Cards enter a broader collection loop

The Steam description connects card discovery to rummaging through garbage and opening unopened cereal boxes. The GIGA patch adds another route: collect five card fragments and glue them into a complete card.

Once found, cards appear in a binder organized by four color tabs. The official trailer clearly shows blue, pale-gold/white, red, and purple spreads. Steam’s achievement wording supplies the public names for those sets.

Rarity, set, and stats are separate

  1. Set: blue, white, red, or purple; used for completion achievements.
  2. Rarity label: R, SR, or SSR, exactly as printed in the binder.
  3. Stats: HP and ATK values printed on the card.
  4. Card text: an effect or ability printed below the stats.
  5. Copy quality: an individual-card property that can affect selling value.

What the binder footage can and cannot prove

This database records 35 names that are legible in official public footage. It does not convert visible blank slots into fictional records or claim that 35 is the final shipped total. Your current in-game binder remains the authoritative completion view.

Keep in mindThe paid supporter pack advertises full-size card illustrations. KOTAMON DB links to official products and does not redistribute those paid files.
