Hmm, but that will filter out more than half the players on the Match Wins and Trophies based leaderboards, many of them Diamond and Mythic. So I think your choice of 62% match win rate is almost certainly disproportionately selecting for people who received very good draft choices, even if it includes some actually very good players in the data set.

I mean 62% might feel like a good number, but it's arbitrary, you'd have to justify how you chose it, and just eyeballing it, it is filtering out a lot of very good players with many, many more match wins.

Perhaps you can sort by Latest Rank, and filter out people with 2 or fewer trophies. Or you will have to validate with known bad draft choices in the prompt, to see what it does. Suffice it to say, I still don't think the 17Lands data represents what you think it does.

Like without a direct discussion about measuring and accounting for luck in the draft... for all I know the data is seriously flawed. It probably isn't, but it's maybe one of many, many issues to address when dealing with strategy card game AI problems.
