Hi @pdalfarr,
Thank you for your message! It sounds like the feature you’re requesting is an ability editor.
You can find more information about this feature here. However, please note that this feature is still in development. Once released, players will be able to create custom content.
Currently, we pull data from marvelcdb.com, which provides every card with a unique card ID and JSON data for parsing, helping to streamline our work. If there is a similar website for custom content, we will consider adding it.
Regarding the “rules enforcement system” you mentioned, if it is similar to the challenge mode, then yes, it is script-based. However, it still requires the engine to support it.
Thank you again for your input!
