It's ranged vs melee so auto attack as much as you can and answer her Q with auto attacks and Q her when she tries to last hit. Level 2 and 3 you should be VERY careful because she can 100-0 you. The proper way to do it is in front of you into and . You should then before the dagger drops on her but it might be hard to land it because of the movement speed she gets from . Either you land or miss it, then move right or left and NOT behind. If you get hit by both daggers, you will die. After 6, keep for her ult. If she and you have no or there are creeps between you two, just out of her ult and dash in again if you have enough damage to kill her. Ward the sides, ping when she roams and follow her.
Overall, a matchup that favors but can definitely turn pretty ugly if your opponent is a god or you play it badly.
