I will try to writte the best possible, my english is pretty bad but i will try my best, ty for the comprehension.
Well nazeebo can carry games like a crazy pusher and as a heavy dmg dealer too, all we need is a stronk early game, if is possible a solo lane where you take solo exp and you can farm your death ritual.
In firsts levels you must try to do dmg to all minions and play a safe lane, with oponnents like zagara is better play safe and a use your "q" for poke and your "e" for push.
In late game nazeebo is very squishy, he can carry a team fight pretty good with his "w", and the dmg what he can make is amazing, the spiders of his "q" do a lot of dmg and if you can use your "e" good more periodical dmg comes really good, you will cary the tf that's for sure.
Nazeebo's hero ability is awesome, you can take camps solo with your zombie, and if you throw to an enemy it makes a lot of dmg, and zombie's ability is fine too make dmg and slow heroes.
And for conclude, if you want to win, you must play nazeebo ^^

The same than the first chapter, but in team fights you must posisionate with a good distance and throw your hero ability, it makes a lot of dmg, an can kill assassins very easy
This build is more oriented for a heavy dmg
