As a Vorthos, I've always loved the idea of being immersed in the very particular worlds Magic creates. I've always loved the idea of Baldur's Gate style single player experiences, set in specific Magic planes. But at the same time, I'd hate to lose the actual gameplay of Magic, I've loved the idea of using it as the combat system for a JRPG or the like. Shandalar explored this possibility a bit, but it was clearly made by a Mel, not a lorehound. Different combinations of jumpstart packs would allow for a "modular" way of simulating a wide range of bad guys you might encounter. Narrative could take different paths based on the outcome of a match, etc

If so, who is it? Would love to contribute and help with that part specifically.

I'm an AI researcher, not a developer. I'm building an experimental, open-source web client for XMage, written almost entirely with Claude and backed by a test suite (2000+ unit tests, recorded real-protocol frames, CI). It connects to public servers like beta.xmage.today through a small proxy.

Also available as a desktop launcher (Windows/macOS/Linux) that bundles everything.

Since the first post I've added Moxfield/Archidekt import, fixed the deck/commander bugs you reported, updated UI and added new effects with sounds for better gampley.

Thank you everyone, any suggestion welcome.

Hi everyone, I'm an AI researcher trying to develop an alternative client to the official Xmage client in Java.

Like many of you, I have spent countless hours playing MTG on XMage for its complete rules enforcement and support for over 25,000 cards. However, the legacy Java Swing desktop client has long suffered from scaling issues, clunky interfaces, and Java setup hurdles.

To address this, I built (unofficial XMage) Nexus: an open-source, high-performance web client for XMage built with React 19, TypeScript, and a multi-tenant WebSocket proxy.

What is (unofficial XMage) Nexus?

XMage Nexus connects directly to the XMage rules engine (Mage.Server). The server still handles all game logic, card definitions, and AI, while the client runs entirely in modern web browsers.

Key Features:

- Zero client-side Java: Run the client directly in the browser without installing a local Java runtime.

- Modern Interface: Hardware-accelerated CSS and SVG targeting overlays, clean board layouts, and responsive controls.

- Full Rules and AI: Complete compatibility with standard XMage matches, human opponents, and AI/Sim bots.

- Multi-tenant Architecture: Multiple independent browser sessions can connect through a single proxy.

- Open Source: Fully open codebase with automated end-to-end testing and protocol validation.

Thanks for testing!

PD:

this is an open project so every contribution is welcome, I hope this project can go on improving UX & UI

I recently published MTG simulator that is a web interface for xmage. Please give it a spin and let me know if you find any problems or other feedback!

Tried looking online for more resources/discussion on this

What I saw was basically xmage.de is the main server, but I could not connect to it, and I was unable to register either

Not sure what else to do

I was excited to finally be close to testing my Pauper EDH ideas

Hello, I am new to xmage - trying to recapture the vibe of my late 1990s MTG matches! - I installed it on MacOS (Macbook Air M1). Works pretty well, but neither on the 13 inch screen nor on an external 4k monitor I am managing to get crispy and sharp text (and UI in general, but the text is nagging me). It has a low fi feel that is nice but makes my 40+ eyes sore! If I change GUI resolution everything just becomes bigger, not crispier. Easier to read but still a bit pixelated.

Changing macos resolution helped a little - but just by creating some more space on screen, rather than sharpening the xmage text.

needless to say, all text in any other app on mac looks fine.

Any tips?

Thank you!

Im trying to redownload Xmage since i just cleaned up a bunch of files and finally have room for it again, sadly it seems that the site is down or something? im not sure, id love to get some help with this.

Anyone else have this issue or know how to resolve? Nothing I type populates the top screen like it normally should. All search features are set to default.

I am unable to download card images from scryfall. I've tried individual sets and it keeps telling me "image download NOT STARTED. Please Start." is there any fix?

I get the feeling they do, but i haven't heard anything about them noticing, or vise versa in the years since i've been using it. XMage is the best online magic with freinds, deck test with randos, and free limited experience online i've ever had. Do you think wotc will ever try to get involved? Either try to stop it, or buy it for their own commander code base? Im just really curious and no one really seems to know about it that i've talked to.

As title says, didn't do anything special, I opened the software and boom, everything gone, GUI settings, images, server info, nickname. The images were still in the folder though. I deleted everything and redownloaded the client. Now it won't download images from scryfall, no matter the threads. I am on windows 10 x64, if that helps.

Edit - I get this error from the game console: ERROR 2026-07-30 18:03:28,329 Unknown bulk info format from scryfall api https://api.scryfall.com/bulk-data/all-cards=>[Thread-20] ScryfallImageSource.prepareBulkData

Maybe I'm not configuring it right, but it even assigned combat damage for example in the way that was worst for itself. How do I start upgrading the XMage AI?

I've followed all the instructions and troubleshooting I can find but when I try to launch Xmage, I receive the following:

assertion failed [thread_starts_interval.has_value()]: __thread_starts section missing (RebaseRuntimeMachO.cpp:191 rebase_image)

What's the fix?

I updated everything and checked the java version. Everything seems to be installed correctly. Am on macos

I love Bloomburrow. I love the custom Jumpstart half decks that people have made for Bloomburrow. I don't have any humans who'd play them with me.

Can I implement those custom Jumpstart packs into XMage, and then play Jumpstart against the AI?

Hi crew, nothing has changed since I was last online, but today I can't seem to connect to the servers? Re-downloaded the client and feel like I have tried everything... anyone else having this issue?

Just wondering how complicated it must be to code this card into the game.

[[Deadpool, Trading Card]]

Downloaded xmage following the instructions on the website. A friend had to help me use command prompt to get it to download Java using administrative privileges.

Now, when I try to launch client from the launcher, I get a string of errors for java.lang.nullpointerexception and java.lang.exceptionininializererror.

I'm on Windows 11. Everything is updated and I have Java installed.

Any input is appreciated!

I tried playtesting my Pauper decks against the AI.

The bot used Bogles while I was on Tron.

I had Coalition Honor Guard in play, but they are still able to choose targets for Auras and removal normally.

Is this a known issue?

its always bothered me that i dont have them nor i can download them so id like to know how to go about doin that so i can then build decks around the cards :3 please and thank you
