Murky vs Johanna

Johanna is very easy to lane against. The main thing is to avoid her stuns. You won't be able to kill Johanna as she has plenty of time to escape and can neagate your slows with her shields. But you can force her to retreat if you time your slimes well and avoid her stuns.

After you get Fish Tank you will be able to go toe to Johanan. However Fish Tank stops working when you are blinded. So bubble up when blind hits you and you can easily win. Of cource Johanna can just run away whenever she feels like it which is frustating.
