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

A Deck Case Built for the Avatar

The Ultimate Guard Sidewinder 100+ in Avatar: The Last Airbender White brings together one of the hobby's most trusted deck boxes with artwork from one of the most beloved animated series ever made. This isn't just a pretty shell — the Sidewinder line is a staple in organized play for a reason. The Xenoskin exterior has a refined matte texture that resists fingerprints, holds up to daily handling, and gives the box a premium feel that plain polypropylene simply can't match.

Capacity That Handles Your Full Build

The 100+ designation means real-world capacity for real-world decks. The Sidewinder 100+ Xenoskin is built to hold 100 double-sleeved cards — meaning your deck in inner sleeves plus standard outer sleeves — or up to 120 single-sleeved cards. This is the capacity sweet spot for Commander players and 100-card formats, and the double-sleeve compatibility is confirmed, making it a serious choice for players who protect their investments at every layer.

Sidewinder Mechanism & Build Quality

The defining feature of the Sidewinder series is its side-loading design — the lid swings open from the side rather than the top, letting you fan your deck naturally without any awkward reorientation. The magnetic closure delivers a clean, positive snap every time. No loose flaps, no fumbling. The lid stays securely open when you need it to. A thumb notch on the front makes drawing cards smooth and effortless. This is a box you can confidently pull from a bag, set on a table, and crack open in one motion.

The Xenoskin Difference

Xenoskin is Ultimate Guard's proprietary soft-touch material — a leatherette-style finish that sits over a rigid inner shell. It's durable, it's tactile, and it ages well. The Avatar: The Last Airbender White colourway is clean and bold, making it a standout on any game table. If you're a fan of the series or just appreciate a deck box that looks as good as it performs, the artwork here earns its place.

Who This Box Is For

This is the deck box for the Commander player who double-sleeves their staples, the Magic player heading to Friday Night Magic who wants something reliable and distinctive, or the Avatar fan looking for gear that reflects their taste. Ultimate Guard's build standards are a step above the entry tier — this is a box you buy once and carry for years. It also makes a genuinely great gift for any player in your life who takes their deck seriously.
