See your chance of winning, every turn.

Mana Odds sits beside MTG Arena and shows how likely you are to win the game you're playing. When the game ends, it shows the turns where it slipped and what would have done better.

For Windows 10 and 11. Free during the beta.

Your win chance, turn 10 93%
After the game, turn 4: blocking with the 3/3 instead of trading with the 2/2 cost you 9 points of win chance.

One number while you play. The reasons after.

During a game you only see your win chance, so the decisions stay yours. Advice comes once the game is over, when it can help your next one.

In the draft

While you pick

  • A pick order for every pack, ranked for the cards you've already taken.
  • Your colours and curve as the pool grows.
  • A suggested deck when the draft ends.

In the game

Every turn

  • Your live chance of winning, from a neural network trained by playing against itself.
  • Docks beside Arena or floats over its edge, at the opacity you choose.
  • Switches itself off in events with prizes.

After the game

When the match ends

  • The turns where your win chance dropped the most, and the play that would have kept it.
  • A review of your draft picks.
  • Everything stays on your PC.
In development An overlay over Arena, also in full screen: cards left in your library and the chance of drawing a land, the cards your opponent has shown, ratings on the draft screen, your win rate by deck and event, rank and limited runs.

Ready in two minutes

Mana Odds reads the log file Arena writes on your PC. Nothing else.

  1. Turn on detailed logs

    In Arena, open Options, then Account, and tick Detailed Logs (Plugin Support). Restart Arena once.

  2. Start Mana Odds

    One program, no installer to click through. It finds Arena's window and places itself beside it.

  3. Play as usual

    Draft, play your games, and read the review when each one ends.

Built to follow Arena's rules

Wizards of the Coast allows tools that work like a notepad, not ones that play for you. Mana Odds is designed around that line.

  • No moves during a game. Live, you see one number: your chance of winning.
  • Off in prize events. Qualifiers, championships and other events with prizes get no live odds. The review after the game stays.
  • Only Arena's own log. No reading of the game's memory, no injected code, no automation.
  • Hidden information stays hidden. Your opponent's hand and library are never shown, only what the game has revealed.

Questions

Is it allowed to use Mana Odds on Arena?

Wizards of the Coast allows third-party tools that track information, as long as they don't make decisions for you, don't read the game's memory and don't run in events where outside help is banned. Mana Odds shows no moves during a game, reads only Arena's log and switches its live odds off in prize events.

How does it know my chance of winning?

A neural network trained by playing against itself looks at the board, the cards you hold and what your opponent has shown, and estimates who is ahead. It sees only what you can see.

Which formats does it support?

Draft, starting with the current set's Premier and Quick Draft.

Does it work on Mac?

Not yet. Mana Odds needs Windows 10 or 11 and Microsoft Edge WebView2, which Windows already includes.

Does Arena run slower?

No. Mana Odds runs as a separate program and only reads a text file Arena already writes.

Something doesn't work. Who do I write to?

Write to support@manaodds.com with what you were doing, and attach the file Player.log from %USERPROFILE%\AppData\LocalLow\Wizards Of The Coast\MTGA if Arena is involved.
