Ideally I'd like this to be Ascension 20 only, but I'm trying to get as large of a sample size as I can to increase the accuracy of the tier list and Ascension 17 is a reasonably close cutoff in terms of difficulty. Otherwise scores would inflate for cards that perform well late in the game. Act 1 scores are weighted higher and Act 3 scores lower to compensate for higher spread of winrates later on.

Some cards don't have data on when they were obtained (transform and copy events, the Library, etc) plus cards obtained at the start from Neow's bonus are labeled as "Act 0" and not shown in the simplified table, but included in the overall score (and you can see their stats on the detailed tierlist table). Why don't scores for all acts add up to the total?

Lastly, Act 1 scores are weighted higher (1.5) and Act 3 scores lower (0.5) to compensate for higher spread of winrates later on. So I just capped it at losing 50 points and set that as 0, since beyond this point the card can just be safely labeled as "bad" and dismissed.

I considered throttling low-sample negative scores the same way, but linear scaling wasn't doing the trick and cards still ended up with -300 when they have 0 winrate out of 7 samples in Act 3 or something like that (and it would take forever to get more samples, since nobody picks the card in the first place). Negative scores are not throttled, but hard-capped at 0 instead. For cards that are picked more often the system gains more confidence in its evaluation and this penalty decreases linearly until it disappears completely for cards in the 40th percentile of popularity and above. Positive scores are "throttled" for cards with low sample size, meaning cards that are rarely picked get only a small boost to their score, otherwise you'd have stuff like Flechettes unreasonably high because the card actually does well when picked in exactly the right deck, but 99% of the time nobody takes it since it's generally really bad.

They are derived from winrates of each card compared to the average winrate of all cards, broken down by act - you can see the actual winrates and more info in the detailed tierlist table.Īt the basic level, it's just delta winrate*1000 (to make a nice round number) and then act scores are added up together, but there are some adjustments: It costs 0 until played.įilter: Common Uncommon Rare | Low Frequency Card Place a card (any number of cards) from your hand on the bottom of your draw pile.
