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. With Premium, 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.
One number while you play. The reasons after.
During a game you only see your win chance, so the decisions stay yours. With Premium, advice comes once the game is over, when it can help your next one.
In draft and Sealed
While you pick and build
- A pick order for the first pack of each draft, ranked for the cards you've already taken.
- The same for packs 2 and 3, with grades and card notes. Premium
- The colours that are passing and the pairs your pool builds best. Premium
- Five decks built from your pool, one per colour pair, with a table made for Sealed when you play Sealed, each ready to copy into Arena. Premium
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 qualifiers and other competitive events.
After the game
When the match ends
- The turns where your win chance dropped the most, and the play that would have kept it. Premium
- A review of your draft picks. Premium
- Between games: your record by event, by deck and by the opponent's colours, your rank over time, and your Arena decks with their results. Premium
- Everything stays on your PC.
Ready in two minutes
Mana Odds reads the log file Arena writes on your PC. Nothing else.
-
Turn on detailed logs
In Arena, open Options, then Account, and tick Detailed Logs (Plugin Support). Restart Arena once.
-
Start Mana Odds
One program, no installer to click through. It finds Arena's window and places itself beside it.
-
Play as usual
Draft and play your games. With Premium, read the review when each one ends.
What you need
Mana Odds runs beside the Arena client for PC, on the same computer.
- Windows 10 or 11, 64-bit. With Microsoft Edge WebView2, which Windows already includes. Not on Mac or mobile yet.
- Detailed Logs turned on. In Arena: Options, Account, Detailed Logs (Plugin Support), then restart Arena once.
- Arena installed before you start Mana Odds. Install or update the Arena client for PC first, then start Mana Odds: it reads Arena's card database when it starts. See Start Mana Odds after Arena.
- Arena in a window or in borderless full screen. The overlay can't be drawn over exclusive full screen.
- Some processor time while you think. In a game it follows, while Arena waits for your decision, Mana Odds thinks for up to 20 seconds on up to half of your processor's cores (at most 8), then stops as soon as you play.
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 competitive events. Qualifiers, Arena Opens, Arena Direct, championships, showcases and tournaments get no live odds, and neither does a game whose event isn't known. The review after the game, with Premium, 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 how many cards they hold and 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 competitive 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?
Premier Draft, Quick Draft and Sealed with the current set, FRA. Constructed formats and other sets aren't followed yet: in those games there is no win chance and no review.
Does it work on Mac?
Not yet. Mana Odds needs Windows 10 or 11 (64-bit) and Microsoft Edge WebView2, which Windows already includes. See what you need.
Does Arena run slower?
Usually not. Mana Odds is a separate program and only reads files Arena already writes. During a game it follows, while Arena waits for your decision, it thinks for up to 20 seconds on up to half of your processor's cores (at most 8), then stops. On a PC with few cores Arena can feel slower in those seconds.
Something doesn't work. Who do I write to?
First see what to do if something doesn't work. Then 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.
