Sartorius' Decks

Society of Light
Sartorius uses a Tarot Deck which is composed of "Arcana Force" monsters based off the Major Arcana, with Spells and Traps based on the Minor Arcana to complement his monsters. His cards have the unique ability to appear in either upright (normal) or reversed (upside-down) positions, which dictates their effects. When activated, Sartorius' cards rotate and it is up to the opponent to decide when to end the rotation, in turn deciding his/her own fate. (In the TCG/OCG, this "position" is represented by a coin toss.) The design of cards in the "Arcana Force" series has links to the Cthulhu Mythos. In the Japanese version the names of the "Arcana Force" monsters are separated by underscores instead of hyphens.

Darkness
In the Darkness arc, Sartorius utilizes a new Lockdown/Mill strategy which reflects his changed philosophy on destiny revolving around the combination of "Arcana Force 0 - The Fool", "Tour of Doom", and "Sowing of the Fool". By slipping "The Fool" into Jaden's Deck, it enables Sartorius to choose which effects of any other "Arcana Force" monsters activate without relying on chance. Through this he can safely use the effect of "Tour of Doom", which has an equal chance of preventing either player from Summoning a monster during their turn, to shut out his opponent's ability to Summon monsters entirely. In addition, "Sowing of the Fool" gives Sartorius the ability to discard cards from his opponent's Deck. The use of "The Fool" in his rematch with Jaden is significant because during the Society of Light arc, Jaden's actions in Sartorius' predictions are determined by the Major Arcana card called "The Fool".
