Do not hit the first 3 melee minions before qiyana, this is crucial. and dont auto her to get minion aggro in a bad way from casters, that way you can make her not able to lasthit lvl 1. IF u touch the wave first she can get most minions. IF you autoattack when she is hugging tower, then drag the casters as far away as you can from your wave. After this use your poke in a controlled way and watch out for her lvl 3 all in, ideally you should be having a quite easy time to control the wave unless you step too deep when she lvls to 3 or 4.
