GEMP Card Analytics

Understanding the Statistics

Games
Number of games where this card appeared in at least one player's deck.
Inclusion WR
Win rate when the card is in your deck, whether played or not. This is often a statement about that deck rather than that card.
Players
Unique players who included this card (helps identify "pet decks" vs meta trends).
Played
Number of times this card was actually played (not just sitting in deck).
Play WR
Win rate specifically when this card was played.
Priority
Games × (WinRate - 0.5). Combines popularity with impact. High priority cards are both common and influential. Low priority cards lose a lot proportional to their inclusion.

Known Data Issues

⚠️ Attached Zone Bug

Before January 2026, cards which played into the ATTACHED zone (such as weapons or conditions like Last Alliance) were incorrectly tracked and so never registered as "played". These cards will thus show as 0 played across the board. If you see a very low play stat and it is an attachment, disregard the Play WR for that card. Events are still affected by this bug and never show as played; this will be fixed in the future.

Other Considerations

Tips for Analysis

💡 Pro Tip: When analyzing a specific card, check both Inclusion WR and Play WR. If Inclusion WR is high but Play WR is low, the card might be good to have in deck but situational to play. If both are high, it's consistently impactful.
