I think that they‘re not misprints, Konami did that on purpose. I mean PP02 has also Supers as Secrets. I don‘t think they would mess it up twice in a row. PS: I found 3 Zera in Secret Rare on Cardmarket for 10,99€ 😄
dickvieh that’s very true...! I was going to mention that PP02 has the same mistake!? Or maybe it was intentional by Konami! I guess we will never know!
