Union Arena Umamusume: Pretty Derby Booster Pack

Union Arena is Bandai's card game where each anime and game title gets its own set built on the same rules, so decks from different series can face each other across the table. Here the focus is Umamusume: Pretty Derby, the story of the horse girls who train, race and live up to their namesakes from real racecourses. The cards are in English and the pack comes sealed from the manufacturer. The image is Bandai's preview image of the set; the packaging has not been shown yet.

The series works both on its own and together with the starter deck released for the same title.

A single sealed booster pack. It is the cheapest way to open the set and get a feel for it before you buy larger formats. If you want the steadiest route to the rare cards, a full display gives a better price per pack, but single packs are right when you want to try it out, fill gaps or give a small gift.

This item has not been released yet. The release is announced for 12 February 2027, and we ship as soon as the item is in our hands. The price is preliminary and may be adjusted up or down until release. The artwork cannot be chosen: if the edition is printed with several pack designs, the pack you receive may differ from the one in the image.
