Is Rate My Deck free?

Yes, and you don't need an account. The structural breakdown (lands, ramp, removal, card advantage, mana curve and the bracket estimate) is computed from your decklist and costs nothing. The AI written review is also free, with a limit per hour so one person can't exhaust it for everyone.

What decklist formats can I use?

A link to a deck on Archidekt, Moxfield or Manabox; a CSV exported from any of those sites; or a plain text list with one card per line in the form '1 Sol Ring'. If your commander is separated from the rest of the list by a blank line, as most exports do, it's detected automatically.

How is the bracket estimated?

By reading the list against Wizards of the Coast's official Commander bracket criteria: how many cards from the official Game Changers list it runs, how many tutors, how much fast mana, whether it has mass land denial or chained extra turns. It reports the lowest bracket your deck can honestly claim.

Why does it say 'at least' a bracket rather than giving one number?

Because a combo database can confirm a combo and can never prove there isn't one. Thassa's Oracle and Demonic Consultation are unremarkable on their own and are the whole deck together — those two are looked up and found, and the bracket moves accordingly. But only combos somebody has written up are in there, so a line specific to your commander, or one from a set nobody has covered yet, simply isn't. The count gives a floor you can trust; the AI review reads the list properly and refines it.

Do the numbers add up to 100?

No, and they're not meant to. A card counts toward every role it fills. Solemn Simulacrum is a creature and an artifact and ramp and card advantage all at once, so the totals overlap and sum well past your deck size. That's how deck builders count, and forcing one bucket per card would make most of the numbers wrong.

What does a good result look like?

Browse the published decks at /decks. Those are real lists people track games with, measured by the same counting this tool uses, so you can put your bracket and slot counts next to a deck that has actually won games and see where yours sits.

Do you store my decklist?

Yes. The list you submit is saved, along with which format you sent it in and what the analysis said. That's how we know how many people use the tool and what they're building, and it's what lets 'tune this deck in the app' hand your list straight over instead of asking you to paste it again. Nothing identifying you is stored with it: no account, no email, no IP address.

Decklist

One card per line. A blank line before your commander is detected automatically.

What you get

The shape of the deck

Every card is read for what it actually does, so a list becomes counts: how much ramp, how much removal, how many wipes, how much draw. Those are put next to what a deck of that archetype usually runs, with a tolerance band, so being one card off a target isn't a problem and isn't flagged as one.

A curve you can read

Your mana values bucketed against the shape the archetype wants, with your average next to its target. Lands are counted separately, because a land isn't a point on the curve. It's the thing that pays for it.

An honest bracket

Game Changers, tutor density, fast mana, land denial and extra turns, read against the official bracket criteria. It gives you the lowest bracket your list can honestly claim, a floor you can take to a Rule 0 conversation.

Cards can do more than one job

Solemn Simulacrum is a creature, an artifact, ramp and card advantage, and it counts toward all four. So the numbers overlap and add up to more than your deck size. That's deliberate, and it's how deck builders count.

The three things your deck is really built on

The written review names your deck's three strongest card interactions, and never a mana rock, because "you have more mana" isn't a synergy. Then it suggests three cards that extend those specific interactions, rather than the same staples every list gets told to run.

What turn it actually wins

An honest guess at the turn your deck closes a four-player game, read from your curve, how many pieces it needs and how resilient the line is, plus the one thing that would most move it earlier.
