That's playing against the computer, right? I'm sure that would be really easy to set up. And honestly they should update the Practice mode with that. For anyone that isn't completely new to the game the practice mode is kind of a joke with those rather weak decks (even on "expert" difficulty) so why not let us pick the deck to play against? Well, I guess the reason is quite simple. They don't gain much out of it and it might need a relatively big UI adjustment. I still hope they will eventually get around to do it. Somehow.

In the meantime the best thing is (like already said) to play a friendly game with someone since you have the feature to share decks. As fate would have it I created a group to find people to play friendly games with. If anyone is interested the invite link can be found in another thread: "Play Friendly Game"-Button
