Moskov

In teamfights, use Moskov's Ultimate to slow a target, then activate it again to blink behind them and use his 2nd Skill to knock them into a stun before finishing them off with Basic Attacks.

In the laning phase, use Moskov's 1st Skill to blink to a position to stun the target with his 2nd Skill, then get in as many Basic Attacks as possible to reduce the cooldown of his skills.
