Alright, so here's a spreadsheet with the data. The hitting and pitching cards are on the first page and should be pretty straightforward, and if there are multiple criteria for a roll, you go top to bottom. The second tab has the Stats to Ranking method, so I recommend visiting Baseball Reference and Fangraphs to determine the stats for the players.
Basically, the dice rolls will allow a .300 hitter to hit that when the Batting Card is rolled, a HR heavy hitter will hit more, and they'll take walks and strike out at a general rate to what they did in reality. The master card is very limited and you'll find results are far more accurate and realistic using the actual cards, but I think this is an effective quick-and-dirty method for simming pick-up games like I do. Some of the data is old and a bit questionable (the K rating tops out at 9.6, which has been blown by, you can tell I set this up back in 2015-16).
