# Prison Barricade Prison Barricade is a modest common from Invasion that appeals primarily to limited players and casual builders rather than serious collectors. The card's straightforward defensive ability—a small creature that blocks effectively—made it serviceable in draft but unremarkable in constructed formats. Collectors typically view it as a bulk common with minimal monetary value, though it remains accessible for anyone completing Invasion sets. The foil variant exists but commands little premium over nonfoil copies due to the card's limited demand. For most collectors, Prison Barricade represents the kind of forgotten common that fills out set collections without drawing particular attention or investment interest.
