Diamond Dynasty is a baseball card collector / video game enthusiasts' dream! It's a mode within MLB The Show 19 that allows you to build a fantasy team using virtual baseball cards. These virtual cards are either earned by playing or purchased with an in-game currency known as Stubs (more on that later). The virtual cards you collect are used when you play the game, so typically the better, rarer, more expensive cards give you the best opportunity to win when playing the computer or against others online. With weekly gameplay and content upgrades made throughout the year, Diamond Dynasty is definitely the 'must play' mode within MLB The Show 19.
