I'm going to say the basic to think up. You can use the passive to survive. If they are runing alone behind you, you stop in a jungle zona and wait they leave. you can do a good attack if you wait in one street and with your team you can gank. The first attack is good to help and survive, on the combat is important use it when the enemies attack you. It isn't necessary put a lot of mushrooms in a littel space this only prodice 1 effect. If you want to push confidently you will need put 1 mushroom on the street just back you. You need be care with the stoons and strong champions. I use this build sometime and is good to combat and put strong mushrooms. My record is 31/11/17. This build is better than ad because this use all the skills and have a got respectable damage/second which is 151 plus the toxic shot. if you use this build you will shoot 2.500 attacs/second.
