This card's name becomes "Harpie Lady" while on the field or in the GY. If this card is Normal or Special Summoned: You can add 1 Spell/Trap from your Deck to your hand that specifically lists the card "Harpie Lady Sisters" in its text. If you controlled a Level 5 or higher "Harpie" monster when you activated this effect, you can also add a second such card, with a different name from the first. You can only use this effect of "Harpie Perfumer" once per turn.
Some people are too young to know what makes a good card. Just to inform you, Stratos was the first monster that had a free search effect that provided an instant +1. And was in the TCG limited list for this reason for A LONG time. DL has not reached the TCG power level of that era. Despite that, stratos is free.
