Harpie

The Harpies is a special group of monsters identified by having "Harpie" 「ハーピィ」 in their Japanese name and the phrase This card's name is treated as "Harpie Lady" in their text with the exception of the original Harpie Lady. All Harpie Monsters are Wind-Attribute, Winged Beast-Type monsters.

However, because of a ruling on the above-mentioned phrase, a player can only have three of any combination of the existing Harpie monsters (except for Harpie Lady Sisters and Harpie Queen) in their deck and side deck. In addition, Harpie's Brother is not a Harpie, since his Japanese name is 「バードマン」 or Birdman.)
