Djinn of Rituals, known as " Ritual Genie" ( 儀 （ ぎ ） 式 （ しき ） 魔 （ ま ） 人 （ じん ） Gishiki Majin) in the Japanese version, is a series of DARK Fiend- Type monsters released in the Booster Packs and Stardust Overdrive , and gained another member on Absolute Powerforce . They each share the effect text "When you Duelist Alliance Ritual Summon a Ritual Monster, you can banish this card from your Graveyard as one of the monsters required for the Ritual Summon.", followed by their individual effects, which are given to the Ritual Monster they were used to Summon. The purpose of these Monsters is to make Ritual Summoning more viable.
Visually, all Djinn of Rituals monsters resemble strange, obese humanoids wielding weapons or magical tools. Their bodies are usually one single predominant color. Every Djinn has a skull somewhere on their weapon and each Djinn has a different
Level and effect, having a dynamic engine to summon and boost Ritual Monsters:
Djinn of Rituals skull place Level Additional Effect
Releaser the middle of the Staff 3 while the Ritual Monster is face-up your opponent cannot Special Summon
Presider the hilt of its Sword 4 draw 1 card when the Ritual Monster destroys a monster by battle
Cursenchanter on the orb on its Magical Staff 4 while the Ritual Monster is face-up negate the effects of Synchro Monsters
Prognosticator over the orb on its Flail 3 your opponent discards 1 card when they take battle damage from the Ritual Monster
Disserere middle of its Shield 1 Ritual Monster not affected by Trap Cards
Demolisher middle of its Axe 3 the Ritual Monster can't be targeted by your opponent's card effects
Ritual Spell Cards that Ritual Summon a specified monster (for example, " Black Illusion Ritual") don't require you to use the exact Levels for the Ritual Summon. However, you can not banish extra "Djinn" Monster Cards beyond those which would be sufficient for any given Ritual Summon.
As was mentioned above, the Djinn of Rituals are DARK monsters. Thus, they are compatible with " Veil of Darkness", " Allure of Darkness", " Escape from the Dark Dimension", " Armageddon Knight", and " Dark Grepher".
The last 2 can make setting up a Ritual Summon insanely quick. By summoning "Armageddon Knight" and then having him drop a Djinn, you're instantly set up for just about any Ritual Monster you like.
The Djinn also have decent ATK/DEF scores in their own right, so don't be afraid to simply Summon them. Plus, even if they are destroyed, you can still use them for Ritual Summons.
Remember, the Ritual Spell Cards: " Earth Chant", " Contract with the Abyss", " End of the World" and " Dawn of the Herald" all require you to use monsters that equal the EXACT Levels as the Ritual Monster.
Use " Burial from a Different Dimension" and/or " Doomsday Horror" to return Djinns to your Graveyard and use them again.
Use " Tour Guide From the Underworld" to Special Summon a Level 3 Djinn from your Deck. You can also use them to special summon a Rank 3 Xyz Monster such as " Number 17: Leviathan Dragon" and use its effect to put a Djinn into the graveyard.
You can use " Oracle of the Herald" and all of the Djinn of Rituals to Ritual Summon an almost indestructible " Herald of Ultimateness" .
