Saw something on Reddit about how Xerath Soraka is insane on bot lane, due to Xerath's passive/W and infinite mana from Soraka. Are there any other comps that you can think of that absolutely wreck on bot lane even though you don't see them very often?
Riven Akali works well, as well as Riven Xin. Volibear Akali is actually pretty nuts too.
