What makes UA59ST different?

The biggest difference is the Promotion R Pack.

Unlike a basic starter deck that only contains a fixed 50-card list, UA59ST includes a separate 4-card promotional pack with new Rare cards that are exclusive to this product.

Those cards also use different attributes from the main deck, giving players a direct path to experimenting with additional Uma Musume deck configurations after learning the starter strategy.

Connection to UA59BT

UA59ST launches on the same day as the Uma Musume Pretty Derby Booster Pack [UA59BT].

Some cards in the Starter Deck use different artwork from cards appearing in the booster, while UA59BT expands the title with a much larger card pool and parallel lineup.
