This was a rather difficult one, as Yugioh has many dark damsels to choose from.
In the end, I arrived at Fortune Lady Dark — https://yugipedia.com/wiki/Fortune_Lady_Dark —, for a @shadylady that twists one's fate seems to fit fairly well.
And, of course, Shadow Spell — https://yugipedia.com/wiki/Shadow_Spell — is a real card, which represents her ability to ensnare others while remaining hidden herself.
Naturally, she wouldn't be a shady dealer if she didn't ask for something in return.
