It is a conglomerate which carries out counselling and economic forecast, using magical and scientific prediction methods such as prophecy magic, clairvoyance and fortune-telling. It is involved in all kinds of business related to information, ranging from love divination and great scale divination of the fate of nations.
In order to counter industrial spies that try to steal their information, they pay efforts in training agents responsible for combat and security. With that know-how, it supports the nations from the rear, carrying out tasks like development of new armament for knightly orders and dispatching security guards and witch corps.
Oracle Think Tank's main focus is increasing the player's hand size in order to keep guarding the opponent's assaults until they run out of resources. They also manipulate the deck to some extent to have more control over which cards they draw and know when they'll Drive Check Triggers. Their keyword is Oracle, which activates when the player has 5 or more cards in hand.
Oracle Think Tank relies less on brute force than other clans. Instead, they apply pressure by Drive Checking more triggers and restricting the opponent from guarding with Grade 0 cards.
Tsukuyomi relies on checking the top five cards of the Deck then returning them to the bottom in any order, by doing this enough times and never shuffling, the player can eventually stack the entire deck.
The Witches focus on having one or less cards in the soul.
The Magus focus on guessing what's the top card of the deck, which they do by looking at it beforehand.
The Battle Sisters draw power from their rear-guards and use a large amount of on-hit effects.
Susanoo looks at the top two cards of the deck and decides which to add to their hand and send the other to the bottom of the deck to improve the quality of their draws.
Most of the units are based on the deities and mythical creatures from Japan with some from Greece (e.g. Euryale, one of the three Gorgon sisters; Sphinx, the riddling guardian of the Greek city, Thebes; Apollo, the Greek god of the light and the arts; and Nike, the Winged Goddess of Victory; etc.).
