Due to their Japanese names containing 魔導, a number of older cards, such as "Armor Exe" ("Magical Armor Exe") and "Dark Paladin" ("Super-Magical Swordsman - Black Paladin"), also fall into this archetype. Even some cards released after "Stoic of Prophecy", such as "Ebon Illusion Magician", that fall into this archetype do not include "Prophecy" in their English names. However, because TCG and OCG support for this archetype only works on Level 3 Monster Cards in the Main Deck, none receive support and lack synergy with the Deck.
Each Prophecy Monster is based on a Tarot card of the Major Arcana. The English names come from the Rider-Waite tarot deck which uses the names "The High Priestess" and "The Hierophant" instead of "The Popess" and "The Pope" which is found in other decks. The Japanese names of the Prophecy monsters make reference to French-language tarot decks.
The Japanese title of "Fool", 魔導化士 (Madōkeshi), derives from the archetype name 魔導 and the word 道化師 (dōkeshi "clown; jester; fool"; the suffix 師 was replaced with the synonymous 士). All other non-Xyz "Prophecy" monsters then have their titles modeled after his by replacing 化士 (keshi) with other words, such as 剣士 (kenshi "swordsman") for "Chariot", 戦士 (senshi "warrior") for "Strength", 天士 (from 天使 (tenshi "angel")) for "World", etc. The title of "Spellbook Magician", 魔導書士 (Madōshoshi), also neatly contains 魔導書 (Madōsho "Spellbook").
Several "Prophecy" monsters also share the same ATK/DEF values as several of Yugi Muto's signature monsters.
A loop is possible using "High Priestess of Prophecy" that can ensure the monster gains 1000 ATK every turn, provided that she destroys a monster. You also need "Spellbook of Power" and "Spellbook of Eternity". Have "High Priestess of Prophecy" on the field, then play "Spellbook of Power". When it is in the Graveyard, use "High Priestess of Prophecy" to banish the Spellbook then attack to destroy a monster. The effect of "Spellbook of Power" activates and you can search for "Spellbook of Eternity". Next turn you can use "Spellbook of Eternity" to add "Spellbook of Power" to your hand. This loop can be prolonged by using "The Grand Spellbook Tower" to return "Spellbook of Eternity" to your Deck. If you need to dump Spellbook cards into your grave for whatever reason this can be possible by searching for "Spellbook of Secrets" instead of "Spellbook of Power". Then you can use "Spellbook of Secrets" to search for "Spellbook or Power" to continue the loop or a separate "Spellbook" card if needed.
This loop is easily broken if you cannot destroy a card with the effect of "High Priestess of Prophecy" or cannot destroy a monster by battle. However if this is your situation you may use the same technique to reuse "Spellbook" cards by banishing needed cards instead, then adding them to your hand via "Spellbook of Eternity".
Used in conjunction with "Spell Absorption" this loop can potentially be an extra 1000 life points every turn and an extra card in every standby phase.
Another way to recycle Spellbook of Power is with "The Grand Spellbook Tower" and "Spellbook of Secrets". Play "Spellbook of Power", use it to search for "Spellbook of Secrets". Then use "The Grand Spellbook Tower" to put "Spellbook of Power" back into the deck.
You can also perform a mini-loop using "Strength of Prophecy", by summoning it, and using Spellbook of Power to bring Strength to 2500 attack. Next you can use Strength's effect to recycle Power from the grave to bring itself to 3000 attack. Then attack a monster and destroy it to add a Spellbook of Secrets from the deck via Spellbook of Power.
The "Prophecy" archetype is overall so diverse in terms of monster stats (minus their Type) and strategies that it's almost impossible if at all to completely render this Deck moot as well-built "Prophecy" Decks can be very resilient and multi-faceted in terms of play strategies. However, there are some cards that can deter these kind of Decks:
"Spell Canceller", "Cursed Seal of the Forbidden Spell", "Morphing Jar 2" and/or "Eradicator Epidemic Virus" - Can deadlock "Spellbook" Spells from being played, however the first may also lock your own Deck. The second could be a temporary reprieve if you run a good amount of Spells, but may backlash against you if your opponent gets monsters out, which well-built "Prophecy" Decks will have a diverse way of doing so. The third may often rely on chance, yet if your opponent lacks monsters in their Deck or better yet have used most of them along with having a lot of them on the Field, it could severely Deck your opponent out. The last card does not stay on the Field and forces your opponent to reveal every card they draw for a few turns, but not every Deck will be able to use it either at all or very easily, given its pre-effect Cost.
"Spell Shattering Arrow" - While more staple S/T removal (i.e. "Mystical Space Typhoon") can also be temporary alleviators against "Prophecy" Decks too, this card in particular can be harshly judgmental by not only wiping Spell Cardsen masse at no cost to the user, but also inflicting hefty damage as well.
A more efficient way to temporarily relive their Field presence is "Last Day of Witch", which can serve as a "Raigeki"-esque turnaround against "Prophecy" monsters, so long as you don't run too many Spellcasters yourself, if any at all.
"Nanobreaker", "Armed Dragon LV5", "Armed Dragon LV7" and/or "Shreddder" - Can clear the opponent's field of the lower-level "Prophecy" monsters, especially those that could have game-changing effects. Like the directly above noted cards though, cards like "High Priestess of Prophecy" and "Hierophant of Prophecy" can hastily end this opposition.
"Droll & Lock Bird", "Prohibition" and/or "Psi-Blocker" - Can stop many Spellbook-theme cards: "Spellbook of Judgment", "Spellbook Library of the Heliosphere", "Spellbook Star Hall", "Spellbook of Power", "Spellbook of Secrets", and "The Grand Spellbook Tower" as well as key "Prophecy" monsters from being used. Again though, these "one-card armies" can be easily put down, especially in the current meta, which has focused more on Field control.
"Deck Lockdown" and/or "Mistake" plus/minus "Thunder King Rai-Oh" - "Prophecy" Decks often times substantially rely on Toolbox tactics to add "Prophecy" monsters and "Spellbook" Spells from the Deck to the Hand to keep Hand resources and play options motley. That being said, these cards can extensively make Hand advantage much more sluggish by making Toolbox card effects useless.
"Puppet Plant" - This card can flich a high-powered "Prophecy" monster in a pinch; it's not as easy to interdict unless it is discarded beforehand or if "Mind Drain" is used. Better yet, the monster can afterwards be either Tributed, used for an effect or even as Synchro or Xyz Material (i.e. with Xyz Summons, use two of this card to embezzle two "High Priestess of Prophecy"s and then Xyz Summon "Number 11: Big Eye" (in the TCG) or "Mecha Phantom Beast Dracossack").
