Ultimate Guard Sidewinder 100+ Deck Case: Avatar The Last Airbender - Blue

Avatar the Last Airbender Meets Tournament-Grade Protection

The Ultimate Guard Sidewinder 100+ in Avatar: The Last Airbender Blue brings together one of the most trusted deck boxes in organized play and iconic artwork from a beloved universe. Built from Ultimate Guard's Xenoskin — a textured, leatherette-like material that resists scratches and feels premium in hand — this isn't a box that sits on a shelf looking pretty. It's engineered to go everywhere your deck does and come back in the same condition it left.

Capacity Built for Real Decks

The Sidewinder 100+ earns its name: it comfortably holds 100 double-sleeved cards or 120 single-sleeved cards in Ultimate Guard sleeves. That makes it Commander-ready out of the box, with room for a full 100-card deck in inner and outer sleeves without forcing the lid. Single-sleeve players running 60-card formats will find extra breathing room — no cramming, no stress on the closure.

The Sidewinder Design: Side-Loading Done Right

What sets the Sidewinder apart from a standard top-loader is its side-loading mechanism — the lid opens laterally, presenting the full deck face-on and making it easy to pull cards cleanly during a game or deck check. The closure uses a magnetic snap with a positive, confident click that holds firmly in a bag without accidentally popping open. The lid stays open during play, and a thumb cutout on the base makes retrieving your deck effortless, even with thicker double-sleeved cards.

Xenoskin Construction

Xenoskin is Ultimate Guard's hallmark exterior — a synthetic material with a soft tactile grip that doesn't attract fingerprints and holds up to the daily abuse of transport, tournament tables, and backpack life. The interior is smooth and snag-free, protecting your sleeves from any roughness that could cause micro-tears over hundreds of in-and-out cycles. This is the build quality that earned Ultimate Guard its reputation among competitive Magic, Lorcana, and Pokemon players.

Who Should Pick This Up

This box is the daily carry for the Commander player who wants their deck protected and their table presence to reflect the fandoms they love. It's equally at home at Friday Night Magic or a weekend tournament as it is on a display shelf. For Avatar fans who take their card game seriously, the Blue colorway ties directly to the Water Tribe aesthetic — meaningful theming, not just a sticker on a generic shell. It also makes a thoughtful gift for a player who has everything except a deck box that actually reflects their personality.
