Best MTG Deck Builder Sites Compared (2026)

Picking the best MTG deck builder site feels like picking a commander. Everyone has opinions, nobody agrees, and you'll probably end up trying all of them before you settle. I've spent real time building decks on every major platform in 2026, and the honest answer is that no single tool does everything perfectly. They all make tradeoffs.

This isn't a ranking where I tell you Moxfield wins and call it a day (though it probably will for most people). Instead, I want to break down what each site actually does, who it's for, and where it falls apart. If you're trying to figure out which MTG deck builder site deserves your time, this should save you a few hours of frustrated clicking.

What makes a good deck builder site

Before we get into the tools, here's what I'm evaluating:

• Editor speed. How fast can I actually build a deck? Auto-complete, drag-and-drop, text paste support.
• Analysis tools. Mana curve, color distribution, probability calculations, format legality checks.
• Import and export. Can I move decks between platforms, Arena, MTGO, or send a list to a store?
• Collection tracking. Can the site also track what I own?
• Playtesting. Can I goldfish a starting hand?
• Mobile experience. Does it work on a phone or is it desktop-only in practice?
• Pricing. What's free, what costs money, and is the paid tier worth it?

Every tool gets measured against those criteria. Let's go.

Moxfield: the default for a reason

Moxfield has become the go-to deck builder for most of the MTG community, and it's earned that spot. The editor is fast, the interface is clean, and deck sharing is painless. When someone posts a deck link on Reddit or Discord, it's almost always Moxfield.

What it does well. The deck editor and the deck view live on the same page, so you're never bouncing between screens to see your changes. Auto-complete is responsive. You can sort by custom categories, view your deck as text or card images, and the mana curve visualization updates in real time. The playtester has solid hotkeys that make goldfishing a few hands quick and natural.

Moxfield also supports "packages," which let you save groups of cards you frequently slot together. If you're always adding the same ramp package to your Commander decks, this saves real time.

Where it falls short. Collection tracking exists but it's minimal. You can't share entire folders of decks (only individual deck links), which is annoying if you maintain a library of builds. And while the site is "free," Moxfield runs on Patreon support with tiers starting at $1/month. Core features remain free, but you're relying on goodwill for that to continue.

Pricing. Free core. Patreon tiers from $1/month for supporter perks.

Best for: General purpose deck building, sharing decks with your playgroup, competitive formats where you want clean presentation.

Archidekt: the brewer's playground

Archidekt gets a bad rap in comparison articles, but I think that's unfair. It's genuinely better than Moxfield for certain workflows, and the community on Reddit is increasingly vocal about why.

What it does well. Archidekt's auto-categorization is the standout feature. Drop a bunch of cards into a Commander deck and it will automatically sort them into functional categories like "Removal," "Ramp," and "Card Draw." You can customize these categories or use its suggestions. For brewers who like to see their deck's role distribution at a glance, nothing else comes close.

The bracket system ranking is another Archidekt exclusive that matters in 2026. With Commander brackets becoming more relevant to playgroups, Archidekt gives you a comprehensive bracket score for your deck that accounts for optimization level and combo potential. Moxfield has nothing comparable.

Archidekt also supports drag-and-drop in the editor, real-time stat updates, and prices from TCGPlayer, Card Kingdom, Cardmarket, and Cardhoarder.

Where it falls short. The editor overlay can feel cramped, especially on smaller screens. The playtester is clunky compared to Moxfield's. Cards bounce around when you scroll, and the battlefield gets messy fast. The learning curve is steeper than it needs to be for new users.

Pricing. Free core. Patreon at $2/month removes ads.

Best for: Commander brewers who want auto-categorization and bracket scoring. If you build more decks than you play, Archidekt is probably your tool.

MTGGoldfish: better for research than building

MTGGoldfish is one of the most popular Magic sites on the internet, but its deck builder is not why people visit. They come for the metagame data, price tracking, and articles. The deck builder is more of an afterthought.

What it does well. Meta analysis is unmatched. You can see exactly what's winning in every format, track deck price trends over time, and their content team produces some of the best MTG writing online. The SuperBrew feature (premium) helps you find decks to build based on cards you already own, which is a smart concept.

