What the fuck was the point of the ??? type? Literally what fucking purpose did it serve? You already had Normal perfectly capable of being a placeholder type and Typeless is already a property in the game that was introduced IN THE SAME FUCKING GENERATION AS ??? TYPE so it doesn't even have the excuse of being a carry over.
What does Curse really need to be it's own special type because, well I don't fucking know and clearly GF saw it as a mistake as they changed the type to Ghost which then raises the question once more, WHAT THE FUCK WAS THE POINT OF ??? TYPE?
