Rick Porcello has a "Peak Performance" jersey card, and a blue parallel of that card numbered to 99 copies--seemingly similar to the "Career Best" and "Career Best Platinum" cards from 2009 Topps Series 2.
I think its safe to say that early returns for Tigers fans are good. My team set has been ordered ($1.25!) and I'm very excited to flesh this set out over the course of the week.