MTGGoldfish also has over 3 million submitted decks, so the searchable database alone makes it worth bookmarking.

Where it falls short. The actual deck building experience is painful. Editing a deck involves multiple page loads. The interface looks dated. There's no real-time stat updating while you edit. If you're used to Moxfield or Archidekt, going back to MTGGoldfish's editor feels like going back to dial-up.

Pricing. Free tier with ads. Premium at $6/month adds SuperBrew, unlimited card tracking, price alerts, collection import, and price history downloads.

Best for: Competitive players who want metagame research and price tracking. Build your deck here if you're netdecking from tournament results, then export it to a better editor for tweaking.

TappedOut: the one your playgroup used in 2015

TappedOut was the deck builder for a generation of Magic players. If you started playing Commander between 2010 and 2018, you probably built your first deck here. The site still has active forums and a loyal community, but the interface hasn't kept up.

What it does well. TappedOut has genuine community features that newer sites lack. The forums are active with deck building discussion, rules questions, and custom card design threads. The deck comment sections get real engagement. There's a charm to the old-school layout if you're nostalgic for it, and the dark theme is easy on the eyes during late-night brewing sessions.

Where it falls short. The editor lacks auto-complete, which in 2026 is inexcusable. The UI looks like it was designed during the Bush administration and hasn't been updated since. No drag-and-drop. Limited deck analysis tools. The site is slow to load and occasionally buggy. It's hard to recommend TappedOut to anyone who hasn't already invested years of decks into the platform.

Pricing. Free with ads. Premium removes ads and adds some features.

Best for: Players who already have their collection there and like the community forums. Everyone else should move on.

Deckstats: the data nerd's choice

Deckstats doesn't try to look pretty, and that's kind of the point. It's a utilitarian deck builder that prioritizes data analysis over visual flair.

What it does well. The probability analysis is the best of any deck builder I've tested. Want to know the exact chance of drawing one of your two copies of Swords to Plowshares by turn three? Deckstats will tell you. The mana curve, card type distribution, and mana source breakdowns are all presented clearly at the top of each deck page. Folders and sub-folders let you organize decks in ways that other sites don't support.

The collection manager lets you add notes per card via CSV import, which is a niche feature that no other tracker offers. If you maintain a spreadsheet alongside your collection, Deckstats integrates with that workflow.

Where it falls short. The design is plain to the point of being unappealing. New users will struggle to find where their decks are stored. The site doesn't look modern, and while that's fine for experienced users who value function over form, it's a hard sell for anyone used to Moxfield's polish.

Pricing. Free with ads. Supporter tier available.

Best for: Statistical analysis of your decks. If you care about probabilities and mana base math more than aesthetics, Deckstats is the best tool available.

Scryfall: the card database that also builds decks

Scryfall is the backbone of MTG online. Almost every other deck builder site pulls its card data from Scryfall's API. Most people don't realize it also has a built-in deck builder.

What it does well. Scryfall's search syntax is the most powerful card search tool available, period. Want to find every green creature with mana value 3 or less that has an ETB trigger? You can write that query. The fuzzy matching on card names is remarkably good at guessing what you meant even when you butcher the spelling.

The deck builder itself is simple and fast. Add cards, export the list, done. No frills, no friction.

Where it falls short. There's almost nothing beyond basic deck creation. No mana curve analysis. No playtester. No collection tracking. No community features. Scryfall is a search engine that happens to let you save lists, not a full deck building platform.

Pricing. Completely free. No premium tier. Funded by donations.

Best for: Searching for cards and quickly putting together a rough draft of a deck. Export to another tool for actual analysis.

AetherHub: the Arena player's companion

AetherHub carved out its niche by focusing on MTG Arena integration, and it does that well.

What it does well. The MTGA Assistant browser extension and Overwolf app let you import your Arena collection automatically, track your draft and constructed results, and see metagame data pulled directly from Arena matches. The meta pages break down what's winning in Standard, Historic, and other Arena formats with deck lists and win rates sourced from actual games.

