thanks! That helps a lot, although I am not familiar with that area of knowledge.

Indeed, I got some ML metrics on a test split that gives me an idea of its accuracy :) But it's just an estimation, so indeed I am looking out for feedback to know its real performance so I can debug bad cases and fix those with more data or a better model.

The test performance on subreddit r/hearthstone is 0.21 f1-score, which is not great. And looking at the confusion matrix for r/hearthstone it gets often confused with:

r/BobsTavern r/CompetitiveHS r/customhearthstone r/Blizzard

If you are curious, I uploaded the metrics (precision, recall, f1-score) and confusion matrix on the test dataset on a Google Spreadsheet.
