I own this card and cannot find any other all-time teammate in a color set.

I've searched the forums for information and found none. Is this simply a stand-alone, or not even a legitimate TCMA product, let alone part of a set?
There's this other one (that I do not have) but is being sold as part of a color set (no other O's in that one, either), but I suspect it's nothing more than a cut-n-paste job from the Black-and-White set.

Any help on the first one?
