What drives Union Arena prices

As with any trading card game, Union Arena value concentrates in scarcity and demand: early or short-printed sets, chase rarities, and cards that matter for play or collecting. The scarce cards in a handful of sets carry most of the value, while the long tail stays inexpensive. The Union Arena market is up about 32% over the last 90 days, with roughly 47% of cards rising, so the moves are rarely broad. Track value at the set level and treat the loudest percentage swings on brand-new sets as noise until they age.
