Tips to maximize your impact

Mark, then two dashes
Hit with Crescent Strike (Q) before Lunar Rush (E): on a target marked with Moonlight, the dash has no cooldown and you can recast it right away.
Weave autos between your spells
Weave autos between your spells: after each ability, Moonsilver Blade (passive) boosts your attack speed for 5 seconds, and your third hit cleaves nearby enemies.
Shield before you engage
Cast Pale Cascade (W) before you engage: you gain a shield, then a second one when the last sphere explodes.
Pull their whole team in
Cast Moonfall (R) in the middle of their team: it pulls in and slows nearby enemies, and hits harder for each champion pulled after the first.

How to counter and exploit weaknesses

Stay behind your minions
Keep minions between you and her: Charm (E) stops on the first enemy hit, and without it her burst lands far less often.
Dodge the return of her orb
If you can only dodge one pass of Orb of Deception (Q), dodge the return: it deals true damage, which your resistances don't reduce.
Play hard when her R is down
Play hard once she has used the dashes of Spirit Rush (R): she has nothing left to escape with, and its cooldown is 140 to 100 seconds.
Group up when she roams
When she roams, avoid walking through the jungle alone: Charm (E) then Spirit Rush (R) let her catch an isolated target by surprise.