The deck builder supports visual editing, set and format filtering, and easy import/export with Arena's deck format.

Where it falls short. If you don't play Arena, AetherHub has less to offer. The community is smaller than Moxfield or TappedOut. The deck analysis tools are basic compared to Deckstats. And the site is ad-heavy on free accounts.

Pricing. Free with ads. Premium tier available for ad removal and extra features.

Best for: MTG Arena players who want metagame tracking and seamless Arena integration.

ManaStack: the multiplayer playtester

ManaStack would be a footnote on this list if it weren't for one standout feature: multiplayer playtesting.

What it does well. Most deck builders let you goldfish against yourself. ManaStack lets you playtest against other people in real time. The playtester works similar to Cockatrice, with a shared virtual table where players manually tap, draw, and resolve cards. It's not rules-enforced, but the ability to test your brew against another human's deck without installing separate software is unique.

The visual deck builder is drag-and-drop and reasonably intuitive. The card database is complete and up to date.

Where it falls short. The deck analysis is basic. The community features (discussions, social elements) are poorly organized. ManaStack charges $5/month for AI-assisted deck building and matchmaking in the playtester. At that price, you could download Cockatrice for free and get a similar (arguably better) multiplayer testing experience.

Pricing. Free core. $5/month for AI deck building and matchmaking.

Best for: Players who want to playtest against others in a browser without installing Cockatrice or paying for MTGO.

GrimDeck: deck builder meets collection tracker

Full disclosure: this is our site. I'm going to be straight about what GrimDeck does differently and where it's still catching up.

GrimDeck was built to solve a problem that bugged us about every other tool on this list: none of them combine a proper deck builder with a proper collection tracker in a single, unified experience. Moxfield's collection features are an afterthought. Deckstats has CSV import but no scanning. MTGGoldfish locks collection features behind a $6/month paywall.

What it does well. GrimDeck is a combined deck builder and collection tracker from the ground up. You can scan physical cards with your phone camera to add them to your collection, then build decks that reference what you actually own. The auto-deck builder generates a starting deck list from your collection for a given commander or format, which saves time when you're trying to figure out what you can build with the cards in your binder.

Deck analysis includes real-time mana base recommendations, color requirement visualization, curve analysis, and format legality checks for Standard, Modern, Pioneer, Legacy, and Commander. Price tracking shows your deck's total cost and highlights budget alternatives for expensive cards.

Where it falls short. GrimDeck is newer and smaller than the established platforms. The community is still growing, so you won't find the deck diversity or discussion volume of Moxfield or TappedOut. No playtester yet (it's coming). The card scanning works but isn't as fast as ManaBox's dedicated mobile app.

Pricing. Free tier available. Premium at $3.99/month or $39/year adds advanced collection analytics and premium deck features.

Best for: Players who want their deck builder and collection tracker in the same place, especially if you're building from what you own rather than buying new cards for every deck. The auto-deck builder is genuinely useful for Commander players on a budget.

So which deck builder should you actually use?

There's no single answer, but here's how I'd think about it:

If you just want to build and share decks, use Moxfield. It's the standard for a reason. Clean, fast, free, and everyone can view your links without creating an account.

If you brew more than you play, Archidekt's auto-categorization and bracket scoring will speed up your process. The learning curve is worth it for heavy Commander brewers.

If you care about data, Deckstats gives you probability analysis and organizational depth that no other free tool matches.

If you play Arena competitively, AetherHub's MTGA Assistant and metagame tracking are worth setting up alongside whatever desktop builder you prefer.

If you want to build from your physical collection, GrimDeck is the only tool that genuinely combines deck building and collection tracking with card scanning. Most other sites treat collection management as a premium add-on or ignore it entirely.

If you're a data hound who wants metagame research, MTGGoldfish is indispensable for tournament results and price trends, even if you never touch its deck builder.

Realistically, most serious players end up using two or three of these tools. I use Moxfield for sharing decks with my playgroup, Scryfall for card searches, and GrimDeck for tracking what I actually own. Find the combination that fits how you play and stop worrying about picking the "right" one.
