is a decent start.
Some good top lane picks right now are Jax, Renekton, Wukong, Rengar, and I think Warwick is really strong top lane as well. Try those out. Warwick, Rengar, and Renekton have great sustain and typically aren't banned often. Jax is very strong, but is banned quite often.
has always been a strong top laner. He's easily countered by Garen and Darius, but if you can make it to late game, you'll be able to fight nearly anyone.
is 'the' top laner. A heavy AD Bruiser, with great damage, CC, tankiness, and sustain. All around a good pick.
doesn't have sustain until you build it, but around LVL 6, you can fight anyone with a well played E->Q->R combo.
is a great champion for sustaining in lane. He is tanky, has great sustain and damage throughout the game. Lane bully into a tanky assassin/fighter late game. Did you see him in the cinematic?! What a badass.
is especially interesting. People underestimate what he can do. His passive along with a Doran Shield/Blade will give crazy amount of sustain in lane. You won't be able to push or harass very well, but Warwick can 1v1 like a god. His Blood Scent gives him Baron Control and a way to quickly escape from a gank.
Anyway, that's just some of my top lane picks. Good luck out there!
