How ranking works

Balanced: 0.60*text + 0.20*tags + 0.10*color + 0.10*cost. Outputs are unitless rankings, not percentages or probabilities. Most similar shows the highest scores; Typical overlap is nearest the catalog median (0.524); Least similar shows the lowest scores.

Text uses cosine resemblance (−1 to 1) between 384-number embeddings when available, or lexical fallback otherwise. Tags use Jaccard overlap of approved tags and AI themes, excluding predicted tags and separately scored color/cost tags. Color compares W/U/B/R/G identity. Mana cost combines mana-value proximity, 1 / (1 + the difference), with mana-symbol overlap. Tags, color, and cost range from 0 to 1.

Model: bge-small-en-v1.5. 34,605 of 34,605 catalog cards currently have embeddings.

Potential synergies

No matching candidates found.

1,031 of 34,605 canonical cards have AI-derived resource labels. Label model: gpt-5.6-luna.

These suggestions use AI-derived resource labels, which may be incomplete or outdated. They are not rules-validated interactions.

This card has resource labels, but no synergy matches were found.

How these suggestions work

Synergy candidates compare resources Behind the Mask is labeled as providing with candidate payoffs, and candidate resources with Behind the Mask's payoffs. Candidates are excluded when either card is labeled as hating a resource the other provides or has a payoff for.

Each distinct resource and direction counts once. Highest counts rank first, with ties ordered by card slug. No deck legality or color filter is applied. Check costs, timing, restrictions, and the cards themselves; these are not probabilities or guaranteed counters.
