Chang'e

In teamfights, get the shield from Chang'e's 2nd Skill, then use her 1st Skill to poke enemies, and follow up with her Ultimate if the 1st Skill was on target. Chang'e needs to move around during her Ultimate to keep herself safe and make sure the meteors can hit the target.

In the laning phase, get the buff from Chang'e's 2nd Skill first, then mark the enemy with her Basic Attacks. Cast her 1st Skill to slow down low HP enemy, and finish them off with her Ultimate.
