Ultra PRO: 100+ Deck Box - March of the Machine (Kasla, the Broken Halo)

Kasla, the Broken Halo Watches Over Your Build

Martina Fačková's striking artwork of Kasla, the Broken Halo wraps this Ultra PRO 100+ Deck Box in full-colour art straight from Magic: The Gathering's March of the Machine set. It's the kind of box that turns heads on the table before a game even starts — and underneath the art, it delivers the reliable card protection you'd expect from a deck you've actually put time into building.

Built for Double-Sleeved Decks

This box holds up to 100 standard-size cards in double sleeves — which means your Commander deck, your Pioneer build, or your prized Modern list fits comfortably with full inner and outer sleeve protection. That's a meaningful spec. Many art boxes at this price point cap out at single-sleeved capacity, so the confirmed double-sleeve compatibility here is worth noting. A deck divider is included, letting you separate your main deck from your sideboard or tokens without needing a second box.

Rigid Polypropylene Construction with Self-Locking Lid

The box is made from archival-safe, non-PVC rigid polypropylene — a material that won't off-gas or degrade the card sleeves over time, which matters if you're storing anything valuable. The self-locking lid snaps securely shut for transport and opens cleanly for access during play. It's a practical mechanism: your cards stay put in a bag, and you're not fumbling with magnets or straps when you need to make a quick sideboard swap.

A Great Entry Point or Display Piece

Ultra PRO occupies the accessible end of the deck box market — solid construction, officially licensed art, and a price that doesn't require a second thought. This March of the Machine box works well as daily carry for a competitive player who wants art they love on the table, a gift for a Magic player with a favourite card or set, or part of a collection of art boxes from a set you're invested in. The Kasla artwork by Fačková is distinctive enough that it'll draw comment from players who know the set.
