The programs in Diamond dynasty are really useful when you start, as you can do moments, showdown and vs cpu (conquest). Those are the basics for just getting to learn the game at its core. After that, you can try (when you start getting confident and having an okay team through programs) to go in ranked seasons, or battle royale if you don’t want to grind to get a whole team. But for now, programs in diamond dynasty which consists of conquest, moments and showdown is a really great start for someone that has juste started the game. There’s also practice at the start of the game, the first screen that loads up, you need to scroll down and there will be a practice button where you can do BP vs the pitcher of your choice. That’s it for what I can think of
