Ishizu Ishtar's Decks

Ishizu Ishtar has used the following Duel Monsters Decks in various media.

Anime/manga
Ishizu primarily plays EARTH Attribute Fairy-Type monsters which bear an Egyptian appearance. She is only seen dueling once. This is against Seto Kaiba who was running his Virus Deck.

To counter his strategy of sending large amounts of cards to her Graveyard, her Deck revolved around returning his cards to his Deck so that she could activate "Exchange of the Spirit" and cause him to deck out. In the past, Yami Marik mentioned that Ishizu even defeated Marik in the past with her Deck.

Forbidden Memories
In Yu-Gi-Oh! Forbidden Memories, Isis plays a Water Deck. Her strongest card, "B. Skull Dragon", is her only monster that is not WATER-related.

World Championship 2008
In "Yu-Gi-Oh! World Championship 2008", she uses a Deck called The Keepers, which focuses on the use of "Gravekeeper's" monsters, with the trump card "The End of Anubis" to completely lock down the opponent's Graveyard.
