Thanks, Brian -- it's weird. I didn't have any great affinity towards that set (E91). I just started picking them up. Many were really cheap at the time. Before I knew it, I had 20 or so, so I just kept going.

I really began to enjoy it because of the challenge. And while there aren't really cards in it that I consider tougher than the others (other than the fact that they seem to get slightly more plentiful with each progressive series), I'd argue that the entire series is just flat out difficult. You're certainly right in that there isn't anything stupidly rare. But at the National this weekend, I saw very few in total. Like a couple dozen.
