Coming soon

DeckLogic is in active development. The first public installer will be available here — sign up on GitHub to be notified the moment it lands.

What starting it looks like.

DeckLogic attaches to Arena's log and reports what it found. This is the real startup screen — no account, no upload, nothing to configure first.

What you'll get.

Descriptive in-match tracking

Win expectancy, draw odds, lethal indicators, and revealed cards — shown during the game, never prescribing your play.

Post-game coaching

Graded decisions, Film Room replay study, practice drills, and a mastery shelf — all after the match concludes.

Limited assistant

Pick scores on the real pack, deck builder with consistency lab, post-draft recap, and offline practice drafts.

System requirements

Windows 10/11 (64-bit) · MTG Arena installed · WebView2 runtime (preinstalled on Windows 11). macOS and Linux builds are not offered yet.

Optional extras

Announcer voice

One click in Settings downloads the Kokoro neural TTS voice bundle, with progress. No manual file wrangling.

Generative commentary

Run Ollama (ollama pull phi3) or LM Studio locally and the announcer composes fully unscripted lines. Without one, a built-in semantic compiler takes over.

Both optional — the app is complete without them.
