Panini seems to be cranking out it's upper end stuff lately. Pantheon also looks incredibly similar to Prime Cuts and Immaculate. And like every high end Panini product I've seen in the past few years the numbering in the official checklist will be wrong. Most of the inserts will be labeled with lettering not numbers. So with this checklist as cards start to show up and I can confirm the correct card labeling I'll change it here and on the running checklist page. According to the checklist Robin has 26 cards in 7 different insert sets to chase and most parallels are pretty rare.
