That's what I've been chasing lately. I'm currently at 76 unique Votto rookie cards and the ones that are missing from my collection either haven't been seen in months, sometimes years, or they're so overpriced on eBay that I'm not even going to attempt to make an offer. Hopefully I can snag some more unicorns before the end of the year but prices for Votto rookies have skyrocketed ever since he passed the 300 home run mark earlier this season. As for rainbows, I've been working on putting together a fun little collection of Votto refractors for my collection. I'm looking at trying to acquire 90 different Votto numbered parallels. So far the majority of my refractors are of the gold variety so I guess you could say there is a pot of gold at the end of this rainbow. I do have an orange, a green and a couple of blues. If your interested in seeing what cards I've acquired you can hit the Votto Parallel Universe Project link in the navigation.
