What role do you like to play? Because that can help narrowing the champions down to find one right for you
I'm probably going to get a lot of Mobafire-Hate Downvotes, but Infectious Lepar has put together an excellent guide to finding champions that work well for you.
That said, Snorlax with a Chesto Berry is the definition of Sleeper OP. 
+ Ahri "E" is pretty darn close. Just the issue of having an Ahri on the other team...

im a bit slow on my play and have a hard time keeping up with the faster champs and all the combos lol so the less i have to do the better and i dont do support
