Tracker, Draft Assistant, decks and statistics for MTG Arena.

During a match it counts the cards left in your deck. In Draft it ranks every pack and suggests your final deck. Afterwards it keeps your decks and their statistics. On the web you'll find the Meta, Draft data and your account.

What MOX does

Four moments of an Arena session. Every image below is a screenshot of the app as it is today.

  1. During the match

    In-game counter

    It opens over Arena and keeps count of the cards left in your deck: how many copies, how many lands, how likely you are to draw each one. A second panel lists the cards your opponent has already revealed.

    It does not tell you what to play: it keeps count for you.

    Real screenshot. On the left your deck panel; in the inset, your opponent's.

  2. During the Draft

    Draft Assistant

    Open it before you join the Draft. For every pack it ranks the cards, with the win rate from 17Lands data and a plain verdict: strong card, good in your colours, filler.

  3. After the Draft

    Draft Assistant

    When the Draft ends it suggests the deck to build from your pool: the main colours, three combinations side by side and how many lands to play, from 16 to 18.

    Draft finished: MOX suggests a 40-card black-red deck, with two alternatives and the number of lands.

  4. After your matches

    Your Arena decks

    Your decks stay on your PC, with statistics for every version: matches, wins, on the play and on the draw, format by format. You compare them with your collection, copy them to the clipboard or save them to a file to share with a friend.

MOX on the web

The site shows the data that can be published and, if you sign in, your personal archive. It works even with the app closed.

The Meta Explorer: filters for format, period, mode, rank, strategy and colours, and the archetype table with matches, win rate and meta share.
An archetype page: summary and variants observed on MOX, published and below threshold. A variant's detail: win rate, record, matches, meta share and the published decklist.

Site screenshots with public Meta data: from the Explorer to the archetype, from the archetype to its variants.

Meta

Filter archetypes by format, period, rank, colour and strategy. From each archetype open the variants observed on MOX and, once they pass the threshold, their decklist.

Research and upcoming work

Participation in MOX Research is already available in beta. Research analyses, results and suggestions are still in development and have no release date.

  • Available in beta · MOX Research participation

    You can choose to contribute from Settings. It is optional, off by default, and you can leave at any time.

  • In development · MOX Research analyses and suggestions

    We want to use match data to find interesting deck changes worth testing. MOX can suggest a hypothesis; real matches on Arena must confirm whether it actually works.

  • Draft Assistant Next Gen

    A clearer path from the pick to the pool to building the final deck.

  • New interface

    A new desktop experience: more modern, clearer and consistent with the rest of MOX.

Planned

Ideas lined up for later, without dates. They may change.

  • Collection and missing wildcards

    Which cards you are missing to complete a list, and how many wildcards you need.

  • “Can I build this deck?”

    A clear answer before you spend wildcards.

  • A fuller deck editor

    More tools to edit lists inside MOX.

  • Card search and deck building without Arena

    Search cards and build a deck even with Arena closed.

  • Deck sharing

    A controlled way to pass a list to friends.
