I'm working on a harpie deck and I think someone already posted this but can you have 3 Harpie Ladies,3 Harpie lady 1,3 Harpie lady 2,3 Harpie lady 3,and 3 Cyber Harpies?

No, you cannot have 3 Harpie Lady, 3 Harpie Lady 1, 3 Harpie Lady 2, 3 Harpie Lady 3 and 3 Cyber Harpie in your deck, because their effect states that they all count as Harpie Lady, and you can only have 3 of any card in your deck.

Because of the fact they all count as "Harpie Lady", this restricts them to follow the 3 card per deck rule meaning you can only use a combonation of 3 "Harpie Lady", "Harpie Lady 1", "Harpie Lady 2", "Harpie Lady 3", and "Cyber Harpie".

The ruling may help you understand it a bit better.

This also includes Cyber Harpie since Cyber Harpie is treated as Harpie Lady.

See. Hapries are like gravekeepers. There are alot of them and are very versatile. The only difference is we can only use three of them. It's sad, in my opinion. You can try to make a Harpie deck, but you'll probably find yourself creating a winged-beast deck in the end.

But to make this relavant to the thread, you can include three Harpie Lady Sisters in addition to 3 Harpie cards, so they are excluded from that restriction.

well if you want a harpie deck try this. i built one for my gf since she liked the harpie lady. it had harpie lady 1, harpie lady 2, harpie lady 3 (although one's effect is pretty crap so i would replace her with a cyber harpie) 3 elegant egotist, 3 harpie lady sisters, 3 triangle ecstacy spark, 3 harpie chick, 3 harpie brother, 1 harpie's pet dragon (as it's so hella hard to get, you might wanna try to leave him out) 3 birdman (to get harpie ladies) 2 garuda the wind spirit, 2 harpie's hunting ground. then just throw in some staple magic/traps like CotH, Premature Burial, Heavy Storm, MST, Dust Tornado, or whatever you feel helps you better. hope that helps you alittle
