Market intelligence for MLB The Show Diamond Dynasty
DiamondOps turns the opaque Diamond Dynasty card market into something you can actually read. Difficulty-aware OpScore ratings tell you how a card really plays on Legend, not just its headline overall. Flip opportunities are ranked by profit after the 10% market tax. And your collection is valued in real time, with alerts for the best times to buy and sell.
It's free to browse the market, search every card, and check OpScore rankings — no account required. Built by a player who kept wishing these tools existed, DiamondOps is meant to sit alongside the sites you already use and do the things they don't.
