Union Arena

Union Arena is Bandai's crossover card game: one set of rules, and a long list of anime and game licences printed into it. Jujutsu Kaisen, Hunter x Hunter, Code Geass, Bleach, Demon Slayer and many more each get their own cards, and a deck is built from a single licence.

The board is the interesting part. Your characters sit in one of two rows: the Front Line, where they can attack and be attacked, or the Energy Line, where they generate the action points that pay for everything. Moving a character between those roles is the central decision of every turn.

• Your life is a stack of cards. When you take damage, cards leave it, and many of them have trigger icons that fire on the way out.
• Action Points (AP) are your resource, and your own characters produce them.
• Raid lets you play a stronger version of a character on top of one already in play, which is the game's big swing turn.
• Games are quick and aggressive, and the licences do not mix, so your favourite show is a deck rather than a splash.

• Character: a body. Cost in AP, battle power, and an ability. Lives in the front line or the energy line.
• Event and Field cards: one-shot and persistent effects.
• Colour and licence: your deck is built inside one licence, and colours within it gate certain cards.
• Trigger icons: printed on cards, and they matter when the card is revealed from your life stack rather than played from hand.

6. 6

   End

   End-of-turn effects, then pass.

• 50 cards, all from one licence, up to four copies of a card by name.
• Balance cheap characters that can hold the energy line against the expensive ones that win fights.
• Include raid targets and the cards that raid onto them, or your big turns never happen.
• Watch the colour requirements inside your licence: they are the real constraint on a two colour build.

• Standard constructed with a banned and restricted list Bandai maintains.
• Sets are per licence, released in waves, with starter decks alongside boosters.
• Shop level organised play is the main scene, growing into regional events.
• Chase cards are the alternate art and special rarity prints of headline characters.

Union Arena is unusual: it is a crossover product where the stories never actually cross over. Each licence keeps its own cast, its own art and its own deck, and the shared thing is the rules set rather than a plot.

• That is a deliberate design: it means a Jujutsu Kaisen fan and a Hunter x Hunter fan can play each other without either franchise being bent out of shape.
• Card art is taken straight from the anime and manga, which makes a binder page read like a highlight reel.
• Because the rules are shared, learning one licence teaches you all of them.
• Newer licences keep arriving, so the "what is in this game" list is genuinely a moving target.
