This reminds me of the good old Cockatrice days. When I moved to Sweden myself and some friends in the home country digitalized our MTG decks in cockatrice so we could play over the internet.
the software didn't really have any rules, you basically had/have a "hand", some stages on a table-top and markers/counters that you can create on top or in relation to cards and "dice". players still enforce the rules so to speak, so you're more or less forced to have voice comms or chat to the side.
Your game looks pretty advanced and cool!
