Hello, I am interested in buying a 4800 champion. I was thinking about Fiora or Vayne. I already have Riven,Rumble,Fizz and a few more 4800. Im really just looking for a good champion to carry me out of this silver hell. Thanks again :) 
Fiora is pretty much instabaned in all my games (i'm silver too), vayne is baned a lot too, so both aren't really good choices, since you won't have oportunity to use them XD. Volibear is good to carry low elo, since people don't know how to counter him, and he's full tank while dealing decent damage.
