Maleficent

Maleficent is a Premium Box Tsum.

Information
Maleficent Tsum is a Chain Burst Skill Tsum. While her skill is active, she will clear surrounding Tsums of any chain you clear. Her base time is 3.3 seconds.

Maleficent is a Villain Tsum, due to the fact that she is a villain to Princess Aurora. However, she doesn't belong to the Sleeping Beauty series because her Tsum is based on the live-action movie titled Maleficent.

Strategy
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.
