Diamond Dynasty Lineup Optimizer · iPhone & iPad · iOS 17+
Stop guessing which cards should start. RosterOps syncs your Diamond Dynasty card collection and builds the optimal lineup based on difficulty ratings, quirk weighting, positional composites, and platoon matchups — so every lineup decision is backed by data.
Sync your Diamond Dynasty card binder via the DiamondOps Chrome Extension. RosterOps only considers cards you actually own.
Card ratings aren't equal across difficulties. RosterOps applies difficulty-specific weights so your lineup is optimized for the mode you're playing.
Quirks have real impact on performance. RosterOps weights lineup decisions by quirk compatibility for each batting position.
Build a lineup that wins on both sides of the ball. Defensive ratings are factored into every positional recommendation.
RosterOps doesn't just tell you who starts — it tells you why each card is recommended for each spot in the order.
Once your collection is synced, no internet connection is required. Your lineup data stays on your device.
