"Blue carded"? "Red carded"?

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 .

You mean like this?

I think it's referring to the color of the "card" in the Tamagotchi's packaging.

"Rare" is just part of the normal description I think, and a lot of people use "rare" in Tamagotchi descriptions on eBay when they really aren't.

Yeah, that's exactly what I meant! Actually, the Tama you linked is from the seller who I bought my P2 from . Thanks.
