ray V". Only "V Salamander" was used, and only "V Salamander" and "V Call" were fully releaved. The rest of the archetype cards, besides from them being Level 4 Spellcaster monsters with various Attributes and Stats, "V Sylph", "V Undine" and "V Gnome" never appeared in the anime outside their card forms, or had their effects (if any) shown.
