Lazar's Decks

Anime
Lazar plays a "Jester" Court Deck, in which he uses monsters that resemble court jesters, and Trap Cards that limit the moves his opponent can make. Most of his Trap Cards are Continuous, which serves to limit the number of monsters Summoned to the field by his opponent while strengthening his key monster, "Jester Lord". Several of his cards reference a royal court of justice, which correspond to his career as a top officer of public security. His cards appear in the Ancient Prophecy booster pack. Most of the cards in his Deck seem to also belong to the Cup Ramen Man in his Duel Puzzles at the arcade machine. This is probable seeing Lazar's love of Cup Ramen.

Dark Signer
Lazar uses a "Jester" Lockdown Deck', focused around putting his opponents in a position where they are unable to Summon monsters, meaning "Jester Lord's" ATK will remain in high levels.

World Racing Grand Prix
Lazar continues to use a "Jester" Deck, with more support for his "Jester Lord" as well as his "Jester Queen".

Manga
In the manga, Lazar uses a "Jester Puppet" Deck, which centers around Ritual Summoning his ace monster, "Jester Puppet King Pantomime".
