The new card is out, and while the structure is familiar there are enough changes to be worth an hour of your attention before league night.
The sections have not moved. Consecutive runs, pungs and kongs, quints, winds and dragons, the number families, the flower hands — all still in the same order, which means your filtering routine still works.
The changes are in the lines. A number of limited lines have been retired and replaced, and the values on several hands have been nudged up or down by five points. Nothing dramatic, but if you have been playing last year's card on muscle memory, the five-pointers are where you will get caught.
Flower hands got slightly cheaper. Two of the flower lines that were worth 50 last year now sit at 45. If flowers were your reliable fallback, check whether that is still true.
Joker notation is worth re-reading. Every year a handful of hands change their joker permissions, and it is never the ones you expect. Read the notation on the three or four hands you play most often before you sit down.
The practical version: the card is a catalogue, not a test. Spend an hour with a pencil, mark the hands you like, and the season will take care of itself.
