More Cards, More Kirito, More Ways to Win
The second booster wave for the Union Arena Trading Card Game's Sword Art Online set dives deeper into the worlds of Aincrad, Alfheim, and beyond. Whether you're chasing alternate art finishes, rounding out a competitive deck, or cracking packs for the thrill of the pull, this booster box delivers 16 packs of SAO-themed cards drawn from one of the most beloved anime franchises in the world. Each pack adds new tools to your Union Arena roster — new characters, new abilities, and new synergies to explore across the game's energy-driven combat system.
What's in the Box
Each booster box contains 16 booster packs. Union Arena packs follow the standard set structure with a mix of rarities — commons, rares, super rares, and the foil and alternate art variants that make cracking packs genuinely exciting. The Sword Art Online Vol. 2 set expands on the foundation laid by the first wave, introducing additional characters and cards from the SAO universe alongside new energy-cost options and effect combinations. This is a sealed booster box, meaning cards are randomised across packs — contents will vary.
Who Should Grab This
Union Arena players already running an SAO deck will find Vol. 2 essential for deepening their card pool and hunting the rarest pulls from the set. Fans of the Sword Art Online anime who want to collect cards featuring their favourite characters will find plenty to chase here. New players considering Union Arena should note that booster boxes work best alongside a starter deck — the starter provides the core engine, while booster packs expand and refine it. This box also makes a strong gift for any SAO fan who's already in the game.
