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 (0.144); 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. 0 of 34,605 catalog cards currently have embeddings.
