"'''Harpie'''" (ハーピィ ''Hāpyi'') is an [[archetype]] of [[List of female cards|female]] [[Winged Beast]]-[[Type]] [[Monster Card|monsters]]. "[[Harpie's Brother]]" is not a Harpie, since his Japanese name is "Birdman" (バードマン ''Bādoman'').
==Maximum of 3 Rule==
Harpie Ladies usually have the phrase ''This card's name is treated as "Harpie Lady"'' in their effect text. Their name is also treated as "[[Harpie Lady]]" while in the player's [[Main Deck|Deck]]; a player can only have a combination of 3 cards whose name is treated as "Harpie Lady" in their Deck. "[[Harpie Queen]]" is the only exception to this rule, since its effect only has her name treated as "Harpie Lady" while she is on the [[Playing Field|field]] and in the [[Graveyard]]. However this also mean that she is the only "Harpie Lady" that can't be searched by "[[Birdface]]" or "[[Elegant Egotist]]".
"Harpie Ladies" "[[Harpie Lady 1|1]]", "[[Harpie Lady 2|2]]", and "[[Harpie Lady 3|3]]", as well as "[[Cyber Harpie|Cyber]]" are treated as if their name is "Harpie Lady" at all times for all rules of the game, including in the Deck, hand and Side Deck.
