Eye
Eye is a seldom used black creature subtype used for cards that depict magical sentient beings that appear as large, floating, single eyes.
Evil Eye of Orms-by-Gore from Legends used to be subtype Evil-Eye until it became became a Horror in Sixth Edition. When Evil Eye of Urborg was printed in Time Spiral, Evil Eye of Orms-by-Gore got a tweak to interact with it. They both get the new Eye type and could therefore attack together.
Other creatures which conceivibly could have been Eyes are Unblinking Bleb and Wandering Eye. They are Illusions instead.
