Murky vs Thrall
Thrall can do a lot of damage to Murky. But Thrall has to catch Murky first so it is safe to lane against him. Murky should reserve his bubble in case he is hit with Thralls root. Murky should also back off when Thrall winds up for his wind fury attacks. Trying to stack slimes on Thrall is not recomended.
Once you Murky gets Fish Tank he can go toe to toe with Thrall and win.
