# Circle of Protection: Green Circle of Protection: Green is a common from Classic Sixth Edition that represents a straightforward defensive tool from Magic's early design philosophy. Collectors recognize it as part of the broader Circle of Protection cycle, which appeared across multiple sets with different color restrictions. The card's appeal lies primarily in its historical significance rather than power level—it exemplifies how older sets approached color-hosing effects through simple, elegant mechanics. For set collectors, this common fills a necessary slot in completing Sixth Edition. The nonfoil version remains readily available and affordable, making it accessible to players building comprehensive collections. Its modest utility and common status mean it rarely commands collector attention beyond completionists, though it serves as a useful reference point for understanding Magic's design evolution.
