Forge is an open-source, unofficial rules engine for Magic: The Gathering built in Java, letting players play against AI opponents across many formats. It includes single-player Adventure and Quest modes and runs on desktop platforms and Android.
Use cases

- mtg adventure mode like shandalar
- open source magic the gathering rules engine
- play mtg on android without internet
- build custom cards for a mtg engine
When to choose
- you want to play MTG solo against AI in formats like draft, sealed, or commander
- you want a free cross-platform MTG client on Windows, Mac, Linux, or Android
- you want to explore an overworld adventure mode with card collection
