Design a complete, coherent custom card set — from a spreadsheet.

Unicards is an editor for Magic-style fan sets. Your card list lives in a keyboard-friendly grid (or a CSV / Google Sheet); every edit updates the card preview and the balance of the whole set. When it's ready, print it. Free, no account needed.

The Unicards editor: a spreadsheet of cards, a live card preview and set statistics

Who it's for

Homebrew set designers

Fill the gaps of your cube with custom cards and see the curve per color at a glance.

Playtesters

Turn a list into printable proxy sheets of your own designs in one click.

Content creators

Prototype spoilers and fun sets for videos, streams or a community challenge.

Game designers

Prototype a card game fast: tweak numbers in a grid, check the stats, print, playtest, repeat.

Everything a set needs, nothing in the way

▦

Keyboard spreadsheet grid

Arrows, Tab, Enter, copy/paste with Google Sheets and Excel, fill-down. Import and export CSV; Google Sheets sync is on the way.

◐

Compact mana notation

Type 1RR, hybrid ug, Phyrexian up or twobrid 2w; mana value and color identity are computed for you.

▣

Live preview

Every card renders as you type, with trim and safe-zone guides. Your set's keywords get their reminder text printed when it fits. Automatic ids and collector numbers.

▥

Set balance stats

Mana curve by color, rarity per color, card types and subtypes — spot the holes before your playtesters do.

⎙

Print-ready output

3×3 PDF sheets on A4 or Letter with 3 mm bleed and crop marks, plus PNG export of single cards.

✦

Mechanics, factions & art

Define your set's mechanics with reminder text, note each color's faction and themes, and use your own illustrations — uploaded or linked.

How it works
