@kryptonnn I have a couple of those gold-bordered cards but I don’t know much about them. I would guess as you’ve assumed that these fall between the original TopSun VS set and the GBA set, but as for when, where or how I do not know.
The Buizel card looks like a generic ‘Zukan Card’ which was what the “Adventure Card” series turned into (www.elitefourum.com/t/japanese-adventure-cards/21934/1).
