Veiled Sentry
Enchantment (CMC:1)
When one of your opponents successfully casts a spell, if Veiled Sentry is an enchantment, Veiled Sentry becomes a creature with power and toughness each equal to the total casting cost of that spell and that counts as an Illusion.

10/4/2004 If the spell is no longer on the stack when the triggered ability resolves, the converted mana cost of the spell is still remembered. 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.
