Sealed

"Sealed" is a term that refers to a Skill being neither negated nor removed, but simply has filled the condition for it to be used for a single turn. Although, it does not say as such, Character Card Skills are always Sealed Skills that cannot be negated or removed, and can only be used once per turn. Keep in mind that if you use the effect of a card that then becomes Sealed afterwards, that ALL copies of that card are Sealed. Keep this in mind, as some cards like "Child Clarice" cannot activate their effects more than once per turn.
