The Gamegenic Sidekick PRO 100+ XL Convertible Blue is a premium deck box engineered specifically for Commander and other 100‑card formats that require secure, organized storage. Designed to hold up to 100 double‑sleeved cards in extra thick inner sleeves, it also fits 100 regular double‑sleeved cards with additional room for token cards, making it ideal for Commander / EDH, Brawl or other singleton decks.

A standout feature of the sidekick pro 100+ xl blue is the integrated Slide Card Case, which sits in a dedicated front window to display your commander or top card with extra UV protection. This allows the stored deck to be identified instantly on a shelf or in a bag without opening the box, and the Slide Card Case can be detached and used on the table during gameplay. Beneath the main compartment, an integrated drawer offers extra storage for tokens, dice, counters or small accessories so everything needed for a game session stays in a single, compact accessory.

The Sidekick PRO 100+ XL Convertible Blue uses Gamegenic’s convertible system, meaning the fully removable cover attaches magnetically to the bottom during play to save space on the gaming table. Cards are stored horizontally (sideloading), which many players find more comfortable for drawing and shuffling during matches. Strong magnets keep the box securely closed during transport, while the high‑quality outer material and microfiber‑style interior protect sleeves and card edges from wear.
