I'm not technically a new Tamagotchi owner but I figured out that this is the best place to ask this question. So, basically, I have been browsing though eBay a lot for older versions of Tamagotchis lately and I came across descriptions like "RARE BLUE CARDED" or "RARE RED CARDED". I have never came across these terms before and it would be great if anyone could tell me whether these 'Gotchis are really rare, or somebody just put this in the description to attract customers .
