Great decks win games, but great sideboards win tournaments. So why is it that deck boxes just don't come with sideboard space? Well, now they do. Meet The Big Box, holder of cards and savior of sideboards. With a half-inch of extra width on cheapie card boxes, Stratagem's Big Boxes hold over 90 sleeved cards (or, if you're a little more cavalier with your cards, over 170 unsleeved). That's enough room for your 60-card deck, your 15-card sideboard, and a fancy matching divider to keep them separate, all in one box.
