Jim,
If you're interested in Challenge the Yankees, I encourage you to check out
www.challengetheyankees.co. The creator of CTY is preparing an Indiegogo campaign to relaunch the game in its original form. There's a box near the bottom of the page where you can subscribe to a mailing list and get a notification when the campaign begins. That's the best way to get your hands on CTY cards and complete games.
Best,
Michael Sokolow
Partner, Challenge the Yankees
