RichardWow that's a tough one.
If you're dead set on a single card, I'd probably sit down and make two lists.
The first list would be of the players that are worthy (based on my opinion) of being the only card in my collection.
The second list would be of the various issues that would be worthy (again, my opinion) of being the only card in my collection.
Then I'd try to find a match on that list that works for me and fits in my budget.
Regards,
Richard.
NB. For the record, I've actually tried this a couple of times hoping to create the wantlist for a 10-card collection. I have yet to be able to narrow it down to less than 25
