This contains an interface to card winning stats that depend on having up to two other cards available in the supply. It also ranks cards and determines how much a cards quality changes as a function of having other cards available.

### Interpretting the stats

This let's you see how cards perform when others are available to be gained. When a card is conditioned upon, it simply restricts the statistics to games in which that card was available in the supply. The conditioned upon card does not ever have to be gained.

• Availability: The number of games in which the card is present, multiplied by the number of players in each game. It represents the number of "decks" that could have purchased that card.
• %+: Percentage of times the named card was gained at least once.
• Per Gain: This is win rate on the card on a per gain basis. If player 1 bought the card 5 times and won, and player 2 bought the card 3 times and lost, then this would count as 5 wins and 3 losses in two player games, giving a win rate of 5 * 2 / (5 + 3) = 10 / 8 = 1.25.
• Any Gain: This is a win rate that does not include multiple gains of a card in the same game. In the above 5 winning vs 3 losing example, the card would have a win rate of 1, because both players purchased it.
• Num Gained: The average number of the times the card was gained when it was available, per player.
• Quality: This is a measure of card quality that tries to recover the excellent community card rankings using only the statistics about the cards and information about the cards themselves. Currently the ranking function recovers almost 90% of the community ordered pairs, using only the following signals:
• the win rate given any gain
• the chance of a card being gained
• the number plus actions
• whether it has vp
• whether it's a reaction
• Δ Qual: The change in quality given the conditioned cards are available.

### Tips on using the card filters

List different card names or card filters separated by a comma. Each filter is a JavaScript expression that is matched against every card. The expression is evaluated with attributes of the card filled as local variables. If this sounds confusing, don't worry. Here are some examples:

• Expansion=="Dominion" || Expansion=="Intrigue"

• Cost==7 returns Bank, Expand, Forge, and King's Court
• Cost == "P2" returns Apothecary, Scrying Pool, and University
• (""+Cost).indexOf("P")>=0 returns all cards with Potion in cost

• Actions >= 2 returns all cards that provide 2 or more Actions
• Cards < 2 returns all cards that draw either 0 or 1 Card when played
• Coins == "?" returns Bank, Philosopher's Stone, Pirate Ship, Salvager, Secret Chamber, Trade Route, Tribute, and Vault
• VP >= 6 returns Province and Colony
• Trash == 4 returns Chapel

• Action && Victory returns Great Hall, Islands, and Nobles
• Treasure && Victory returns Harem

• Attack returns all Attack cards
• Duration returns all Duration cards
• Reaction returns all reaction cards
