Enchantment
When an opponent casts a creature spell, if this permanent is an enchantment, this enchantment becomes a 3/4 Gargoyle creature with flying and protection from red.
It was a moment in time, cast in stone—a moment whose time had come again.

Rulings

A noncreature permanent that turns into a creature can attack, and its 
abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of their most recent turn. It doesn't matter how long the permanent has been a creature.

A face-down creature spell will cause Opal Guardian's ability to trigger (if it's an enchantment).
