Sent in for 12, got the bonus pack like a few others have noted on various forums. Here are the hits, all of which have been listed on eBay under the same username I have here:
Auto (#/50): Drew Hutchison
Reds (#/25): Matthew West, Kyrell Hudson, Dante Bichette Jr. and Rafael Ortega,
Blue notables: Harper, Cole, Bradley Jr., Bogaerts
Already sold the remaining 56 base blue cards tonight.
These are such nice looking cards, hope they return again in a future set.
