Union Arena
Union Arena is Bandai's multi-franchise trading card game, launched in Japan in 2023. Its big draw is that some of the most popular anime and games of the moment share one game system.
Unlike a single-series TCG, Union Arena lets you build a deck from your favorite series and play it against any other: Bleach, Hunter x Hunter, Attack on Titan, Solo Leveling, One Punch Man, Chainsaw Man, Sakamoto Days or Kaiju No. 8, among many others.
How does Union Arena work?
- Five colors (red, blue, green, purple and yellow): each series is tied to one or more of them.
- Parallels: many cards also come in star (★) versions, and the SR★★★ versions are among the most wanted pulls.
- Rarities: Common (C), Uncommon (U), Rare (R) and Super Rare (SR), plus cards with foil-stamped signatures from the anime's Japanese voice actors.
- Each pack has 8 cards; most booster boxes have 16 packs (128 cards).
Why the Japanese edition?
- It's the original Bandai Japan edition, and new series come out in Japan first.
- The signed cards carry the signatures of the Japanese voice actors.
At Metamorph Center you'll find Japanese Union Arena booster boxes from series like Bleach, Solo Leveling, Chainsaw Man and Re:Zero, all original and factory sealed. Ships from Spain. 24 - 72 h within Spain, 3 - 8 business days to the rest of Europe. Questions? Ask us in the chat.
