Maleficent Dragon is a Premium Box Tsum. On the Japanese version, she is regularly available from Premium Boxes. On the International version, she is a Limited Time Event Tsum and is not obtainable through purchasing Premium Boxes outside of the event. She was introduced to the International version in tandem with the Villains Event in November 2016.
Maleficent Dragon is similar to Maleficent, clearing Tsum Tsums surrounding the chain which is connected by the player. Her skill also clears surrounding bubbles as well. Her base time is 4 seconds and the base number required is 22. Higher skill levels will reduce the number required to fill in the skill meter and increases the time limit.
Try to connect as many chains as possible within the time limit given by the skill, whether it's short or long, and if there are big/large tsum tsums, try to clear them by connecting them or connecting chains close to them. Connecting more tsum tsums gives you more points, so you need to be efficient when activating her skill.
