Hi! Thank you so much for the help! I came across that guidebook too and got excited for a minute, but when I searched for Nintendo Power cards... nothing comes up for it :^( I came across an eBay and Mecari listing with my cards (the eBay seller had an Eevee) and none of the sellers knew where they got them. I'll attach the links here if you want to check them out!
