Esmeralda

In teamfights, enter the fight using Esmeralda's Ultimate, then use her 1st Skill to gain Movement Speed and steal the shields of nearby enemies, before finishing them off with her 2nd Skill and Basic Attacks.

In the laning phase, use Esmeralda's 1st Skill to approach the enemy and hit them with her 2nd Skill followed by Basic Attacks. Her 1st Skill should be up again soon thanks to the CD reduction from her 2nd Skill, so use her 1st Skill again for Movement Speed and shields, and continue using her 2nd Skill and Basic Attacks.
