Hierarchy

Hierarchy is a term used to describe the rank of a Egyptian God Card. "Slifer the Sky Dragon" and "Obelisk the Tormentor" have a hierarchy of 1, while "The Winged Dragon of Ra" has a hierarchy of 2. God Cards are not affected by the effects of God Cards with a lower hierarchy, nor are they destroyed in battle by them either (excluding the rare circumstance that 2 or more God Cards with a lower hierarchy attack a God Card of a higher Hierarchy at the same time). God Cards of the same Hierarchy are vulnerable to each other's effects.
