Union Arena

The number of stars beside the rarity is what moves the price.

The number runs from the set code to the series to the card, as in UE01BT/BLK-1-001. We read that whole string.

The rarity row holds Common, Uncommon, Rare, Super Rare, Action Point, Union Rare and Special.

A star after the rarity is a separate printing with its own price, so Rare 1-Star and Rare are two different cards to a buyer.

The kind row holds Character, Event, Site, Action Point and Marker.
