★ The quick answer Why choose Ultimate Guard? Ultimate Guard makes some of the most-loved deck boxes in the hobby. The Boulder is a rigid, pocket-sized case for 100 double-sleeved cards; the Sidewinder adds a magnetic closure and microfiber lining; Squaroes turn your deck box into a collectible; and Katana sleeves are acid-free and PVC-free. Start with a Boulder, then upgrade as your collection grows. |
Ultimate Guard was created in 2011 by the heo Group, founded in 1996 by three friends in the small village of Herxheim, Germany. The brand broke through with its Flip’n’Tray deck box, which introduced its signature Xenoskin material, and in 2024 it signed an official license for Magic: The Gathering accessories. Below, we walk through every Ultimate Guard family we stock at Saga, with the question each one answers best. Pair any of them with our MTG, Pokémon, One Piece or Lorcana decks.
