For Commander players
Better decks from the cards you already own.
The Commons reads your decks and your collection, then shows the upgrades sitting in your binders, the combos you’re one card from, and where each deck lands on Wizards’ brackets.
Free to use. No ads, no trackers. Sign in with your email, Google or Discord.
Look around
Every card, and the decks players share.
No account needed. Look up any card for its printings, prices and the combos it’s in, or open a deck someone built.
Tune this deck
Upgrades from your own binders.
Tell The Commons what the deck should do, in your words or with a plan like Aristocrats or Landfall. It ranks the cards you already own first, then the ones worth buying.
- Suggestions from your collection, marked with how many copies you own
- Cards you own by default; let it suggest buys too, capped at $1, $5 or $20
- Each pick says why: the combo it completes, the plan it fits, the deck’s ramp it shares
Collection
Watch what your collection is worth.
Every card you own is priced every day. See the total move, then open any binder, deck or set, like everything Final Fantasy, to see its own value and chart.
- Value over a week, a month, three or six months, with the change in dollars and percent
- Binders, decks and sets, each with its share of the total and how it moved
- Top gainers, biggest drops and your most valuable cards
- A year of history and all time Pro
Combos
Find the combos hiding in your pile.
Every combo in your deck, and every one you’re a single card from, checked against more than 100,000 known combos.
- Complete combos and one-card-away combos, side by side
- What each combo makes, what it needs on the battlefield, and the steps
- The missing piece’s price, so you know what finishing it costs
- Combos across your whole collection, not just the deck Pro
Bracket check
Know your bracket before you sit down.
The Commons measures your list against Wizards’ Commander brackets and shows its working, so the conversation before the game is a short one.
- Game Changers, two-card combos, extra turns and mass land denial, each counted
- Every card that moves the estimate, listed by name
- Show only the Game Changers in one tap, or set the bracket yourself
Cards to acquire
Know what to buy, and why.
A shopping list ranked for this deck: combo pieces you’re one card from first, then the cards players run most with your commander. Open any card to see exactly how it scored.
- Score = fit with your commander and the rest of the deck, plus the combos it finishes, adjusted for the mana curve
- Write the deck’s goal and cards that serve it rank first
- Buy on TCGplayer or Cardmarket straight from the card
Your deck
Your deck, laid out like a table.
Stacks by category or type, a running price, the mana curve, and the tokens the deck makes, with the cards that make each one.
- Prices from TCGplayer, Card Kingdom or Cardmarket, whichever you buy from
- List or stacks, by type or by your own categories
- Keep a theorycrafted deck beside your real ones without it claiming your cards
- Every add and cut by date, with one-tap restore Pro

Questions
Is The Commons free?
Yes. Decks, imports, combos in your deck, the bracket check, Cards to acquire, Tune this deck, Mulligan Lab hands and your collection’s value over six months are free. Commons Pro adds Commons AI, cross-deck swaps, commanders you could build, combos across your whole collection, Mulligan Lab odds, deck history and longer price history.
Is there a phone app?
Not yet. The Commons runs in your browser today, on a computer or a phone. Apps for iPhone and then Android are on the way, with the same account, decks and collection as the website, so you can build at your desk and check a deck at the table.
What is Commons AI?
An assistant inside The Commons that knows your decks and your collection. Ask what to cut, what to add, or which cards you already own would fit, and it answers with real cards. It’s part of Commons Pro, for players 18 and older, and it only talks about Magic. Like any AI it can be wrong, so check a change before you make it.
Do I need to enter my whole collection?
No. Start with a deck. The more of your collection The Commons knows, the more of its suggestions are cards you can sleeve tonight instead of cards to buy.
How do I get better suggestions for a deck?
Give the deck a description: what it does and how it wins, naming any key cards. Add it when you make the deck, or later in the deck’s settings (select the deck’s name at the top of its page). Tune this deck, Cards to acquire and the optimizations between your decks then rank cards by how well they serve that plan, so the loose cards in your binders and the ones sitting idle in your other decks that fit it come first. Without a description, The Commons reads the plan from your commander’s own text.
How do I get good scans?
Lay the card flat on a plain surface in even light and keep your phone steady above it. A phone stand made for scanning trading cards, which holds the phone at a fixed height over the card, gives the most consistent results. Holding a card up in front of the camera is less reliable: it moves, tilts and catches glare. Make sure the card’s name is in focus and free of glare, and take foils out of shiny sleeves if the name won’t read.
Can I bring decks from another site?
Paste the decklist or the deck’s link. For a collection, export a CSV from the app you use now and import the file.
Which format is it for?
Commander first: the bracket check, the combos and the suggestions are all built around it.
How do I sign in?
With a code we email you, or with Google or Discord. Sign in with Apple comes with the iPhone app.
Where do prices come from?
TCGplayer, Card Kingdom or Cardmarket. Pick the one you buy from in Settings.
Is this made by Wizards of the Coast?
No. The Commons is unofficial Fan Content, not approved or endorsed by Wizards.
