mage VS forge

Yeah, that surprised me too, given that https://github.com/magefree/mage is open source and pretty actively developed.

The project you want is http://xmage.today/

All cards available, and full rules engine.

My guess is that fully modeling MtG's rules in Datalog would take a lot more work, because MtG's rules are a lot more complex. Looking through the source for one of the freely-available game engines like https://github.com/magefree/mage would probably be more informative, though.

There's a draft every day, with events at different starting times to accommodate players from around the world, plus asynchronous side events including Rich Draft, Team Sealed, and Rotisserie Draft. We play on XMage which has full rules enforcement like MTGO but is 100% free software.

If you can tolerate some of its shortcomings, you can draft against bots on Xmage.

https://github.com/magefree/mage/issues is a more reliable place to report - this might not be a trivial fix

Update: My problem happened because the launcher had reverted to the non-beta xmage home address on its own. You probably have the same problem. You need to go to settings, set branch to custom, and the xmage home address to http://xmage.today/

Real life example: The open source implementation of MTG card game multiplayer

If you like Magic The Gathering card playing game, avoid Forge (Desktop + Android) because it is open source (made in Java) and it has all the cards, gameplays, you can build your deck or choose from a huge list of ready-made ones and play against the AI and online up to 4 players in the same game I believe.

Please read into it if you care to criticize.

If you did want to see something like this, the MTG program Forge(https://github.com/Card-Forge/forge) has a command line tool included that allows you to pit ais against each other using different decks. It isnt terribly hard to setup, and im sure the discord server can help out as well.

The last thing I recommend to you is to download a piece of third-party software called CardForge. It lets you play Magic on your phone or your computer. It's a little clunky, but it includes all 26,000 cards, for free, and it's free, meaning you can get your hands on (IE import) other people's decks and try them out. For instance, mine. ;) You can even compare it to yours! I don't mean to be dismissive, but this will be the easiest way for you to find out what we're all talking about. I didn't find this app until... I dunno, a little before the pandemic started? But it completely changed my understanding of how to play the game... or, more accurately, let me try out decks that win at very high levels and figure out why they do. Now you can too! =)

Y'all could check out the adventure mode on Forge, pretty similar vibe!

That said, if you really want better legitimate options, go play MTG Forge! It supports every major format under the sun, has 2 dedicated RPG modes and the ability to run against gauntlets of decks. You could probably import all the Duels 2015 decks there, find a Duels 2015-esque skin, and enjoy the meta of that game that way.
