A Commander deck builder that does more than list cards
Most tools just let you stack cards in a box. Leyline is a Commander deck builder and deck manager in one — a place where your decks don't just exist, they get better. Import any EDH decklist from Archidekt in a single tap, organize your whole library of builds, and let our AI deck optimizer tell you exactly how strong each one really is.
Behind every build, Leyline runs an AI-powered scoring model across Power, Salt, Fear, and Airtime, detects combos, and tracks full version history so you can see how your deck evolved over time. It's the online MTG deck builder built for players who want to build, score, and dominate — not just keep a spreadsheet of cards.

Your decks, perfected — and never lost
Already living on Archidekt? Bring it all with you. Archidekt sync pulls your full decklist — commander, cards, and categories — into Leyline with a single tap, so you never have to rebuild from scratch. Re-sync anytime to pull the latest edits, and keep using the deckbuilding workflow you already know.
Once a deck lives in Leyline, every meaningful change is captured as a deck version. That means complete version history for each build: compare two versions side by side, roll back an edit you regret, and see exactly which swaps moved your power score. As an mtg deck tracker and commander deck manager, Leyline makes sure no good build — or good idea — ever gets lost.
An AI deck optimizer that shows you what to fix
A pile of cards is easy. A great Commander deck is hard. Leyline's AI deck building engine reads your entire list and scores it across four dimensions — Power for raw strength and speed, Salt for how frustrating it feels to face, Fear for threat density and table pressure, and Airtime for how interactive and grindy your games run.
From there the mtg deck optimizer goes to work: it detects combos, flags a shaky mana base, checks your curve, and spotlights the cards quietly carrying your build alongside the dead weight dragging it down. Swap in upgrades, rescan, and watch your deck power score climb. Whether you're tuning a casual brew or an EDH deckbuilding project bound for a high-powered pod, you build with data instead of guesswork.
MTG deck building, answered
What makes Leyline a great MTG deck builder?
Leyline is a full Commander deck builder and deck manager in one. You can import any decklist from Archidekt in a single tap, organize your entire collection of builds, track every version over time, and optimize each deck with AI-powered scoring across Power, Salt, Fear, and Airtime.

How does Archidekt sync work?
Paste an Archidekt deck URL or link your account and Leyline pulls the full list — cards, categories, and commander — in one tap. From there it lives in your Leyline deck manager, where you can score it, version it, and optimize it. Re-sync anytime to pull the latest changes from Archidekt without rebuilding from scratch.
Can I track version history for my decks?
Yes. Every meaningful change is captured as a deck version, so you have complete version history for each build. Swap a card, rescore, and compare — you can see how your Commander deck evolved over time, roll back a change you regret, and understand exactly which edits moved your power score.
How does AI deck building and optimization work?
Leyline reads your full decklist and runs it through an AI-powered deck optimizer that scores Power, Salt, Fear, and Airtime, detects combos, and flags weak spots in your curve and mana base. It surfaces the cards quietly carrying your build and the dead weight dragging it down, so you can tune your EDH deck with data instead of guesswork.
Is the online MTG deck builder free to use?
Yes. You can build, score, and optimize Commander decks for free. A free account lets you sync from Archidekt, save unlimited builds, track version history, and revisit your deck scores anytime. You can even scan a deck for free before you sign up to see how the deck builder and optimizer work.
Can I export my decks?
Yes. Any deck in your Leyline deck manager can be exported as a clean decklist, so you can share it, print a proxy sheet, or move it to another platform. Combined with Archidekt sync, Leyline fits neatly into whatever deckbuilding workflow you already use.
