Bandai UNION ARENA Uma Musume Pretty Derby Starter Deck [UA59ST]

Start playing UNION ARENA with the Uma Musume Pretty Derby Starter Deck [UA59ST], a ready-to-play Japanese deck from Bandai.

The set includes one pre-constructed 50-card deck, 3 Action Point cards, a character-designed play sheet and an exclusive Promotion R Pack.

The Promotion R Pack contains 4 new Rare cards available only in this Starter Deck, with one copy of each card included. These cards use two attributes different from the main 50-card deck, giving players additional options for expanding their Uma Musume strategy.

The included play sheet features Special Week, Grass Wonder, El Condor Pasa, Seiun Sky and King Halo, making the product useful both as an entry deck and as a character-focused collectible item.

Official Japan confirms all of these points.

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.

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.
