when you want more detail. The current decision separates your response from the opponent's priority.
See whether you're playing, Autoplay is acting, or the board is being reassessed. A green line marks the leading supported path. Expand an alternative to inspect its
actions and projected life totals. Inspecting a path doesn't change Autoplay's choice. The outlook tilts as the board assessment changes. It is a heuristic read of the
position, not a percentage chance of winning. A leading path can still be a projected loss. When the board changes, Coach withdraws the old forecast while it reassesses.
Future draws and unknown opponent spells are outside the modeled paths. Illustration: choose a position to see the balance move.
The app's outlook animation can also be turned off. Illustrative outlook You ahead Board assessment · not a win probabilityA coach in your ear.

A moving balance, not win odds
Speech & voices
Choose spoken Coach advice or two ArenaOnAir announcers inside Coach. Pick a voice pair and a style independently.
Hype
Playful reactions and rising energy for consequential plays. The play-by-play caster calls the action; the analyst explains how the position and each player's route to winning change.
Technical
Measured delivery, dry wit and precise analysis. Hear about pressure, resources, interaction windows and the choices that could turn the match.
Choose Chatterbox in Speech & voices to use hosted speech with your Coach access. Kokoro remains available for local speech. Player decisions and urgent prompts take priority over background commentary.
Looking for the standalone broadcast app? Visit ArenaOnAir. Your Patreon key works there too.
Across the match
Coach reads the game information Arena exposes in its log and talks through attacks, blocks and sequencing. Deck playbooks give the plan a starting point before the first draw.
Surrak and Goreclaw is already down — move to combat and swing with everything for lethal.
Pick advice combines card text, your pool and 17Lands data. Get help with the final build, including cuts, or with a sealed pool.
Choosing Way of the Wildspeaker: it works with our Inspired Tethermage and Kiora of Salt and Sand.
With the platform bridge connected, Autoplay submits lands, spells, targets, attacks and blocks to Arena. Enable auto-queue to continue with your selected deck and queue.
Some decisions can still require your input. Coach surfaces a manual handoff when it cannot safely continue.
Expand the hand, board or activity without crowding the current decision. Open match history to review results, and follow your Arena rank from the desktop.

Questions
Spoken coaching can read Arena's Player.log with Detailed Logs enabled. Autoplay also needs the platform bridge to submit actions. Setup & Repair checks the connection.
The outlook is a heuristic board assessment, not win odds. Paths show modeled continuations under stated assumptions, not future draws or unknown opponent spells. Open Forecast assumptions in Coach for the limits; a green leading line is not a promise of winning.
Coaching and generated commentary use our hosted model service. Chatterbox speech is hosted too; Kokoro speech runs locally. You can choose the speech provider in Speech & voices.
Model requests send the game context needed for coaching or commentary to our service. Hosted Chatterbox also receives the text to speak. Local Kokoro speech stays on your computer.
By default, the app shares redacted finished-match records to help improve Coach. Use Tools → Share Match Logs to Improve the Coach to turn sharing off.
