MOXXUSFRIENDS & PLAYTESTERSYOUR DECK. YOUR PEOPLE. YOUR TABLE.
An independent card-game playtesting table for friends.
Start with two people and let the AI fill the other seats.
The current download is a portable ZIP. Follow the steps below to extract and launch it. A guided Moxxus Setup installer is being tested; it is not available yet.
Already playing? Keep your existing installation and saved decks. You do not need to reinstall while the installer is being prepared.
Install once. Pick an open table. No networking setup needed.
The Windows download is hosted on Cloudflare. Artwork downloads separately from the publisher’s computer.
The public-online build is being validated. Wait for the verified download to become available.
Right-click the ZIP and choose Extract All. Extract into a short folder such as C:\Games\Moxxus; deeply nested folders can exceed Windows’ path-length limit. Keep its folders together. Open CommanderLab.exe from the extracted folder, not from inside the ZIP.
This early build is unsigned. If SmartScreen appears, verify you downloaded the file linked here before choosing More info → Run anyway. Do not disable Windows security.
Open My Decks and import your Commander deck file. Artwork downloads automatically as needed. In Settings → Updates / art, choose Standard or Enhanced 4×. You do not need to download the full catalog.
Open Join or Create Game. Enter your name and join an available table from the game list. Choose your saved deck and click Load deck into my seat.
Check the commander previews, then each human clicks Ready up. The game starts automatically when everyone is ready. The coin-flip winner starts; choose whether to keep or mulligan your opening hand. Two AI players fill the other seats. First startup can take several minutes while the rules engine loads; keep the app open.
Create a table on the shared online game server. Your computer does not run the server.
Follow the Join a game tab to install the current Windows build and save your deck. No access key is needed.
Open Join or Create Game. Enter your name and choose Host game. Your table appears in the lobby list. Open seats are filled by AI until friends join; with two humans, the remaining two seats are AI.
Only one active table is supported during this testing period.
Ask your friend to select your table in the lobby list. Each human chooses a saved deck and clicks Load deck into my seat. The host can select a saved deck for each AI and upload it to that AI seat. Verify the confirmed commander and card count for all four seats. Membership credentials are handled privately by the app.
When all decks are loaded, each human clicks Ready up. The game starts automatically and shows loading progress. The coin-flip winner starts; opening-hand choices remain yours. During testing, the owner can close the entire game from the lobby or Settings; this disconnects everyone.
The online game server and artwork service are separate. The publisher’s computer serves downloads and must remain online for artwork that is not cached yet.
The Mac app and installation instructions are not ready yet. Please do not download the Windows ZIP for a Mac. We will add a separate Mac download and setup guide after testing.
Planned: cube playtesting, drafting into one-on-one matches, and Two-Headed Giant. These modes are not available yet.
A QUICK HAND
Install this updater-enabled build once. It checks at startup and every 30 minutes, downloads signed releases in the background, and offers a restart outside a match. Your decks, settings and cached artwork stay intact. Automatic downloads can be disabled in Settings.
Retry the download from this page. If it still fails, ask the host to check the download service. Tailscale is not required. Never use a replacement download with an unverified source.
Use Join or Create Game and the current build. Check whether the host has an open table. A message about an incompatible version means the app needs an update.
If the app shows a pending request, use Retry pending request with the same details. Do not repeatedly create new rooms or abandon a pending request unless you intend to leave that attempt.
For two people and two bots, host a table and have your friend join it. Both humans upload decks; the two remaining seats are AI. The host can choose each AI’s saved deck. Check each seat’s commander and card count, then each human clicks Ready up. The game starts automatically; watch the loading stage.
Reopen Join or Create Game and use Reconnect reserved seat. The app saves your private membership on this computer. Do not forget it or create a new room. Decision and reconnect timers are disabled by default. Leaving saves your seat on this device; reopening your saved room restores it. A stopped server process cannot restore the old match.
No. Standard is the default, and only artwork needed by decks and visible cards downloads automatically. Enhanced 4× is optional. Settings shows signed catalog sizes and estimated extra disk space before an optional full download. Cached cards work offline; missing artwork temporarily uses text cards.
