Break Open (ONS-190) is a common red Instant. It turns target face-down creature an opponent controls face up, allowing you to reveal and disrupt morph plays without paying the creature's morph cost. It is primarily used as inexpensive morph hate and a tempo interaction in decks that expect face-down creatures.
