As the MLB season edges past the All-Star break, it's customary for teams to take stock of their roster and their position in the standings to decide if they will be buyers or sellers at the approaching trade deadline. Similarly, it might also be an ideal time for MLB The Show 25 players to take stock themselves of the Diamond Dynasty Live Series cards of All-Star players to decide which cards are worth buying and selling at this critical juncture.
