Your New Favorite Commander Deck Box
Commander remains a favorite format among Magic players. However, unlike playing Standard or Modern, having access to a variety of Commander decks is important. Players often ask “What’s the best method to hold and store multiple EDH decks?”. We believe the BCW Prime X4 XL is the answer to that question.

The Prime X4 XL holds 4 double sleeved, 100 card decks in the four main cells. This lets you have a variety of decks to match against different power expectations, or to supply decks for a standard 4 player Commander game. The removable partitions allow the cells to become large enough to hold double-sized cards, such as Planechase planes or Vanguard character cards.
The case features two removable cups for dice, counters, coins, chips, anything that would be needed for play. I personally use one for dice, and one for glass beads. I pass the trays around and allow other players to borrow dice or tokens if playing with friends, but you should obviously follow your comfort level for this.
The final two cells in the back are extremely versatile. Each of the small cells will hold about 50 double sleeved cards, more if single or unsleeved. From tokens to sideboards, trade fodder to separate decks entirely, the small cells add extra utility for the case.
Not only is the case useful for edh players, but, with the partitions removed, are also useful for storing cubes. The slot for the large token box will hold over 60 double-sleeved cards, acting as a land station for smaller cubes. If you prefer your cards to be single sleeved or unsleeved, it will hold even more. The boxes are good for storing decks as well, as they are stackable with other PX4 XLs, but also with the original Prime X4 card case.
