Rule 702.16i
Official source text from the 10 August 2018 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.
