MTG: Top 6 Commander Deckbuilding Tools

Updated Nov 2, 2026, 5:56 PM EST Editor covering all things Magic: the Gathering, Pokemon, Yu-Gi-Oh!, and more. His favourite Pokemon is Porygon, and his favourite Commander is Karn, Legacy Reforged. Building a Magic: The Gathering Commander deck is a fun, albeit long process thanks to the more than 33,000 cards legal in the format. This is where online deckbuilding tools become priceless, because some of the best tools will take your existing decklist and suggest changes based on what you're trying to achieve. We've collated a list of six tools you should check out if you're preparing to build or adjust any of your Commander decks. Whether you're focusing on power level, price, or strategies, each of these tools will help you become a better deckbuilder, but don't ask them to help with missing your triggers. Updated on November 2, 2026 by Niall Walsh: We revisited this list after a long time to refresh it and add a relatively new tool to the list in EDHTuner. 6 EDHTuner One of the newer tools on the market is EDHTuner, which takes your existing deck (you can import it from other deckbuilding tools) and gives you valuable insights on which cards to remove and which to add, based on the strategies it detects in the current build. This AI-free tool also runs thousands of test games with each deck and each individual card replacement, so you can see how even small changes can affect a deck's performance. If you're worried about brackets, you can also see which bracket your deck falls into, and it can suggest ways to increase your deck's power level if you want to be more competitive or decrease it if you're looking to be fairer during casual games. Free, simple, and quick, EDHTuner has everything you need from a Commander deckbuilding tool, and as its feature set is built out and it potentially becomes less reliant on importing decks built in other tools, it could very well shoot up this list. 5 Commander Spellbook Commander Spellbook is "the search engine for EDH combos" and is a fantastic way to search for powerful combos. From the homepage, you can enter a card and find any combos that use it, or use advanced search to find combos by a specific outcome, your Commander's color identity, or even how many cards you need to pull it off. Commander Spellbook is great because it helps you tune your Commander deck to your playgroup's power level. You can use it to find combos to include, but you can also use it to pin down any accidental combos you didn't intend. There's nothing worse than somebody comboing off at a low-power game, especially when even that player didn't realize it could happen beforehand. 4 StrictlyBetter One quirk of the Commander format is that it's easy to use cards that do almost the same thing as another card, just slightly worse. For example, a Cancel and a Counterspell do the same thing, but Counterspell costs one generic mana less. That's what StrictlyBetter works out for you. The best time to use StrictlyBetter is after you've finished a rough draft of your deck and want to add a few finishing touches. Copy the decklist into the site, and it will scan its community-driven directories to see if any of your cards could be replaced with something better. The community votes on each suggestion, so you can easily see cards some people think are better but might not be the best alternative. Of course, Commander as a format is all about player expression. Don't feel as though you must be running the best possible card in every situation – Underground Sea may be better than a Sunken Hollow, but is also vastly more expensive, and maybe it's a step too far for your deck's power level. StrictlyBetter is just a good way to find easy improvements when you're struggling to know where to go next. 3 Moxfield There are lots of deckbuilding sites out there, like TappedOut, Archidekt, and MTGGoldfish, but Moxfield is by far the easiest and most powerful one of the lot. As a deckbuilding site, Moxfield's main goal is to help you organize and track your deck, draft new ones, or share them with other people. Through it, you can set the format you're building for, and it can help you avoid accidentally adding illegal cards. It can count your mana costs to help you get the right number of lands, track your mana curve to avoid unfortunate spikes in mana costs, and even look through other users' submissions for suggestions. One of the best things about Moxfield is how many ways you can organize your cards in the deck view. While you can stick with the default card type listing, you can group and sort your deck in loads of different ways, like mana cost, color, rarity, the set it debuted in, and even custom tags. It's so easy to tag cards as things like "ramp", "draw", or "removal" to ensure you're hitting everything a deck needs to be able to do. More than just a deckbuilder, though, Moxfield has lots of resources that help you test or improve your deck. It has full integration with EDHRec (more on that later), and even has a 'goldfishing' feature that helps you playtest your deck. 2 EDHRec EDHRec is the number one database for the Commander format, collating thousands of decklists together to make a resource that can help you build almost any deck possible. EDHRec ranks Commanders by popularity, which helps you see where the meta is, and it also shows which cards are most commonly played in that Commander's decks. For example, say you want to build a deck for Kwain, Itinerant Meddler. You can search for Kwain, and then scroll down to see all the top cards used in decks that run it as a Commander, like Dictate of Kruphix, Teferi's Ageless Insight, Kami of the Crescent Moon, and Laboratory Maniac. Each type of card is also individually listed, so if you're looking for lands to put in a Kwain deck, you can scroll to the lands section on EDHRec and see that Prairie Stream, Hallowed Fountain, Glacial Fortress, and Command Tower are the most popular. Alternatively, it can also sort by the themes of the deck you want to build, instead of a specific Commander. If you know you want to build a Planeswalker-heavy "Superfriends" deck, going to the Planeswalkers theme page shows you that Atraxa, Praetor's Voice, Carth the Lion, Esika God of the Tree, and Sisay, Weatherlight Captain are the most popular Commanders for it, while cards like Oath of Teferi and Nicol Bolas, Dragon-God are the most popular cards in the 99. EDHRec is a huge resource that can help take the decision anxiety out of making a deck. Whether you're looking for those last cards to add, or want inspiration for your next deck, it's one of the best community resources the Magic community has ever built. 1 Scryfall There are a lot of cards to sort through when building a deck. Though you could look through Gatherer, the official Magic database, Scryfall is a much more powerful alternative that's simultaneously a lot easier to use. From the homepage, you can search through the names of any card ever published. For example, typing "Dig" can show you Dig Through Time, Gravedigger, Harmonic Prodigy, Dig Up, and more. This is great for finding a specific card you want to check; it also shows official rulings, images of most prints, what sets it's legal in, and even secondary market prices. But individual cards are just the tip of the iceberg of what Scryfall can do. The advanced search is incredible, and through it, you can search through every card's rule text, flavor text, color identity, look up full set galleries, find specific artists, and even find which cards mention your favorite characters. There are loads of unofficial categories to look through as well, such as whether a card's double-sided, has an etched foil version, has hybrid mana, or virtually anything else you could want to look for. For most deckbuilding, the most important things to search by are the text field, which searches the main rules box on every card, colors to find the right color cards for your deck, and the type line to weed out creatures from sorceries, or look for the exact creature type you want. Scryfall is an absolute powerhouse of a tool. It might take a little while to get to grips with its quirks and syntax, but once you have, finding exactly what you need for any deck is a breeze.
