Commander Deck Builder
Build and import MTG Commander decks, organize cards by role, check your mana curve, and see which cards you own or still need.
Open your decksStart with a commander or bring an existing list
Create a deck with your chosen commander, or import a list you already use. ElderDecks supports pasted deck lists and supported Moxfield and Archidekt links. Review the import preview before saving: unavailable editions or finishes may need a known replacement, and source-site access can sometimes prevent a URL import. Partner commanders and separate basic-land printings can be retained without counting cards twice.
Import a deck listOrganize the deck around its game plan
Use stacks, a grid, or a list to work through your cards. Automatic categories help separate roles such as ramp, draw, removal, and protection; manual categories let you organize a deck your own way. Filter the deck, compare mana costs, and adjust quantities as you refine it. The lightning-bolt badge identifies Commander Game Changers, but a deck's strength still depends on the full list and how your group plays.

Ownership is more useful when it accounts for the decks you already have assembled. Collection allocation distinguishes available copies from cards spoken for by another deck. Compare the cards you own with the copies your next build needs, review editions, and use estimated prices as a planning tool. Prices can change and should be checked with the retailer before buying.
Explore collection trackingTest the list before your next game
Open the deck's playtester to try opening hands and sequence your cards. Choose solo testing or optional simulated opponents while keeping control of your own deck. For a game with friends, take a saved deck into a multiplayer lobby. The multiplayer table synchronizes your play, while your pod handles decisions and Magic rules rather than relying on a fully automated rules engine.
