Rule 702.14i
Official source text from the 1 October 2010 Rules release
"Protection from everything" is a variant of the protection ability. A permanent with protection from everything has protection from each object regardless of that object's characteristic values. Such a permanent can't be targeted by spells or abilities, enchanted by Auras, equipped by Equipment, fortified by Fortifications, or blocked by creatures, and all damage that would be dealt to it is prevented.
