I’ve had a real struggle to find any information on these two cards. I would really like to know how they were given out (or awarded?) and how many of them were made. Any help would be appreciated! 
also, I know they came in a folder. If anyone has that folder, I’d be very interested in buying
Huh well that’s interesting. I just recently found out the japanese lottery versions exist lol. I searched the web a little and couldn’t find anything except your ebay and a video by a kid called pokecentral on youtube. Looks like he had the korean and japanese set. Might be worth a try asking him, although that video was like 2 years old.
I wish there was a bulbapedia page for them 
lol
But that would be too convenient
Rayquaza is on ebay. I believe the Rayquaza is #145 it is a promo. I think there were only 1000 given out or something like that.

Edit: Sorry just realized you meant the Korean version.
