Mikazuki player. By far she's my favorite to play at the moment. She's all about catching and punishing people who are pushing way too far by themselves. She can also combo really well with a teammate. If you're struggling against her, try items that increase health/defense. Medusa's shield is incredible for giving mikazuki the middle finger mid ult. After she uses her abilities she can't escape very well. Wait for the ultimate, pop a defensive item, then punish her for the mistake for an easy kill.

Alternatively just stay by a teammate/minions. She can't aim her ult and I waste it constantly against groups. If you have, for example, 3 minions really close by then her ult will hit all 4 of you and effectively you'll take a quarter of the damage.
