Indeed, though open-ended, this would still be a misleading description if it ends up a Normal-type! Now, just what could it end up being. I think the colouring shuts out possibilities for currently known types (except for Poison... LOL
). If not Normal-type, which would be disappointing on itself, there's no way this does not introduce a new type. Of course a new type can end up disappointing on itself... Can you imagine Fairy-type? I don't know what I would think of this.
