Do not summon this card when only one "Harpie Lady" is on the field. If only one Harpie is on the field, use "Elegant Egotist" to Special Summon another before Normal Summoning this card.
When used in conjunction with "Harpie Lady 1" cards, this card becomes extremely powerful rapidly, and its effect to destroy one card per turn is invaluable, making it both easier to summon and more powerful than "Harpie's Pet Dragon".
You can Special Summon this card straight from your Deck by the effect of "Harpie Channeler". This has the added benefit of making sure it has at least 1 Harpie monster in play for its effect.
You can search this card from your Deck to your hand with the second effect of "Hysteric Sign", along with 2 other Harpie monsters. This can make getting its effects active much easier.
Use this cards effect while you have at least 3 "Harpies" on the field to destroy a card, then return it to your hand and Normal Summon it with the effect of "Harpie Dancer", this allows you to use the effect a second time effectively letting you destroy 2 cards per turn for free.
