Quirk Stack Finder

Quirks are the hidden modifiers that make a card better in specific situations — against a certain handedness, in a certain count, on the bases, or on the mound. Individually they nudge an outcome; stacked across a lineup, the right quirks compound into a real, repeatable edge.

The Quirk Stack Finder surfaces which quirk combinations are available at each position, so you can build a roster whose quirks actually reinforce each other rather than collecting cards one at a time and hoping they fit. Filter by position and quirk type to see the stacks worth building around, then cross-reference the OpScore rankings to make sure the cards carrying those quirks also play well at your difficulty.
