Sidewinder Secrets of Strixhaven Force of Will 100+ Deck Box

Strixhaven Spellcraft Meets Ultimate Guard Engineering

The Sidewinder 100+ Deck Box from Ultimate Guard brings the mystical energy of Secrets of Strixhaven to one of the most trusted deck protection formats in the hobby. The Sidewinder's signature side-loading design keeps your cards secure without the awkward fumble of a top-opening box — slide your deck in, snap it shut, and you're ready to game. This isn't a box you'll outgrow after a season; it's built to the standard that serious players expect from Ultimate Guard.

Capacity & Sleeve Compatibility

Rated for 100+ cards, the Sidewinder 100+ comfortably accommodates a full Commander deck or any 100-card format in standard sleeves. The generous internal volume handles single-sleeved cards with ease, and the 100+ sizing is designed with double-sleeved compatibility in mind — critical for players who run both inner and outer sleeves on their most valuable builds. Whether you're running a tight 60-card Standard deck with room to breathe or a fully sleeved Commander build, this box has the space.

Build Quality & Closure

The Sidewinder uses Ultimate Guard's well-regarded magnetic closure system, delivering a satisfying, secure snap every time. The rigid polypropylene shell resists the everyday punishment of bag carry, tournament tables, and stack storage. The side-loading entry means cards slide in horizontally — a design that protects corner integrity during loading and gives fast, clean access during deck checks or mid-session sideboard swaps.

Hive System Compatible

One of the Sidewinder's strongest features for the organized player: it's designed to slot directly into Ultimate Guard's Omnihive, Superhive, and Smarthive mass storage systems. If you're building out a collection storage setup at home, your Sidewinder deck boxes become modular components of a larger system — no more stacking mismatched boxes. It's ecosystem thinking that rewards players who are serious about keeping their collection organized.

Who This Box Is For

The Secrets of Strixhaven art treatment makes this an obvious pick for fans of the MTG academic setting — but it earns its place in any bag on the strength of its build alone. Competitive players who need a reliable daily-carry box, Commander enthusiasts protecting a double-sleeved build, and collectors who want their deck displayed with some personality will all find this Sidewinder punching above its price point. It also makes a genuinely great gift for a player who takes their deck seriously.
