Isn't black rose playing cards already a name for another deck?
You're right, I seem to recall that there is another deck called black Rose. It was funded on indigogo I think.
It doesn't have artichokes for pips or courts decked out in Flash Gordon style costumes as I recall. This one does, maybe a good thing, maybe a bad thing. I kind of like it haha. Flash! Ah ah, he saved everyone of us. ...with artichokes.
