Well what you're asking may happen. I mean CB goes for 50 dts, while it require 70+ dts to add stats so that you make 0/0/50/50/50 becoming 0/0/100/100|80. So that's actually a good deal
Have not seen one thats anything but all 0 on attributes so I would assume mines drop is either very hard to achieve or it doesnt drop at all.
Do you have a few pd?
If you have photon crystals then just do black paper deal 2. Its not hard mission and not a hard drop. If you have anything for trade then you can buy one from a player for a few pd tops.
