Text:

When an opponent casts a creature spell, if Opal Titan is an enchantment, Opal Titan becomes a 4/4 Giant creature with protection from each of that spell's colors.

Rulings:

10/4/2004 If the spell was colorless (an artifact), this card does not get any form of Protection.
10/4/2004 When it turns into a creature, it is no longer an enchantment.
10/4/2004 It changes into a creature even if the spell is countered.
10/4/2004 It triggers when the spell is cast, which means it becomes a creature before that spell resolves.
4/1/2008 A “creature spell” is any spell with the type Creature, even if it has other types such as Artifact or Enchantment. Older cards of type Summon are also Creature spells.
8/1/2008 A noncreature permanent that turns into a creature can attack, and its <img src="/Handlers/Image.ashx?size=small&name=tap&type=symbol" alt="Tap" align="absbottom" /> 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.
