Murky vs Lunara
Murky can definitely lane against Lunara. However he will not be able to touch Lunara. Just focus on the minion waves. Murky's bubble will clear poison stacks so make sure you use that to good affect.
Although Lunara main damage comes from poison she also does physical damage with her auto attacks. Fish Tank will help with that. Once Lunara is slowed she is in for a bad day. Too help run her down Slippery When Wet is highly recomended.
