Ultimate Guard Boulder Deck Case 100+ Eclipsed Changelings

Built Like Its Name Suggests

The Ultimate Guard Boulder Deck Case earns its name. This is a rigid, no-nonsense deck box engineered for players who want their cards protected without compromise. The Boulder's thick-walled construction resists the kind of flex and crush that cheaper plastic cases fail at — whether it's rattling around in a backpack between FNM and work or sitting at the bottom of an overstuffed game bag. The Eclipsed Changelings colourway brings a striking visual identity to a box that already has the structural credentials to back it up.

Capacity & Sleeve Compatibility

The Boulder 100+ is built for real-world deck sizes — not the theoretical 60-card minimum. It holds up to 100 double-sleeved cards or 120 single-sleeved cards in Ultimate Guard sleeves. That double-sleeve capacity is the headline: this is a box Commander players and spike-level 60-card grinders alike can rely on without squeezing or stacking. Side-loader access means you're not digging cards out from the top.

Closure & Construction

The Boulder uses a secure snap closure that holds tight in transit but opens cleanly during play. The rigid polypropylene shell doesn't flex under pressure — there's no give in the walls, which means the cards inside aren't absorbing lateral force when something heavy lands on the box. The design is straightforward and functional: no moving parts to break, no magnets to lose strength over time, just a well-engineered shell with a reliable lid.

Who Should Grab This Box

The Boulder 100+ is the go-to for Commander players who double-sleeve their 100-card decks and want protection they can trust session after session. It's equally solid for competitive players running double-sleeved Standard or Modern lists who demand durability from their daily carry. Ultimate Guard has built a reputation for exactly this kind of no-frills premium construction — this is a box you buy once and don't think about again.
