Went through the images (base set) on COMC, TCDB, etc, and the picture above. I haven't found more than 3 variations for any of them at this point. I have confirmed 3 variations for 18 of the 50 cards and 2 variations for 15 more, leaving 17 with only one variation confirmed. My SAGE Hit cards are buried right now, but I'll try to dig them out. As a team collector I only have a few players, but maybe I'll be able to add to the list. If anyone else can add any to the list, let me know and we'll see if we can't bang out a complete checklist.
Here's what I have so far...
