Nocturne Top
Why dont people play this? His only counter matchups are Renekton and Tryndamere.
He has unlimited sustain, that no top laner can effectively poke through. (Umbrablades, Corruption Potion, Biscuits+Timewarp tonic, overheal, Bloodline) His kit inevitably keeps the lane hard shoved onto the enemies tower, allowing much freedom to ward, assist your jungler, collapse on mid, recall+Ult bot lane/TP ult bot lane, use R to protect your jungler, and lose little to no CS in doing so. Possibly the best tower smasher in the game due to all the steroids built into his kit(So youre gonna get tower plates, and likely tower firstblood). He has reasonable, not great gank escape(Fear one+follow your Q trail away). But he doesnt really need excellent gank escape, since he's constantly free to be aware of the entire top side of the map..
cons- Cant properly freeze.
His level 6>recall+buy Serrated Dirk>Walk bot>Ult bot lane while they are lvl 4>TP back to top. Is so effective.
