The Gamegenic Sidekick PRO 100+ XL Convertible Black is a high‑end deck box developed for the Magic: The Gathering Commander format and other 100‑card decks that require secure, organized storage. It holds up to 100 double‑sleeved cards in extra thick inner sleeves, or 100 regular double‑sleeved cards with additional room for token cards, making it ideal for Commander / EDH, Brawl and other singleton formats.

A key feature of the sidekick pro 100+ xl black is the integrated Slide Card Case positioned at the front of the box, which displays your commander or top card with added UV protection so the deck is instantly identifiable without opening the lid. This Slide Card Case is detachable and can be used on the table during games, serving as a stand‑alone commander or leader display. Beneath the main card compartment, an integrated drawer provides extra space for tokens, dice and accessories, turning the deck box into a complete solution for tournament and casual play.

The Sidekick PRO 100+ XL uses Gamegenic’s convertible system: the fully removable cover clips onto the bottom while playing, saving space on the table and offering flexible display angles for the deck and Slide Card Case. Cards are stored horizontally (sideloading), which many players prefer for drawing and shuffling, and powerful magnets provide a precise, secure closure during transport. The outer material is made from Armorfyber with a premium feel, while the interior uses a soft microfiber lining to protect sleeves and card edges.
