Ultimate Guard Sidewinder 100+ Xenoskin Card Sleeves: Magic The Gathering - Duskmourn House of Dusk

Duskmourn Lives in Your Deck Box

The Ultimate Guard Sidewinder 100+ Xenoskin in the Magic: The Gathering – Duskmourn: House of Horror Niko art isn't just storage — it's a statement. Built from Xenoskin, Ultimate Guard's proprietary soft-touch synthetic material, this deck box carries the premium feel of a product made for players who care as much about their setup as their strategy. The haunted-house aesthetic of Duskmourn translates beautifully onto the Xenoskin surface, and the Sidewinder's side-loading design keeps that artwork front and centre every time it hits the table.

Capacity Built for Real Decks

The Sidewinder 100+ is engineered to hold 100 double-sleeved cards — the gold standard for Commander and competitive formats where inner sleeve plus outer sleeve is non-negotiable. If you're running single sleeves, it expands to accommodate 120 cards, giving you comfortable fit without a fight. This is one of the few deck boxes where double-sleeve compatibility isn't an afterthought — it's the design target. Commander players building around Niko or any 100-card list will find this fits their deck precisely as intended.

Sidewinder Design & Closure

The defining feature of the Sidewinder line is its side-loading thumb notch, which lets you draw cards out laterally rather than fishing from the top. For players who access their deck constantly during a game, that ergonomic difference is immediately noticeable. The magnetic closure provides a firm, positive snap — secure enough to travel with confidence, easy enough to open one-handed mid-session. The interior is smooth and card-friendly, and the Xenoskin exterior resists scuffs and minor moisture far better than standard polypropylene boxes.

Who This Box Is For

This is the deck box for the player who double-sleeves their Commander build and wants their carry to match the effort they've put into the list. The Duskmourn Niko art makes it a natural companion for anyone running a House of Horror themed deck, or simply a collector drawn to the set's striking visual identity. It's also a strong gift pick for any Magic player — Xenoskin boxes from Ultimate Guard are a clear step up from basic plastic, and the limited set art makes it feel intentional rather than generic.
