I recently added more of the rarer slot card doubles along with more Montana and foreign slot card doubles on my website. Check each of the pages and let me know if you see anything you need. I still have a lot more rarer slot cards coming and I'm sure there will be many more additions over the coming months.

Here's a link to the rarer doubles on my website and you can navigate to the other pages using the buttons at the left
