Cho' solo? you better pray because you'll die! Cho' top can easily solo and with his E, he has good poke and can farm pretty easy. why wouldn't you solo top cho? This is my first build too so not a lot will be added.

Pros

tanky
Good CC
easy to farm
with ult, can easily destroy top

Cons

a little mana hungry
will spend most of the time around turret the beginning game

If you just use your Q followed by your passive E, you should take any champ to pretty low health or at least backing away. Once his low health, Just nomnomnom his face with your ult
