Vizzerdrix

I have a Vizzerdrix but the set/image(s) available to on the site doesn't match at all. Did some research and this version predates Sixth Edition due to it not having a set symbol but it has the same image, artist, and flavor text as the starter 1999 set. Can't find any information on Vizzerdrix to see which set it came from though.

Thanks,
