502.7 - Protection

502.7a - Protection is a static ability, written "Protection from [quality]." This quality is usually a color (as in "protection from black") but can be any characteristic value. If the quality is a type, subtype, or supertype, the protection applies to sources that are permanents with that type, subtype, or supertype and to any sources not in play that are of that type, subtype, or supertype.

502.7b - A permanent with protection can't be targeted by spells with the stated quality and can't be targeted by abilities from a source with the stated quality.

502.7c - A permanent with protection can't be enchanted by Auras that have the stated quality. Such Auras attached to the permanent with protection will be put into their owners' graveyards as a state-based effect. (See rule 420, "State-Based Effects.")

502.7d - A permanent with protection can't be equipped by Equipment that have the stated quality. Such Equipment become unattached from that permanent, but remain in play. (See rule 420, "State-Based Effects.")

502.7e - Any damage that would be dealt by sources that have the stated quality to a permanent that has protection is prevented.

502.7f - If a creature with protection attacks, it can't be blocked by creatures that have the stated quality.

502.7g - Multiple instances of protection from the same quality on the same permanent are redundant.
