You can Ritual Summon this card with any "Gishki" Ritual Spell Card. Once per turn: You can declare 1 Monster Type and Attribute; look at 1 random card in your opponent's hand, and if it is a monster of the declared Type and Attribute, shuffle it into the Deck. Otherwise, return it to the hand.
Allows you to declare Monster-type and Attribute and potentially shuffle that card from your opponent’s hand back to their deck.

By discarding Gishki Vanity you can potentially prevent your opponent from using cards like Curse of the Forbidden Seal and Floodgate Trap Hole that can disrupt your Ritual Summons.
The challenge of Ritual Summons for Gishki is that all the Ritual Spells require exact level of Tributes, for Gishki Pyschelone it is easier since it requires a level 4 monster as Tribute for Ritual summon.
Alternatively, you can also use Senju of the Thousand Hands to search for Gishki Ritual monsters from your Deck.
Gishki Aquamirror is currently the best Ritual Spell card for Gishki ritual monsters. It can recycle itself from the Graveyard to your Deck, at the same time you can also recycle 1 Ritual monster from the Graveyard back to your Hand as well. Forbidden Arts of the Gishki is a powerful Ritual Spell card to use your opponent’s monsters as tributes for your Ritual Summoning instead, but the drawback is your Ritual Monster’s ATK is halved and you cannot conduct Battle Phase during the same turn.
