CubeWizard turns submitted deck photos into card lists, then computes per-card and per-color performance from match records.

Data flow

• Upload: A user submits a deck photo + match record (W/L/D) for a selected cube.
• Processing: Uploaded data is run through an OCR (Optical Character Recognition) process to determine the list of cards included in each deck.
• Analytics: Processed decks are analyzed and findings are shown via this site.

Stored Information

• Record (W-L-D): The match record entered on submission.
• Win%: W / (W + L). If W + L = 0, Win% is treated as 0.
• Cards: The number of card names extracted from the image.
• Pilot: The user-provided name of the deck pilot.
• Uploaded: The timestamp when the deck was recorded.

Dashboard tiles

• Total Decks: Count of decks stored for the selected cube.
• Unique Cards: Count of distinct card names that appear in at least one stored deck for the cube.
• Average Win Rate: The mean deck Win% across all decks in the cube (each deck weighted equally).

Card performance

• Appearances (Apps): Number of decks in the cube that contain the card at least once.
• Card record (W-L): For each deck containing the card, add that deck’s wins to the card’s wins and that deck’s losses to the card’s losses.
• Card win rate: card_wins / (card_wins + card_losses).
  • Laplace smoothing with a weight of 5 is applied to each card’s win rate. In short, we assume that every card is played in 5 synthetic ‘decks’ that have a winrate equal to the cube average. This means in practice that cards start with a cube average winrate, and have to show a consistent above average performance to move their winrate substantially.
• Performance delta (Δ): card_win_rate − cube_average_win_rate.
• Popularity: Shown via appearances (and in the scatter, higher appearances means more-popular cards).

Synergies

• Together: Consider only decks that contain both cards in the pair.
• Together record (W-L): Sum deck W/L over decks containing both cards.
• Together win rate: together_wins / (together_wins + together_losses).
• Synergy bonus: together_win_rate − average(card1_win_rate_over_all_decks, card2_win_rate_over_all_decks).

Color data

• Deck is “a color”: If it contains at least one card with that color in its color identity.
• Color win rate: Computed over all decks that qualify for the color, using the same W/(W+L) aggregation approach.
• Deck presence: Percentage of cube decks that qualify for the color.

Notes & limitations

• Small samples: With few decks, card and synergy deltas can swing heavily. The dashboard shows a “Small dataset” banner under 30 decks.
• OCR misses: If a card isn’t extracted or cannot be found in Scryfall, it won’t contribute to per-card analytics.

Tools

• Search decks by pilot name — list every stored deck whose pilot name matches your search (across all cubes), in the same table style as deck data. Click a row to open that deck on the cube’s deck page.
