There's 4 total, outlined on Greg's page!
yep, there are four card duplicates on the uncut sheet.
I brought this up about three years ago with Greg, and provided scans of the card fronts for all 8 cards.
The Eviltime is the only one that may not be immedialtely obvious, as they both have a checklist backing, but the image on the front is noticeably different between the two.
The reason is that all four of the duplicate cards used images of die-cut stickers as their source. Resulting in the image of the die-cut being visible on the card. So all four cards have both an image of a die-cut and an actual die-cut. It doesn't look like Greg included this additional info that I provided to him though.
