The most valuable cards and sets, and how set values stack up. In Union Arena the wealth sits in the promos and the sets tied to the most popular anime, plus the scarcer early printings.
How to read an anime-hype market
Union Arena value is driven by anime popularity and momentum more than by scarcity, which makes it fast and volatile. A set can surge when its series trends and give it back when attention moves on, and Bandai reprints readily. That makes set-level tracking and treating steep gains as momentum, not permanence, essential. The methodology explains how the signals account for it.
