Union Arena is a crossover trading card game featuring many anime series, such as Jujutsu Kaisen, Hunter x Hunter and Code Geass. Each deck is built from a single series, and you place cards in an energy line to pay for stronger characters in your front line. Action points limit how many characters you can use each turn, and the raid mechanic lets you upgrade a character mid game. You win by stripping all seven Life cards from your opponent.
