The effect that turns it face-up is a replacement effect. It doesn't use the stack and can't be responded to.

You may not turn a face-down spell face up. You may not turn a face-down permanent face up unless it would have morph while face up or an effect specifically allows you to turn it face up. Illusionary Mask's ability has you turn a face-down creature face up if it would assign damage, deal damage, be dealt damage, or become tapped, but not for any other reason. For example, if you use Illusionary Mask's ability to cast a black creature face down, you can't turn it face up just because it's being targeted by Terror.

Both the amount and types of mana you spend on {X} are taken into account while you're choosing a creature card from your hand. For example, if you spent {U}{U} on {X}, you can choose a creature card with mana cost {U}{U}, {1}{U}, {2}, or {W/U}{W/U}, among other possibilities, but not one that costs {2}{U} or one that costs {G}.

The creature's "enters" abilities (and any other abilities relating to the creature entering) do not trigger when it turns face up.

Only the controller of the face down creature can look at it.

The creature enters face down, so none of its "enters" abilities will trigger or have any effect. Also none of its "As this enters" abilities apply.
