Now that I see the grey text Ninetales on the previous page, it reminds me of a similar more commonly found error on Team Rocket Holofoil Rares that isn’t included in the list yet: www.elitefourum.com/t/are-theses-cards-missprint/24848/1
The solid black layer they apply during the printing process after the KCYM layer is basically missing.
