Goroth, Emerald Alpha

When Goroth enters the battlefield, create a
tapped colorless artifact token named Mox
Emerald with "{t}: Add {g}."
Permanents you control named Mox Emerald
have "{t}: If target creature you control doesn't
have trample, put a trample counter on it. Otherwise, if it doesn't have vigilance, put a
vigilance counter on it. Otherwise, if it doesn't
have hexproof, put a hexproof counter on it."
