        "shortDescription": "Commander, EDH decklist price",
        "longDescription": "Paste any Magic: The Gathering decklist (MTG Arena, MTGO, Moxfield or Archidekt export, or a plain list) and see what it costs: the price of every card at its cheapest printing and at the printing in your list, in US dollars, euros and MTGO tix, with the deck and sideboard totals. The same check catches what AI-built lists get wrong: cards that do not exist (with the closest real names), banned and not-legal cards, a Commander deck that is not exactly 100 cards, extra copies, cards outside the commander's color identity, and the number of Commander Game Changers for brackets. You also get the mana curve, color pips against mana sources, card types and deck roles such as ramp, card draw and removal. Budget mode finds the cheapest printing of each expensive card and cheaper cards that do the same job, in your colors and format, under the price you choose, while keeping the cards you name as the core of the deck. Card data, images and prices come from Scryfall and are refreshed daily; prices are market estimates, not store offers. No account needed.
