Set Checklists & Card Details

Each set page offers two complementary views:

Checklist View

Default view. Cards grouped by Subset with all variants collapsed under their base card. Desktop shows a paginated table (10/25/50/100 per page). Mobile shows a 2x2 carousel with snap-scroll.

Parallel Run View

Select a specific VariantName (e.g. "Gold Foil") to see every card in the set that has that parallel. Perfect for tracking completion of a single parallel across the entire set.

The GroupKey is the system's way of linking all versions of the same base card together. A single GroupKey ties together:

• The base card (IsVariant=false)
• Every parallel version (IsVariant=true) with names like Gold, Red Foil, Canvas, Rainbow, Holofoil

When viewing a card, click Show Parallels to expand all sibling variants inline via AJAX. Each variant shows its own SerialDenominator (print run, e.g. /25, /199) and ItemType.

The ItemType field defines the nature of each card:

Base

The standard version — the foundation of the set checklist

Insert

Special limited-release cards with unique designs, not parallel variants

Parallel

Alternate finish/foil version of a base card

Autograph

Signed card, often in a lower print run

Memorabilia

Contains physical relic pieces (worn patches, etc.)

Sketch

Original artist sketch card, typically 1-of-1

Promo

Promotional card not part of the main set release

Correctly identifying the ItemType helps track rarity tier and collection value.

Card images follow a standard URL pattern based on the set's ImageFolder and each card's FrontImageId / BackImageId:

https://images.cardboardempires.me/{ImageFolder}/{FrontImageId}.jpg

Images are served through Cloudflare R2. If a card appears without an image, it may not have been scanned yet — the database contains checklist data before images are captured.

The WhereToGet field on each card indicates retail availability: Hobby, Value, Mega, e-Pack, Retail, or other product lines. This helps identify which product types contain specific cards or parallels.

If you notice data discrepancies, visit the FAQ section for reporting instructions.

Cardboard Empires provides a printable Card Capture Sheet designed to help you scan cards quickly and consistently. The sheet uses four fiducial markers (FID 17-20) at the corners for automatic perspective correction and card slot detection.

How to Use the Capture Sheet:

1. Print the sheet at 100% scale on letter paper (8.5" × 11").
2. Place the sheet on a flat, dark, non-reflective surface.
3. Arrange your cards face-up in the six labeled slots (A1 through C2). Horizontal cards only.
4. Photograph the sheet with your camera, ensuring all four fiducial markers are visible in the frame. Use even lighting to avoid glare and shadows.
5. Upload the photo through the Card Capture pipeline. The software detects the fiducial markers, corrects perspective, and extracts each card automatically.
6. Review the extracted card images. Flip cards over and repeat for the back sides.

For a detailed walkthrough of the card image submission process, check out the video guide below.

If you run into issues, make sure the sheet is printed at exactly 100% scale (not "fit to page"), the lighting is even, and all four corner fiducials are fully visible.
