Forum:Harpie queen

Hey I am just gonna ask about something referring to the harpie queen card. We are all aware of her special effect; if not see this http://yugioh.wikia.com/wiki/Harpie_Queen

Her ability clearly states that she is counted as a harpie lady on the field and in the graveyard.

Here is my question, if there are three harpie lady in the graveyard already and what if the Harpie queen goes to the graveyard as well. Does the Harpie queen goes to the graveyard? send out of the game? or she stays on the field and the damage is calculated normally?

Thank you for your time!
